Note: This computer is W7 but I have another here with me that is
dual-boot W7/Ubuntu 18. The new scanner could be used with either, I'm
not fussed, just as long as it works!

Just replacing the rubber drive belt, is an example.
Mine has to come apart, so you can change the CCFL tube.
Mine has two tubes, and a spare CCFL came in the box with it!
What were they thinking ? That the scanner would last

Sometimes a scanner needs to come apart, because the
transport screw is not engaging properly.
And cleaning is necessary, in dirty environments.

A right to repair doesn't exist for such devices
and even for those for
which it does, it only applies to professional repairs. It also seems
to be EU derived legislation, so may well be slated for repeal.
See <https://researchbriefings.files.parliament.uk/documents/CBP-9302/CBP-9302.pdf>
As such I wouldn't expect repairability to be a consideration for
consumer grade scanners.
I think there may have been legislation about ease of disassembly, but
only as a prelude to recycling, not repair.

I have an Epson GT-2000 scanner, but for the bulk copying of archive material I use a camera. Brief notes on this:Set to a fixed ASA; 100ASA is OK. Consider using RAW file type. If auto focus works OK use it, because the distance can vary with a thick book. Don't fill the frame, allow a margin, because focus can be slightly out and there can be chromatic aberration
Find the zoom position that gives minimum pin cushion (etc) distortion. This is likely to be near the mid-point. Use a tripod with the camera looking perfectly straight down to avoid geometric distortion. Set the camera to max resolution and quality.

Mine has maybe 15 years. Epson Perfection 1650. I don't see a date in

bought in a physical shop).
I know I wondered if mine was using USB1, because it is slow

Yes, they can last quite a while. My Epson Perfection V60 is 13 years
old and has been working on Vista, 8.1 and now 11, all with the exact
same software (from the original CD).

Don't know about yours, but if indeed 15 years, then it's probably
USB2. If it's much older, it could indeed be USB1.

An LIDE 60 with a new belt, would be an LIDE 300 :-)
Maybe buying the belt would be cheaper ? With spare
parts, that is not necessarily the case. Sometimes
(unfortunately for the landfill), the new gadget is
just too cheap to ignore.
Firing up the olde Google, you can find repair procedures
for scanners. Scanners may use plastic gears and rubber belts for
the transport. The stepper motor itself should be reasonably
reliable. The transistors that drive the stepper motor,
maybe a bit less so.
https://www.ifixit.com/Guide/Canon+ImageCLASS+MF4350d+Scanner+Belt+Replacement/18773
If you keep the scanner in a high ozone environment, even with
a synthetic rubber belt it might someday fail to function
correctly. I think regular latex rubber, is the most susceptible
to ozone attack.
The belt moves the sled along. If there was a bit of gear
slap, it's the fact that the belt pulls the sled in the
one direction during the scan, that helps press the gear tooth
to the toothed belt.
If the belt tension is wrong, you may notice a line of pixels is
repeated, or it "looks like the paper moved part way through the scan".
If the belt is marginal, a user may spot a blemish in the scanned
result. Maybe a belt tooth is damaged for some reason, and every
time the belt hits that "bad spot", a slight jump occurs.
The step size of the motor, defines the resolution. If it's 4800 DPI,
the head moves slowly, and in single steps. If it is scanning at
300 DPI, maybe it takes 16 quick steps, stops on a dime, and captures
a row of pixels, then galomps another 16 quick steps, stops and
does another row. It's the stepper motor that defines integer ratios
of resolution in one of the scanner directions of a flatbed scanner.
The fixed array of pixels in the other direction, defines the
maximum resolution in that direction.
Sampling at high DPI, is typically unnecessary. Only photographic
sources have "grain size" that makes extraction of high DPI info
useful. On print media using halftones, the Nyquist criteria applies.
Like a newspaper is particularly low res, and you can take a
magnifying glass and count the dots per inch. Scanning a piece of
newsprint at 4800 DPI, is a waste of electrons :-) Count the pixels
and scan at 2X the resolution, so the file size will be reasonable and
the scan will finish quickly. While scanning at resolutions
higher than Nyquist predicted adds some small improvement to
the content, it's at the cost of extra storage space. And it's
not likely worth it.
OCR programs, you'd be surprised that some of them at least, do not
like high resolution scanning. Maybe 200 DPI is their target. The need
to follow the edge of letters versus scanning at high resolution, leaves gaps.
If you want to scan a photograph, that's when the 4800 DPI might pay off. >Because there's no print halftone, and it's the grain size of the
media that partially determines how much you can zoom in.
The job of the transport, the gears and belt, is to move the head
accurately in one direction, without too much gear slap throwing
off the true position.
Scanners other than flatbed type, have different criterion. It
may even be possible for a scanner to use a 2D array and some
DSP processing to simulate "start/stop" scanning, while the
actual transport just whisks the paper along. That's the V
shaped paper path ones.
The ultimate scanners are just "cameras" with correction
for optical effects. That's a very large 2D array, that captures
the sheet in one photo. You can't do that with an ordinary
camera on an arm, because of the optical distortion in the
field of view.
There are drum scanners, if you want an outstanding scan. Your
material must be wrapped around the drum, and the drum spins
at a decent speed while a laser scans it. Typically you go to a
print shop and rent the scanner to do those scans. The machines
are not priced for home ownership.

