plustek: Thread: CanoScan LIDE 20

Hi:
I have used plustek-sane-0_44_7 with this scanner. It has a product id of 
0x220d as the CanoScan N670U.

It works with some problems:

1- Getting  ready to do a preview the scanning head moves to the start 
position but the motor continues to work as if the scanner can't tell that 
the head is there already.  This doesn't happend at regular scanning.

2- The  scanned image (8 bit color) has a pink tone that I have not been able 
to correct with any of the contrast, brightmess or gamma corrections.  If I 
scan a "blank" the pink is there in sort of diagonals bands.

Any suggestions or things I can try?

thanks

Andrés Escallón

Thanks for this report.

I'm afraid, that there' currently nothin you can do.

What's the status on the drivers for CanoScan LiDE20? When I try to scan
images they do get awfully pinkish.

The status is still the same, I've rewritten some code and
cross-checked with other apps - no success so far.
I'm still fighting...

This is quite normal.
Set these values in the "plustek.conf" file (remove the "-1" values)

option red_gain   1
option green_gain 37
option blue_gain  32

Quality will still be low, but the colors are recognizable.
