[sane-devel] Canon Lide 220 problems?

[kamp000x at arcor.de]

Hi,


I have a new Canon Lide 220.


If I try to scan a 150 dpi grey file, the output is unreadable.

150dpi color is ok

300 dpi grey is ok


an example:

The scanner is doing on any scan a calibration (?) or something, by
driving a few centimeters backwards and forwards before scan.

Sometimes I am hearing some rattle or scratching while scanning, I think
the rail is running too far.


I am REALLY worried about this, but I did not notice these problems on
windows.

Are these known problems on sane?



Thanks in anticipation
