Remedy
Firmly connect both plugs of the power cord.
Use only the rated supply voltage.
Check the power supply.
Remedy
Firmly insert the cable's connectors until they
lock into place.
Change the SCSI transfer rate (Maximum Sync
Transfer Rate) to 10 MB/s. For details, refer to
the SCSI adapter instruction manual.
Confirm that there is no fault with SCSI cable
connectors (broken or bent pins).
Fully insert the SCSI cable until it locks.
If the scanner will serve as a terminal within the
network configuration, set Bit 4 of the scanner's
DIP switch to enable the internal terminator
function.
Set the scanner's ID number to one that is different
from other devices in the network (see Section 3.4,
"Setting the ID Number").
Use a SCSI cable that is no longer than
3 meters.
