IMPORTANT SAFETY NOTICES

2. The wall outlet should be near the scanner and easily accessible.
3. The output voltage of the PSU (Power Supply Unit) can be either 100 ~ 120 Vac or 220 ~ 240 Vac, without any adjustment. Make sure that the above voltage is used.
4. The power cord should be an approved type, in accordance with the regulations for the country in which the scanner is used.
5. The use of cables other than the shield I/O cables or specified equivalents will invalidate the certification of this scanner and may cause interference levels which exceed the limits established for this equipment.
6. When keeping used lithium batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat buildup.
Lithium Batteries (Memory Back-up)
!
CAUTION The danger of explosion exists if a battery of this type is incorrectly replaced.
Replace only with the same or an equivalent type recommended by the manufacturer. Discard used batteries in accordance with the manufacturer’s instructions.
Maintenance Information
The user’s manual explains how to use and maintain the scanner. Before performing the maintenance, read the user’s manual.

Conditions Symptoms Possible cause
The sensor does not detect the scanner.
When the switch on the machine is turned on
1. The sensor is off and it will not turn on—even if the scanner moves to the left of the 472 mm mark.
Home position (HP) error
NIC SC error SC error at NIC ☛ 5.2.2 NIC Error log descriptions
2. The sensor is on and will not turn off. Even if the scanner moves to the right of the
115.6 mm mark.
When the machine usually works.
1. The sensor does not turn off, even if the scanner is scanning a document in AD F mode.
2. The sensor does not turn off, even if the scanner is scanning a document in boo k mode.
3. The sensor does not turn on, even if the scanner is moved back to the home position.
• Check the scanner lock.
• Replace the HP sensor.
• Replace the scanner motor.
• Check the scanner wire.
• Check the harnesses betwee n

4.1.4 IEEE1394 BOARD (OPTION)

If there are problems scanning using the IEEE1394 interface, check the following.
• Use Windows 2000 with service pack 1.
• Check to see if there is a loop some where in the network. IEEE1394 networks
must be a chain or branched chain.

5.1.1 DIP SWITCH COMBINATIONS

After changing the DIP switch setting, either switch the power on and off, or press the reset switch.
If you change the position of the SCSI ID rotary switch during these tests, be sure to put it back to the original position once you have finished.

NOTE: When SCAM function is enabled, this machine is automatically given an
SCSI ID. This prevents you from daisy-chaining other peripherals with the scanner. If you wish to attach multiple components, disable SCAM and set the SCSI ID at the SCSI rotary switch (☛ Table A: Normal mode).
