Hello everyone!
I've just compiled and installed Sane 1.0.3 and Sane Umax 1.0.3 build 24
on a machine running Linux with kernel 2.4.0 (RedHat 7.0).
Scanning with my Umax 610S works fine in both colour and grayscale at
resolutions up to 300 dpi, but _not_ in lineart mode at resolutions
greater than about 150 dpi. When I try to scan an image in lineart mode at
this resolution (>150 dpi) the scanner first stops half-way and then
return to its initial position.
Does anyone know of a solution to this odd behaviour?
The scanner is attached to a Tekram DC390 card (the one with the AMD
chip) which uses version V2.0e4 of the tmscsim kernel module.
Here's some debug output while scanning a lineart image:
