I have come across an "HP ScanJet G2410" scanner (03f0:0a01) at work
which I have connected to my Debian Squeeze box to scan some pages (I
was tired of having to scan under Windows where the scanner usually is
connected at my work place).
Anyway, since this scanner is not yet fully supported by SANE, I have
decided to test as much as possible and report the results since the
SANE backend listing at  still lists the scanner as "Untested".
Basically, the scanner works perfectly when scanning lineart or
greyscale which is I what I need most of the time to scan
documents. However, only scans with 300 dpi work fine, all other
resolutions either produce scrambled results (50, 100, 600 dpi) or
don't work at all (75, 150, 1200 dpi), error message "Invalid
I have made several test scans and uploaded the results into a folder
at the university, please find them here . I am also going to place
a reference scan at 300dpi, color with the Windows software since
scanning color images with SANE results in errorneous colors.
Since scanning documents with lineart and greyscale at 300dpi works
flawlessly, the status of this scanner should be changed to "Basic".
Resolution Color Mode Works?
50 line art scrambled output
50 grey scale scrambled ouput
50 color scrambled output
75 line art NO, ("Invalid argument")
75 grey scale NO, ("Invalid argument")
75 color NO, ("Invalid argument")
100 line art scrambled output
100 grey scale scrambled output
100 color scrambled output
150 line art NO, ("Invalid argument")
150 grey scale NO, ("Invalid argument")
150 color NO, ("Invalid argument")
300 line art YES, output OK
300 grey scale YES, output OK
300 color YES, but wrong colors
600 line art scrambled output
600 grey scale scrambled output
600 color NO, scan takes forever
All scans were made with 8 bit depth. Results were the
same for 16 bit depth.
I wasn't sure which debug information to provide, so I just
paste the verbose of scanimage and sane-find-scanner. If you
need anything else, please let me know.