Not exactly an answer, but have you considered just getting
a cheap printer duo? I haven't bought a dedicated scanner
for many years. My curent printer is an HP envy. I think it
was about $100. It comes with a scanner that does up to
600 dpi. Works fine for what I need. It's hard to imagine
needing greater quality. When it dies I'll buy another. It's
like computers. Unless you're doing very specialized work,
the cheap one is more than powerful enough.

I find the worst that you mention is lighting - relying on the ring
flash tends to light the centre of the page but there is a noticeable
and distracting drop off towards the corners, while using natural light
from a window gives a drop-off across the page.
Again as you have mentioned, as you go through a book, the distanceGenerally a long focal length can minimise pin cushion. But photoshop fixes it easily anyway.
between the lens and the page varies, and opposite pages might be at different distances, so you have to keep an eye on the focus.
I once tried the above method to digitise an old map, but couldn't find
a combination of camera height and zoom that wouldn't give unacceptable pin-cushion distortion, and eventually resorted to scanning it in
sections, stitching these together to make the final image.
Hence this is not my preferred method of digitisation, as I thinkWell yes, you can't beat a good quality scanner. But I was talking about bulk scanning, where the job just wouldn't get done if each shot meant putting a page in a scanner. The most extreme example I've had was scanning a book of text for OCR. The OCR
scanning tends to give better results. However, thanks for the advice,
which may benefit others.

One thing to be aware of, is at least one model will
not allow scanning, unless there are working inkjet carts
in the machine.
You have to do extra research, by reading customer reviews, to see
where they are hiding the handcuffs this time.
If I was the scanner designer in your machine, I would make
sure the cartridges went through a cleaning cycle, for each
sheet you scanned :-) Do you see the opportunities in
a business like this ? Imagine the amount of cussing and
swearing your customers will be doing, any time your

You'll need a spudger.
And we get a view of the PCB there too.
It's possible that scanner is bus powered, and that's
why there is no power supply board in there.

Mine has maybe 15 years. Epson Perfection 1650. I don't see a date

Well, that's not a problem for me: I use Linux :-D
Funny thing is that I have been using the epson2 driver for many
years, but this last year that driver failed, while the epson1 works.
Go figure. I have not given thought to it.
If your old scanner was expensive, or carries out
a function your newer scanner doesn't have (dust and scratches),
it might be worth using Vuescan.

Yes, NLS website has also made many such old maps available online in
the same manner as Google Maps or Bing Maps, and their site has the
ability to fade between two maps of the same area using the control on
the left. This has been extraordinarily useful in locating where, and sometimes even why, many of our old family photos have been taken. For example, this ...
https://maps.nls.uk/geo/explore/#zoom=12.5&lat=57.27802&lon=-5.54239&layers=11&b=9
... shows that the A87 into Kyle Of Lochalsh has been radically rerouted since our photo was taken, and why our pictures of Eilan Donan and Loch
Alsh were taken from what is now a by-road above the castle not from the shore where the current main road is. That old by-road was then the
main road. Here's the Loch Alsh photo ...

