> Hi,

> 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 [1] 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
> argument".
>
> I have made several test scans and uploaded the results into a folder
> at the university, please find them here [2]. 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".
