Hi, I recently purchased a Canon LIDE 220 as it was claimed to be support by sane. I put the USB code (04a9:190f) into the Scanner Search Engine at the sane.org and it yielded this page which says support is complete.
http://www.sane-project.org/cgi-bin/driver.pl?manu=&model=&bus=any&v=04a9&p=190f It was not found by the sane shipped with Ubuntu 15.04, so I installed this ppa: ppa:rolfbensch/sane-git And updated. The scanned was then recognized by the xsane, et al. It mostly gave errors alluding to an invalid device. When it did try to scan, the head would go to the far end and required unplugging the USB cable to get it to stop banging at the end. Sometimes, not often, it would work fine. I did a bunch of reading and I was able to fix things by setting sane debug variables. One site suggested this and it worked: export SANE_DEBUG_GENESYS=255 export SANE_DEBUG_GENESYS_LOW=255 export SANE_DEBUG_GENESYS_GL124=255 scanimage -d genesys -l 0.0 -t 0.0 -x 90 -y 140 --resolution 1200 --mode Color >scan.pnm 2>scan.log I've narrowed it down to just export SANE_DEBUG_GENESYS_LOW=8 >From my reading, I believe there is a race condition more exposed by faster hardware. I have new, fast hardware. My libsane version is 1.0.25-git20150612-vivid0 on Ubuntu 15.04. At this point the scanner is working reliably with no bad behavior. I am having one issue which seems like a driver bug. Using Xsane through gimp, set to grayscale 300 and 1200 dpi, the scan is fine. At 600dpi the pixel dimension of the scan is correct, but the lengthwise aspect ratio is stretched so that only maybe 2/3 of a letter size is actually scanned and it's stretched to letter size. The scanner head only moves across the top ~2/3 of the scanned page. Let me know what other info I can provide, or if there's already an answer that I've missed, I'll be glad to be pointed in the right direction. Thanks, John