In this way I've been able to locate and name all but three of the
landscapes we have, despite the fact that mostly Ma never wrote anything
down about them.
Apologies for the cross post, but this is a hardware not an OS or software question.
I'm at relatives hoping to scan their stuff for the family archive, only
to find that I forgot to lock the transport mechanism of my scanner - a CanoScan LiDE 300 - before packing it for the journey, and further it
seems to have been upside down in the car. Not only was the underside of
the glass covered in dust from the ancient documents I've scanned in the past, but it seems so is the scanner head, because I'm getting lines, not just specks, across all the scans. I tried dismantling and cleaning it, which has got rid of the specs, but not the lines, and as a result some of the plastic surround no longer locks properly back into place, though I
don't think I broke any catches, certainly I tried to be careful not to do so, and further each scan now pauses one or two times and then restarts,
thus tripling the time taken for each scan.
Can anyone suggest a reliable basic model of scanner which allows one *EASILY* to clean the inside of the glass and the mechanism?
Note: This computer is W7 but I have another here with me that is
dual-boot W7/Ubuntu 18. The new scanner could be used with either, I'm
not fussed, just as long as it works!

That's something I've never noticed. I don't do much
printing, and scanning is occasional, typically to scan in
family photos and such. There have been times that I've
wanted to digitize text, but any old scanner, with an old
version of Textbridge I once got free with a printer, handles
that job well enough. So I just go for the cheapest duo.
Anyone who wants something like good photo printing will
have to look at a much better class of printer, but for my
needs, the base HP is excellent.
I did find that Epson printers were sleazy. They just decide,
out of the blue, that I have no more ink and must buy some.

of water for 5 minutes, dab it on a paper towel, and it's

I think that part of the reason I don't print is that the technology
is just not very good. Ink runs if it gets wet. Photos don't
print any better than they did 25 years ago, unless you get
a very expensive printer. Things break without getting a lot
of use out of them. The price of ink is ridiculous. It's almost
economical to just buy a new printer whenever the cartridges
run out.
I suppose that I've also got used to digital. There was a time
when I carefully maintained "real" copies of mailing lists,
programming code, etc. Gradually I got comfortable with disk
backup and couldn't justify wasting all that paper. So now I
mostly just print out business receipts and tax forms.

Not exactly an answer, but have you considered just getting
a cheap printer duo?
I haven't bought a dedicated scanner
for many years. My curent printer is an HP envy. I think it
was about $100. It comes with a scanner that does up to
600 dpi. Works fine for what I need. It's hard to imagine
needing greater quality. When it dies I'll buy another. It's
like computers. Unless you're doing very specialized work,
the cheap one is more than powerful enough.

"With Scannable, you simply position your document so it fits within the viewfinder
(your iPhone's screen). The app will quickly automatically capture it, then straighten,
sharpen and otherwise improve the quality of the image.
With a creased receipt, for example, it virtually eliminated the fold marks from the
scan and evened out areas of different contrast. And with those extra-long receipts,
I didn't have to capture them in sections -- the app did fine when I pulled back to
snap the entire thing at once."
Normally, I would be concerned about the poor lighting when you
shoot pictures with digital cameras in ordinary room light. Like
I'm all the time throwing shadows onto the things I'm trying
to shoot. A flatbed scanner does a relatively good job on lighting.
To use your smart phone idea, you need to shoot a picture of
a precision grid, and verify the distortions in the optics
are being corrected by your App.

Virtually all of the schools I used, have been bulldozed.
When I did an electrical and electronic engineering degree in 1981, one
of the students asked the lecturer in charge of the laboratory work
whether he'd organise a demonstration and practice session in soldering
for us, for the times when we needed to solder leads to connectors or variable resistors (eg volume controls). The lecturer really shot that
idea down in flames. "Engineers don't do soldering. They have
<disdainful contempt> technicians </disdainful contempt> to do that sort

