2.The laser drive signal line connectors are loose.

Action: Reconnect connector J1001 on the laser driver PCB, and connector J202 on the DC controller PCB.

3.The laser/scanner unit is defective. Action: Replace the laser/scanner unit.

4.The DC controller PCB is defective. Action: Replace the DC controller PCB.

VI-6. "12.1 ERROR MOTOR CALL FOR SERVICE" Faulty main motor "12.2 ERROR MOTOR CALL FOR SERVICE" Faulty main motor

<Possible causes>

1.The main motor drive signal line connectors are loose.

Action: Reconnect connector J12 of the main motor and connector J218 on the DC con- troller PCB.

2.The door switch on the switch/sensor PCB is defective.

Action: Remove connectors J205 and J221 on the DC controller PCB. If J205-3 (+24V) and J221-1 (+24VB) on the cable side do not conduct when the door switch (SW1401) is ON, replace the switch/sensor PCB.

3.The main motor is defective.

Action: Use the printer driver tester to rotate the main motor. If it does not rotate, replace it.

4.The DC controller PCB is defective. Action: Replace the DC controller PCB.

VI-7. "13.1 ERROR FAM 1 CALL FOR SERVICE" Electrical unit fan (FM3) failure

<Possible causes>

1.The FM3 drive signal line connector is loose.

Action: Reconnect connector J210 on the DC controller PCB and connectors J12 and J13.

2.The electrical unit fan is defective.

Action: Disconnect connector J210 on the DC controller PCB. Turn the power switch ON and measure the voltage between connector J210-1 (FAN3D) and J210-3 (GND) on the DC controller PCB. If the voltage changes from 0 to more than 18V, replace the electrical unit fan.

3.The DC controller PCB is defective. Action: Replace the DC controller PCB.

VI-8. "13.2 ERROR FAM 2 CALL FOR SERVICE" Power supply fan (FM2) failure

<Possible causes>
