Troubleshooting and test switches
For normal scanner use, verify that switches 5, 6, 7, and 8 (troubleshooting and
test switches) are OFF.
Switch 5. SCAN-SCSI (connectors 0A and 0B):
When ON, it disables
SCAN-SCSI synchronous transfer mode (reverts to asynchronous transfer).
Use this mode only for testing because it slows down the scanner.
Switch 6. COPY-SCSI (connector 1):
When ON, it disables COPY-SCSI
synchronous transfer mode (reverts to asynchronous transfer). Use this mode
only for testing because it slows down the scanner.
Switch 7. Force boot start up:
If a malfunction occurs during an update of the
scanner firmware, this switch forces the scanner into firmware boot mode,
enabling you to download the firmware again.
Switch 8. Continuous test mode:
You should never use this switch, which is
reserved for testing only by qualified maintenance personnel. The scanner is
inaccessible.