I gather the attitude was similar in mechanical engineering, where
knowledge of how to machine parts on a lathe was looked down on as technicians' or labourers' work.
There are some skills which are standard life skills. Wiring a mains
plug, being able to change a car wheel, how to check the oil level in
the engine and to fill it up if necessary, checking the voltage of
battery and the resistance of a fuse (to tell whether it is blown).
And those skills should be taught equally to men and women, just as
basic cookery, how to use an iron and an automatic washing machine, how
to sew a button on a shirt or darn a hole in a sock should be taught to
men as well as women.
Incidentally, thinking of things which are traditionally "men subjects"
or "women subjects", on my university course of about 40 students, there
were *two* women - and one of those changed to do law after the first
year. And that year was not exceptional: engineering, and elec eng in particular, never attracted many women applicants. Even heavy
engineering, such as mechanical and civil engineering, attracted more

thought that she was very odd for wanting to study a technical subject
at university. That's the 1980s we're talking about, not 50 or 100 years earlier: I'd expect schools to be more enlightened than that.

So the South American guy comes into the lab, and walks over to the
bench he's been assigned. The soldering iron had already been switched
on. I can't remember the context (what he was working on), but I look
across the lab and to my horror, he's reaching for the wrong end of the soldering iron. And before I can yell a warning, he has the thing in hand! And the next thing I'm thinking is "God damn it, there's no burn cream
in our medical kit". Because of course, who would ever burn themselves
in our lab. The med kit had gauze, tape, and a bottle of Aspirin.
That's an indication that perhaps someone has not soldered before.
Incidentally, thinking of things which are traditionally "men subjects"
or "women subjects", on my university course of about 40 students, there
were *two* women - and one of those changed to do law after the first
year. And that year was not exceptional: engineering, and elec eng in
particular, never attracted many women applicants. Even heavy
engineering, such as mechanical and civil engineering, attracted more
women. The one woman who remained on my course said that her school
thought that she was very odd for wanting to study a technical subject
at university. That's the 1980s we're talking about, not 50 or 100 years
earlier: I'd expect schools to be more enlightened than that.
Not sure about engineering, but a physics undergrad course I’m familiar with now has slightly more females than males. There are now roughly equal numbers going on to PhD study. Postdoctoral researchers are now
represented
by more females than males.

Few of my friends, neighbors, and co-workers would know what a screw
driver is, and those few would be incapable of using one if they had
one. They hire others to do that.
This is probably why our school system back home, had Shop Class. And
not Shop Class As A Trade. Just basic familiarity with tools. Even a
STEM student, learns how to use a screwdriver there. And how to use a
two horsepower surface planer. Or bend steel on bench presses and weld
it. Or wire an electrical cord.
Of course, it's unlikely to be like that today. Made too much sense. Virtually all of the schools I used, have been bulldozed.
When I did an electrical and electronic engineering degree in 1981, one
of the students asked the lecturer in charge of the laboratory work
whether he'd organise a demonstration and practice session in soldering
for us, for the times when we needed to solder leads to connectors or variable resistors (eg volume controls). The lecturer really shot that
idea down in flames. "Engineers don't do soldering. They have
<disdainful contempt> technicians </disdainful contempt> to do that sort
of work for them.
We were not impressed with that answer. Everyone who is going to work
with electronic components needs to be able to do the basic tasks. Maybe there would be times when it would be left to other people, but you
still need to be able to do it yourself for times when there isn't a technician around.
I gather the attitude was similar in mechanical engineering, where
knowledge of how to machine parts on a lathe was looked down on as technicians' or labourers' work.
There are some skills which are standard life skills. Wiring a mains
plug, being able to change a car wheel, how to check the oil level in
the engine and to fill it up if necessary, checking the voltage of
battery and the resistance of a fuse (to tell whether it is blown).
And those skills should be taught equally to men and women, just as
basic cookery, how to use an iron and an automatic washing machine, how
to sew a button on a shirt or darn a hole in a sock should be taught to
men as well as women.
Incidentally, thinking of things which are traditionally "men subjects"

A possibility that nobody ever seems to consider (or maybe they're apprehensive about suggesting it) is that maybe men and women have
different interests and thus there's no need to look for any external selection process because people are effectively selecting themselves.
I've been involved in recruiting trainee television engineers and
discovered that hardly any women applied, maybe around ten percent of
the total, and this became reflected in the resultant numbers of
recruits. You can't appoint people who don't apply for things.

p.s. for a cheap scanner look for one of the Medion badged Aldi ones
used. I prefer the one on my Brother all-in-one as it has a sheet
feeder. It does only scan one side, but my OCR software can cope with
odd and even pages.
if
there are too few applicants, the limit is to accept every single one of them, but even that may not be enough - you can't manufacture applicants.

