thank you for the advice Brian.

SANE is not finding my scanner now. It worked fine before I scanned something with windows (previously mentioned). My web search revealed that in troubleshooting this I need to enter two commands, sudo sane-find-scanner & sudo scanimage -L:

sudo sane-find-scanner

[sudo] password for bmike1:

# sane-find-scanner will now attempt to detect your scanner. If the

# result is different from what you expected, first make sure your

# scanner is powered up and properly connected to your computer.

# No SCSI scanners found. If you expected something different, make sure that

# you have loaded a kernel SCSI driver for your SCSI adapter.

# No USB scanners found. If you expected something different, make sure that

# you have loaded a kernel driver for your USB host controller and have setup

# the USB system correctly. See man sane-usb for details.

# Not checking for parallel port scanners.

# Most Scanners connected to the parallel port or other proprietary ports

# can't be detected by this program.

and

sudo scanimage -L

device `hpaio:/usb/Photosmart_C7200_series?serial=MY7A2G42SW04YG' is a Hewlett-Packard Photosmart_C7200_series all-in-one

While 'xsane -L' recognizes the device SANE seems not too. I would follow further advice from the support thread where I got these commands but my computer sees it but won't use it plus my scanner was working!

I've always like xsane, btw SANE (Scanner Access Now Easy) is the drivers that pretty much everything in Linux uses for it's backend, most frontend programs just show less options in order to make scanning easy and can hide increasing the resolution of the image.

XSANE exposes the maximum amount of options, but that also makes it more difficult to use. It does have some really nice options that aren't found in many other programs like being able to set zones on your scanner so that you can scan multiple images or pages at once and xsane will automatically chop them up into seperate images for you. That makes bulk scanning much faster.

One other thing you might want to try if you are bulk scanning books is to just use a digital camera. A digital camera can take pictures of the pages as fast as you can turn the page and most cameras these days have enough DPI that that you will have no problem reading them later.

To increase the quality of the photo, find a piece of glass. I ended up temporarily robbing one from a picture frame. Then use the glass to press the pages flat for the camera. You'll also want a light or 2 to get good results. Make sure that you light the book from the sides and not try to get it straight on or you'll get a ton of glare.

Once you are done, there are some utilities that can increase the quality of your scanned or photographed images. Unpaper is one that comes to mind. It can help make the image look even more flat, especially towards the spine of the book.

I've been using gscan2pdf for a long time. I have been considering the
poor resolution as the breaks of the game. I recently resolved to try to
fix it because I was scanning my computer manuals in. I fiddled with
some stuff but no improvement. I then thought it might be gscan2pdf so I
started another scanner. I picked SANE and while the scan was much
slower the resolution was not much better (I 'm sure the program isn't
called SANE but whenever I try to open a scanner program now I am told
"Sorry. No devices found." The second program I used is found by
clicking "Acquireimages"). So I thought it was a scanner issue or a
computer issue; so I shut Linux down and started Windows. Well, with the
Windows7 included scanner program the scan was slower than with
gscan2pdf (default settings) but not slower than with SANE and the image
was clear. In fact I was able to zoom in 200% and while it was not
crystal clear it was very much legible while a Linux zoom of 100%
produced a practically illegible document.
