VI. MALFUNCTION STATUS TROUBLESHOOTING

Perform troubleshooting according to the malfunction diagnosis flowchart (Figure 4-1-1). If an
“malfunction status” is found, the defective part must be located and rectified by the following
procedures.

VI-1.

Scanner motor/BD failure

<Possible causes>

1) The laser shutter cannot open due to the damaged claw of the cartridge cover.

Action:

Replace the cartridge.

2) The contact in the connectors on the laser scanner unit is poor.

Action:

Reconnect the connectors J801 and J802.

3) Poor contact in the connector on the intermediate PCB

Action:

Reconnect the connectors J901 and J905.

4) Poor contact in the connector on the engine controller PCB

Action:

Reconnect the connector J-907 on the intermediate PCB.

5) The laser/scanner unit is defective.

Action:

Replace the unit.

6) The intermediate PCB is defective.

Action:

Replace the intermediate PCB.

7) The engine controller PCB is defective.

Action:

Replace the engine controller PCB.

VI-2.

Fixing unit failure

<Possible causes>

1) Broken wired or short circuited main thermistor.

Action:

Turn OFF the power and remove the fixing unit from the printer. Measure the
resistance between the connectors J206-1 (GND) and J206-2 (FSRTH) on the fixing
unit side. If the resistance is not within the range from about 370 kΩ to about 520
kΩ (room temperature of 20°C), replace the fixing film unit.

2) Broken wired or short circuited sub thermistor.

Action:

Turn OFF the power and remove the fixing unit from the printer. Measure the
resistance between the connectors J206-3 (FSRSTH) and J206-4 (+3.3V) on the fix-
ing unit side. If the resistance is not within the range from about 370 kΩ to about
520 kΩ (room temperature of 20°C), replace the fixing film unit.

3) Broken wired heater / blown thermal fuse.

Action:

With the fixing unit removed form the printer, if there is no conductivity between
the connectors J102-1 (ACH) and J102-2 (ACN) on the fixing unit side, replace the
fixing film unit.

4) The engine controller PCB is defective.
