Any help is appreciated,

Is the scanner on the same SCSI bus as a disk drive with a swap file?
I have run into a problem before where scanners which do not
disconnect during calibrations or longer scans will cause swap file
I/O to timeout. The swap file is fairly intolerant of these delays
(I'm trying to remember, but it was about 3 seconds I think). If that
I/O times out then a full reset of the SCSI bus will occur and your
scanner I/O will be tagged as timed out. Because you don't really
know when the swap file will be hit, the problem will be intermittent,
etc.
So, what do you do? Make sure the scanner supports disconnects on
*ALL* its operations (and make sure you haven't disabled disconnects
in Adaptec's SCSISelect). If it doesn't, then your only option is to
put it on a different SCSI bus from the hard drive and complain to the
vendor about their firmware.
