Hello, I've just bought a Canon Lide 220 scanner but I can't make it work at 2400 or 4800 dpi. The scanner is supported 100% from 75 to 4800 dpi as of http://www.sane-project.org/sane-mfgs.html#Z-CANON. I'm using Ubuntu 19.04 and sane 1.0.27. Tried using simple-scan and genesys library on Gimp (2.10.8), if resolution is 2400 simple-scan freezes same thing on GIMP from 1200dpi and up. I need 2400 or 4800 dpi scan of little areas (2cmx2cm) of documents. Can anyone help me? Thanks. --
Marco.
