50 Troubleshooting
Cause The scanner's SCSI ID is identical to the SCSI ID of
another device.
Action Check the SCSI IDs of all SCSI devices connected to the system
and set a unique SCSI ID for the scanner.
Cause The terminator is not set correctly.
Action Connect a terminator to the SCSI device that is at the end of the
SCSI daisy chain. If the SCSI device has a built-in terminator
function, enable the terminator.
Cause The PC was turned on before the scanner.
Action Shut down both the PC and the scanner, and then turn the scanner
back on, followed by the PC.
Cause The scanner is not on.
Action Refer to the previous section, "The scanner does not turn on," and
check to see if the scanner is on. If the scanner is not on, shut
down the PC, then turn the scanner on first, and then the PC.
Cause The SCSI host adapter is not compatible with the scanner.
Action Use a SCSI host adapter that is compatible with the scanner
driver and your application software.
Cause In Windows NT 4.0 Workstation, Windows 2000
Professional or Windows XP, the ASPI manager has not
been installed correctly.
Action Following the instructions in the SCSI host adapter instruction
manual, install the ASPI manager and then start up the ASPI
manager.