I quite agree. Certainly unethical and likely to lead to resentment from people who have had to meet higher entry criteria. And probably illegal, though I don't know enough about employment law to be certain.
The point I was making was that even if you are prepared to break ethics
and the law, you may *still* find there are insufficient people of one
racial or gender category.
I suppose you can still favour one race/gender as long as the candidates
meet the stated entry criteria and have been whittled down to interview stage, where the choice is then fairly subjective, based on "could I
work with this person?" and "do they have the personal skills (in
addition to the technical skills on their CV) to do the job?".
From the limited amount of job interviewing I've done (interviewing
students who had applied in writing for a gap-year job) things are very subjective:
- some CVs and letters were very badly presented/organised/printed, and
there was a tendency to over-compensate and say "that *shouldn't* matter
so maybe I need to give them a chance to present themselves at interview"
- one candidate was a bit too perfect: his CV was immaculate and he had
prior experience in a gap year between A levels and university of
running a small business; he was able to talk fluently about it so I
don;t *think* he was bullshitting. And yet (there's always an "an yet"!) something didn't seem right

Not exactly an answer, but have you considered just getting
a cheap printer duo?
Each to his own, of course, but my vote is against such devices. I
don't like the idea of combo hardware. If one component fails, you
need to buy another combo unit.
Moreover with a combo unit, you may get a good printer, but a poor
scanner (or vice-versa). With individual units, you can choose the
best of each type or the one of each type that best fits your needs.
And that second point applies equally to software suites. Similarly, I
am against the idea of software suites. As an example of what I mean,
I prefer Corel WordPerfect to Microsoft Word, but Microsoft Excel to
Corel Quattro Pro.
One other point regarding printer/scanner combos: the printer in most
such units (especially the cheaper ones) are inkjets. In my opinion, a
laser printer is almost always a much better choice than an inkjet.
The rest of my Officejet went belly-up about two years ago, so I wentI haven't bought a dedicated scanner
for many years. My curent printer is an HP envy. I think it
was about $100. It comes with a scanner that does up to
600 dpi. Works fine for what I need. It's hard to imagine
needing greater quality. When it dies I'll buy another. It's
like computers. Unless you're doing very specialized work,
the cheap one is more than powerful enough.

Twenty years ago I would have agreed. But I think I paid $80 for
my current duo, with 600dpi scanning and very good printing. At
least it's very good for business docs, tax forms, and such. I gave
up on printing photos. The woman I live with has a printer for that.
It was something like $2,500 + 9 ink cartridges. I don't need such
a thing.
I haven't even seen a stand-alone scanner recently. Looking
at Amazon I see they're available, and 2400 dpi is not unusual.
But I rarely use more than 300dpi. Data just doesn't come that
small, even in a photo, that I need 2400dpi. And what would I do
with it? A 3x5 photo becomes many times the size of my monitor
and close to 300 MB.
If/when my current duo fails, I'll probably buy the cheapest
replacement. The current version of my HP Envy is about $100.
But of course it depends on your needs. If I print 30 receipts,
5 contracts and 20 tax forms in a year, my main problem is
not quality. Rather it's how to avoid buying 2 cartridges of
ink every year to only use a small fraction of the content before
it's dried out.
People say I should get a laser printer, but they seem to start
around $250 for B/W printing. Fine for a small law office, but silly
for my need.

Twenty years ago I would have agreed. But I think I paid $80 for
my current duo, with 600dpi scanning and very good printing. At
least it's very good for business docs, tax forms, and such. I gave
up on printing photos. The woman I live with has a printer for that.
It was something like $2,500 + 9 ink cartridges. I don't need such
a thing.
I haven't even seen a stand-alone scanner recently. Looking
at Amazon I see they're available, and 2400 dpi is not unusual.
But I rarely use more than 300dpi. Data just doesn't come that
small, even in a photo, that I need 2400dpi. And what would I do
with it? A 3x5 photo becomes many times the size of my monitor
and close to 300 MB.
If/when my current duo fails, I'll probably buy the cheapest
replacement. The current version of my HP Envy is about $100.
But of course it depends on your needs. If I print 30 receipts,
5 contracts and 20 tax forms in a year, my main problem is
not quality. Rather it's how to avoid buying 2 cartridges of
ink every year to only use a small fraction of the content before
it's dried out.
People say I should get a laser printer, but they seem to start
around $250 for B/W printing. Fine for a small law office, but silly
for my need.

