Hi,

I'm experiencing similiar problems with an OP96000P. 
--mode=gray,halftone,binary is working.
--mode=color isn't . Except from some special cases

Anything higher than resolution 125 doesn't work:

export SANE_DEBUG_PLUSTEK=12
scanimage --mode color --resolution 150 -x 215 -y 297 -v --format=pnm > /tmp/out.pnm
2>scan.log

will exit with an error message.

I'll attach scan.log to the end of this message.

I checked the hardware with win95, which seems to work.

My setup is the following:

linux-2.4.3-pre4
sane-1.0.4
plustek-sane-0_38_24  (I also tried 0_37_23)


I tried preinstalled sane104.rpm, also. I compiled sane1.0.4 together
with plustek-sane and plustek_driver. Everything could be compiled
with no errors and the driver could be loaded with no errors.

I wonder if the 24 bits/pixel mode conflicts with
the scanners 30bit capability, but this
might just be my misunderstanding something.

I found that
scanimage --mode color --resolution 300 -x 215 -y 2 -t X -v --format=pnm >> /tmp/out.pnm
with X=0,294,2 works ... but no way with --resolution 600 .

Thanks for looking into this
