Hello everyone!
|
||
<BR>
|
||
<P>I've just compiled and installed Sane 1.0.3 and Sane Umax 1.0.3 build 24
|
||
<BR>
|
||
on a machine running Linux with kernel 2.4.0 (RedHat 7.0).
|
||
<BR>
|
||
<P>Scanning with my Umax 610S works fine in both colour and grayscale at
|
||
<BR>
|
||
resolutions up to 300 dpi, but _not_ in lineart mode at resolutions
|
||
<BR>
|
||
greater than about 150 dpi. When I try to scan an image in lineart mode at
|
||
<BR>
|
||
this resolution<6F>(>150 dpi) the scanner first stops half-way and then
|
||
<BR>
|
||
return to its initial position.
|
||
<BR>
|
||
<P>Does anyone know of a solution to this odd behaviour?
|
||
<BR>
|
||
<P>The scanner is attached to a Tekram DC390 card (the one with the AMD
|
||
<BR>
|
||
chip) which uses version V2.0e4 of the tmscsim kernel module.
|
||
<BR>
|
||
<P>Here's some debug output while scanning a lineart image:
