[sane-devel] Microtek SlimScan C3, output always a black image

[Karsten Festag]

Hi Jose,

please look into your BIOS and make sure the parport mode is set to EPP, not 
ECP! I heard several times that this is the cause for stretched or shifted 
image lines.

By the way: switching off the backend calibration has a negative side effect: 
you will probably see fine vertical stripes on your scanned images. Normally 
the backend calibration gets rid of it, but it looks like we have to find the 
bug in the calibration code so that it works with your scanner. Please tell 
me if we shall do some work in this direction - I'll need some testing work 
on your side to achieve this.

Could you please tell me what error message appears if you use the '-y20' 
option to generate a logfile?

Karsten
