For People looking for the answer: google "PDF escape", goto the site, upload your pdf, goto the "Page" tab, then "More" and then "deskew" and you use the line to align your skewed document by 10th's of a degree. It worked great for me!

Finereader software will do the trick

Yes Auto Straightener from sabsoft.com does a great job of straightening pdf files automatically but does not allow the user to rotate by degree.
Make sure to click on pdf straightener in the program because there is 2 options ...scanned page or scanned pdf

What I do is super simple which is I use Irfanview for everything above.
1. Irfanview freeware is the twain scanner software
2. Irfanview has the F12 menu (which is the "Paint" menu)
3. On that "Paint" menu is a straightener tool

I just used PDFEScape Free Online Tool.
Once you upload the document, they have a tool called "descew" in the bottom right on their tools bar, where you click and drag in the direction of the rotation, and it asks you for the degree of rotation.
Easy to tweak and save.

Try cleaning the rollers under the top left side of the printer.

It can be done with the popular free image editor "IrfanView" , the program is simple to use & is quickly opened unlike Gimp. Go to the "Image" menu then select "Custom /Fine rotation" . The angle of rotation can be adjusted with the up/down arrows
or enter a value direct into the box. For increments of less than 1 degree you need to enter the value direct into the box as the arrows only adjust by a value of 1 whole degree. Use trial and error with the values to get the rotation your happy with,
you can then save as an image or a pdf. It's been my go-to app for all simple image editing for a long time.

Not really. I always do it that way (sing GIMP or similar), because I
often need to use the image in multiple circumstances, so a JPEG image
is much more useful. I can use it in a PDF when I need to (like as an illustration in a document). I've never really understood why a scanner
would want to create a PDF direct, as it's just a wrapper round the JPEG.

That's an interesting observation, particularly since I scan 8.5x11 pages.
o I use Irfanview to scan pages through the printer document feeder

I typically save that result as a PDF.

Based on what you said above...

I didn't know that the scanner software creates the JPEG first.
o And only after creating the JPEG does it save to PDF.

I figured the scanner software made the image in its own internal format.
o Which, for Irfanview, could be JPEG for all I know (as I don't know).

Does this imply that scanning & then saving as a JPEG results in better
quality than scanning and then saving the document as a PDF?

That would really depend on the software settings. I don't know what compression PDF applies to embedded JPEGs. My software delivers the raw, uncompressed data for saving, so the files are huge, but every dot is
there.

JPEG files are usually already compressed. Running a compression
algorithm on them again probably won't compress them any more (and might
even make them bigger).

As far as I understand it, PDF is just a wrapper around many formats,
including JPEG, PNG, etc. The only things which are "native" are fonts,
text, and vector graphics. But that's just the bits I use; PDF can do
lots of other things.

I figured the scanner software made the image in its own internal format.

I think the scanner's internal firmware does indeed use its own format
(HP hardware has its own internal language, so do other manufacturers).
But what format the data is in during its transfer from scanner to
software I have no idea.

Which, for Irfanview, could be JPEG for all I know (as I don't know).

Desktop software probably lets you pick (somewhere) what format to save
the file as. I use XSane which does this: http://www.silmaril.ie/downloads/xsane-settings.png

That would really depend on the software settings. I don't know what compression PDF applies to embedded JPEGs. My software delivers the raw, uncompressed data for saving, so the files are huge, but every dot is
there. Typically I then need to edit the file to correct alignment,
colour, and crop, so I then save uncompressed if it's for print
publication (full-resolution, best quality, but still huge), or 50% compression, which is much smaller, lower resolution, but still
perfectly acceptable for other applications.

The real advantages of a PDF are:

• you avoid the small PDF wrapper overhead
• many computer users don't know what to do with a JPEG (weird when
you consider that's what their camera produces)
• you can put multiple images into a single PDF
• you can create a PDF via WP or DTP software so you can have text
and images combined

If you have a workflow that works, I'd stay with it.

Right. As I don't always want JPEG (some clients use TIFF, and some
prefer PNG for web images), I set XSane to send the raw data (probably
PBM or something internally).