Not in my experience. If I'm scanning text for OCR, 300
is good. If I'm scanning a photo to get a digital version,
300 is usually plenty. A typical monitor is 96 dpi display.
So 300 dpi scanning is a 3x copy. A cellphone displays
at greater density, of course, but it's also tiny. So for
most digital uses, over 300 dpi has no value.
What if you want to scan in a tiny postage stamp? OK.
But still, if the detail is not exquisite, and you're not doing
detailed work with the image, then you won't benefit from
high dpi scanning that gives you a 2 foot square image of
a postage stamp.

True, original inks did not dry that much, but replacements were very expensive.
So, be in a hurry to print a CV to mail, and having to spend an hour or

no usage, just power it up and print. Maybe tell it to align first, for better results.

This number seems completely arbitrary to me because given a free
choice, or as free as it can be for anyone, in reality men and women
don't settle into equal proportions in all types of jobs. Maybe about
10% women in electronics *is* the natural balance?
Anyone can be as determined as they want to be. Electronics wasn't a
subject you could study at school in my day, or if it was, our school
didn't offer it.
Are we to assume that women are less interested in things like
electronics or are they less capable of following their own desires if
they happen to be unconventional ones? Can we even question any of this without being labelled with an "-ism" of some sort?
A requirement of my engineering degree was that we undertook a workshop training course.

I think the forgery protection, was a side effect of the
POTS phone system and CallerID. You could tell a fax
had come from Phone Number "x" via CallerID.
Today, you can't rely on that. Not in any way.
As for sending a FAX over VOIP, you can try that at "9600"
baud but not at "14400 Fine". Presumably an aliasing problem.
And without "Fine", it's going to look like shit.

Not exactly an answer, but have you considered just getting
a cheap printer duo?
Each to his own, of course, but my vote is against such devices. I
don't like the idea of combo hardware. If one component fails, you
need to buy another combo unit.
Moreover with a combo unit, you may get a good printer, but a poor
scanner (or vice-versa). With individual units, you can choose the
best of each type or the one of each type that best fits your needs.
A separate printer and scanner is going to use up a lot of desk space.
Yes, and that's a very good point. For some people, it's a very
important point, but not for me; my desk is very large and has room
for both.
And by the way, there are some desks built for computer uses that have
a large drawer made to hold a printer or scanner. My desk has such a
drawer, although I don't use it for that.

In other words, it is possible to create a complete forgery
(remember the Hitler Diaries?) and fax it. What you have at the other
end is a true copy of the document sent. Having been "faxed" does not
make the document any less a forgery.
All you have with a faxed copy is proof that the fax machine was
working at both end. Just as a hardcopy shows that the printer was
working. FIFO. (Fake in, fake out.)

I don't know why FAX is written off. We used to get morning FAX with a lit of overnight faults, you took the sheet off the machine are read. If you were going straight out you could take it with you.
When they stopped, you to wait whilst the laptop started up, find the right page, download and print which all took much longer.
To send a FAX you just put the paper in the machine and often pushed a single button.
I can't see why they cannot make an equivalent using an Internet connection instead of phone line.

There are mail to FAX gateways.
Commercial operations use these, for outgoing FAX. It costs money.
Office FAX machines can also handle incoming FAX
electronically, rather than print all of them.
This allows a human, to sort out the "spam" that
FAX machines receive, and toss away the rubbish.
This might be termed a FAX server. You connect
and see what rubbish pile has arrived. I've never used
one, so don't know the details.
On modern FAX machines, if you do not have electronic
reception, the spammers will run your FAX machine out
of paper. That is how persistent and nasty they are.

