I throttled my 550 MHz computer back to a 333 MHz to match my other machine and
|
|
<BR>
|
|
isolated the scanner on the SCSI buss. I ensured both the scanner and the SCSI
|
|
<BR>
|
|
interface were the only terminated devices on the buss. I also scanned with
|
|
<BR>
|
|
two different cables. Still no improvement.
|
|
<BR>
|
|
<P>Any suggestions on where I can go from here? I think I've ruled out a hardware
|
|
<BR>
|
|
problem.
