last time I wrote to this list it was my fault not to read the fine
manual about SCSI settings. Now I tried to do it all right:
- Kernel 2.0.28
- ncr53c8xx.{c,h} revision 1.18f (taken from linux-2.1.36)
- no disconnect
- no tagged command queuing
- 128k SCSI buffer
- sane-0.57
The scanner is a MFS-12000SP which says
Host: scsi1 Channel: 00 Id: 06 Lun: 00
Vendor: SCANNER Model: Rev: 1.00
Type: Scanner ANSI SCSI revision: 01 CCS
The scanner is the only device connected to an Asus SC-200.
(The disks etc. use the NCR on the mainboard).
Now if I do a
scanimage -d mustek:/dev/scanner --mode Color -x95mm -y200mm --resolution
300
I get an image of size 7939717 with header
P6
# SANE data follows
1120 2363
=2E..
The problem is that about every 128kBytes in the image 1 or two scan
lines of garbage seem to be added (I think sometimes lines are
missing, too). I could send excerpts from the image if it helps. The
--backtrack option doesn't change anythink, in fact the scanner always
backtracks (as I can tell from the movement of the light shining
through).
The distorted lines also appear in modes other than Color. I'm pretty
sure (90%) that I had a similar distortion when I once had the scanner
connected to the NCR53C400 card.
Needless to say, it works ok with windows :-(
So, what else can I do?
Best regards
Stefan