The problem is when people assume that a fax is a faithful copy of the original document, free from possibility of forgery/fakery. That used to
be true when the only way to fax was to use a dedicated
scanner/fax-sender and another dedicated fax-receiver/printer. But as
soon as computers started to have dial-up modems which also "spoke" fax,
that illusion was shattered: now it was possible for the document to be
sent without a hard copy of it ever existing, and for the signature to
be a separate scanned image (effectively a rubber stamp signature) that
was pasted onto the document. Likewise the received fax could arrive as
an image file (eg a BMP file), via a fax-to-email gateway such as my ISP
used to offer.
I'm not sure that I agree with Carlos ER's statement that the variety of routes that successive TCP packets are sent would "kill fax". All that
would be needed in a mythical fax-over-TCP protocol would be a sequence number so the packets can be reassembled in the correct order despite
taking various routes to arrive, together with some form of
error-correction to cater for packets getting lost, in the same way that fax-over-voice needs to cater for noise on the line, and to fail
gracefully.
What would kill fax-over-VOIP is the compression algorithms
which are lossy: with voice signals over VOIP, what you receive is a
good approximation of what you started with, but not necessarily a bit-for-bit copy of it. There would need to be a way of fax-over-VOIP disabling the normal compression algorithms that are tuned to voices,
and to use only the lossless compression of the fax protocol itself.

What matters when you went to school, is did you have enough fun.
Did you attend sufficient drinking events ?
That never shows on your transcript.
"Electrical Engineering" would include Power Systems.
"Electronic Engineering" is not likely to include Power Systems.
Not all institutions offer those two degrees, like
at the same time. Only one of those might be on offer.
The course work in Power Systems is mundane, but there
is a metric ton of material to study. My instructor did
not have time to do the Tensor section, before classes ended.

All true, but I don't see how it would be more true or less true for
either boys or girls, so it doesn't explain why they make different
choices. Information about electronics, as with information about
anything else, is equally available or unavailable to everyone.
Some people follow the career choices offered or suggested to them

they're given to study at school), and some people follow their own
interests regardless of whether they have anything to do with school subjects. Some people go with the crowd and do as others around them

Apologies for the cross post, but this is a hardware not an OS or
software question.
I'm at relatives hoping to scan their stuff for the family archive, only
to find that I forgot to lock the transport mechanism of my scanner - a CanoScan LiDE 300 - before packing it for the journey, and further it seems to have been upside down in the car. Not only was the underside
of the glass covered in dust from the ancient documents I've scanned in
the past, but it seems so is the scanner head, because I'm getting
lines, not just specks, across all the scans. I tried dismantling and cleaning it, which has got rid of the specs, but not the lines, and as a result some of the plastic surround no longer locks properly back into
place, though I don't think I broke any catches, certainly I tried to be careful not to do so, and further each scan now pauses one or two times
and then restarts, thus tripling the time taken for each scan.
Can anyone suggest a reliable basic model of scanner which allows one *EASILY* to clean the inside of the glass and the mechanism?
Note:Â This computer is W7 but I have another here with me that is
dual-boot W7/Ubuntu 18. The new scanner could be used with either, I'm
not fussed, just as long as it works!

documents I've scanned in the past, but it seems so is the scanner
head, because I'm getting lines, not just specks, across all the
scans. I tried dismantling and cleaning it, which has got rid of the
specs, but not the lines, and as a result some of the plastic
surround no longer locks properly back into place, though I don't
think I broke any catches, certainly I tried to be careful not to do
so, and further each scan now pauses one or two times and then
restarts, thus tripling the time taken for each scan.
Can anyone suggest a reliable basic model of scanner which allows one
*EASILY* to clean the inside of the glass and the mechanism?
Note:Â This computer is W7 but I have another here with me that is
dual-boot W7/Ubuntu 18. The new scanner could be used with either,
I'm not fussed, just as long as it works!
Thanks for all the contributions. This is the state of play now ...
In the end, in the total absence of anything that could be dismantled
easily for cleaning, I went for a CanoScan LiDE 400, a newer model
than the one I'd already got, on the ground of ease of use, which then
was cheapest in Argos, even after driving to Fraserburgh to collect
it. However that developed stripes in the scan during its first
session of use, leading me to wonder if the stripes in my LiDE 300 had
been there a long time but, due to them visible only on dark source
material, I simply had never noticed them before (they're where the
side arrows indicate, very faint but definitely there, and definitely
from the scanner, as the first test shows; note that each file is
about 13-15MB, so will take time to load):

