Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

My Epson scanner died and I replaced it with a Canon Canoscan LiDE 400 because the SANE supported devices page says it's completely supported and uses the pixma backend. The SBo pixma and cnjifilter2 packages do not support his printer.
I downloaded and built Canon's source code for this model but it's a stand-alone program, not a loadable module that xsane can use. I'm waiting for someone on the sane-devel mail list to respond to my post. In the meantime I would like suggestions for installing a driver that can be seen by xsane.
I have a Canoscan Lide 25 and it runs on the plustek driver which is part of sane. I have the /etc/sane.d/plustek.conf set to autoscan for usb and it just picks it up.
These old unit "plug and play" reports probably are not helping much (I was watching the SBo list via my eMail), but my LiDE 30 works without extra drivers. I am also using simple-scan.
Isn't the pixma included in SANE?
usr/lib64/sane/libsane-pixma.la
usr/lib64/sane/libsane-pixma.so.1.0.25
etc/sane.d/pixma.conf.new
The above is taken from SANE version 1.0.25 for Slackware 14.2 (sane-1.0.25-x86_64-2.txz)
For current:
version 1.0.28 (sane-1.0.28-x86_64-1.txz)
etc/sane.d/pixma.conf.new
usr/lib64/sane/libsane-pixma.la
usr/lib64/sane/libsane-pixma.so.1.0.28
sed -i '/canon_dr/a\canon_pixma' /etc/sane.d/dll.conf
# or this command
echo "canon_pixma" >> /etc/sane.d/dll.conf # for activate the backend in sane
# look at https://github.com/Ordissimo/scangearmp2 (For all distributions you need to activate the backend :)
That explains why your LiDE 400 isn't recognised since 14.2 has only release 1.0.25. The good news is that 1.0.28 is the release being used in -current. I don't recommend using the supplied 1.0.28 package directly in 14.2 since there may be some runtime problems linking with libraries available in -current but not in 14.2. However you can just recompile -current's 1.0.28 SlackBuild in 14.2 (it works - I just tried it) and then upgradepkg to the resulting package (by default, it'll be left in /tmp).

Reason: Add lURL
An issue with the Canon came up today. Once or twice both xsane and scangearmp2 found the scanner and scanned the page. But, the paper was not properly adjusted so I tried again. Now xsane cannot communicate with the scanner (I/O error) and scangearmp cannot find the hardware.
lsusb, sane-find-scanner, and scanimage -L all find the scanner.
Is there a way to test whether the hardware failed already? There's nothing to turn on (the unit is unlocked) and the USB cable is properly attached at both ends.
I need to scan a document and have no more ideas of what to do.
I"m not a printer specialist so no words of particular wisdom from me. In that sort of situation I would try rebooting the machine and hope for the best.
This is just another anecdotal comment but I have a CanoScan LiDE 110 that has always worked out, without any driver/firmware added, using xsane on my 14.2 x86_64 PC.
The only time I can recall xsane having a problem detecting the scanner is when I plugged it into a USB extension adapter/cable, instead of just using a USB port on the PC. Maybe something to consider if you're using something like a USB hub.
