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:
https://www.dropbox.com/sh/xmd5axjxn0n07z7/AADMt_fuQ98i6m3aZbSKPNbJa?dl=0
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