So the new one went back to Argos, and I got my money back.
So what to try next? As also I've been having problems scanning 120
film negatives and slides, I decided to try and solve that problem at
the same time. However, there is a lack of real choice in the market
- Â most dedicated film scanners don't do film sizes as large as 120,
while most scanners are now multi-function printer/scanner/copier/fax
type of devices. In the end, after much angst about some of the
negative reviews on every even-remotely-suitable model I researched,
and about the cost, I've ordered an Epson V900. According to the
reviews, the hardware is good unless you're pretty unlucky, and
apparently the software is old and clunky, but then so am I, so may be
we'll see get along together! It's going to take an absurd amount of
time to get here, but I'll report back when I've tried it.
I can see the lines, after adjusting brightness/contrast in GIMP.
At the very least, a scanner with digital ICE might reduce some
of the grunge.
But the really important question. Is there really a V900 ?
I thought the V850 was it for them, and the "V900" was some
chit-chat in forums trying to guess a roadmap.
A Google is not finding any retailer-evidence of such an animal.
The V600 would be the cheaper one, with a single lens
instead of the dual lens V850.

Sorry, my mistake, should have been V600! My order has already been dispatched, and I can't afford a V850 anyway, but, seeing as you've mentioned it, how is the second lens utilised, and what practical difference does it make?

It's a slightly higher resolution optical path.
It switches up to a lens that is capable of 6400DPI,
then does the slower scan.
I don't know if there are any pictures of the
actual mechanism.
The V600 uses the same lens for everything.
Be aware that the transparency path on these machines,
is not "bed-wide". On my scanner, reflection and
transmission are bed-wide. I could scan a 8.5x11
transparency from a powerpoint deck if I wanted.
The V600 transmission path, is a few inches wide
(so the slide frame goes in the center somehow).
There may be marks on the deck, that align with the slide tray.
The V850 is wider (to suit the largest format it supports).
Whether it goes out to the very edge, I don't know.
V600 config for scanning paper. Remove the white thing, before the next picture.

V600 scanning negatives. The width of that "window thing", is the scan
width.
The provided media trays, demonstrate the width it scans. No tray will be wider than the window.
https://www.dpreview.com/files/p/articles/1857649076/product/Epson-V600-08.jpeg
The "window" on the V850 is wider.

But the V850 still has that insert-thing for paper scanning.

  ( https://www.northlight-images.co.uk/epson-v850-film-scanner-review/ )
The CCD on the V600 is listed as "1 x"
   https://www.imaging-resource.com/SCAN/V600/V600.HTM
   Photoelectric Drive  12-line Epson Matrix CCD  [really???]
The CCD on the V850 is listed as "6 x" implying two RGB sensors of some
sort.
 (V850) Optical Sensor: Matrix CCD with Micro Lens and High Pass Optics
 (V850) Light Source: White LED, IR LED with ReadyScan LED Technology
You can't believe anything you see in print. Hmmm.
Many scanners do not list the scan time. Only the most optimistic
("typing paper at 150 DPI in 8 seconds") get listed :-) It could
take several minutes to scan a tray of material at 2400.
One spec I was looking at, says 10 milliseconds per row.
Which is 100 lines per second. At 2400 DPI, it takes 24 seconds
to scan one inch. Five inches is two minutes.
Most of these things use stepper motors. so you can't expect miracles.
As far as I know, both use CCD, so should be more forgiving on
depth of field. If they were CMOS, you'd have to "crush them flat" :-)
It really depends on what kind of optics each array (reflection,
transmission
on the V850) is fitted with, as to how much trouble there would be
with depth of field.
The Epson site has spec sheets for both. But as noted above for
the CCD details, it's hard to say what exactly is in there.
I'm not sure how I managed to pick up any attitudes and expectations
about electronics or broadcasting from any of my family members since
none of them knew much about it, or especially cared, and there were
plenty of other interests to choose from amongst my school friends.
If some people do something and some people don't *despite* external influences (or the lack of them) that seems to suggest to me that the differences are to do with the differences between people and nothing to
do with any external influences.
