[sane-devel] CanoScan LiDE 220 can't scan dpi over 1200

[m***@bitdweller.com]

Hey folks,

I just bought a CanoScan LiDE 220. Unfortunately scanning with 2400 or 4800
dpi doesn't work as claimed on your website. scanimage just hangs, not
printing any errors and the sensor doesn't move an inch.
Scanning with 1200 dpi works fine though.

$ scanimage -V
scanimage (sane-backends) 1.0.27; backend version 1.0.27

I appreciate any help.

Best regards,
Martin

Hmm, can confirm, it scans some portion of the image and then hangs. I
think the official software on Windows doesn't support full-page scans
at 2400dpi or greater. It does work if you limit the scan to an area.

Not sure what should be done about this, I don't think there's a
standard way to expose constraints like this to scanimage (but I'm not
sure!).
