Procedure
WARNING
Switch off the electricity to the machine. Disconnect the power cord from the customer
supply while performing tasks that do not need electricity. Electricity can cause death or
injury. Moving parts can cause injury.

WARNING
Do not repair or install a new fuse F01 on the power supply unit 1. Repairing or installing
a new fuse can cause overheating and a risk of fire.
WARNING
Do not repair or install a new fuse F1 on the power supply unit 2. Repairing or installing
a new fuse can cause overheating and a risk of fire.
NOTE: The main PWB has test points. The location of the test points is shown on the Main
PWB PJ location illustration.
NOTE: Throughout this procedure, where further steps require the reconnection of a compo-
nent, ensure they are reconnected before performing the next step.
Refer to Wiring Diagram 1, Wiring Diagram 2, Wiring Diagram 3, Wiring Diagram 4, Wiring Dia-
gram 5, Wiring Diagram 6, Wiring Diagram 7 and Wiring Diagram 8. Perform the following:
1. Ensure the supply voltage is correct. If possible, connect the machine to a known good
power supply. If the customers power supply is faulty, inform the customer.
2. Disconnect the power cord from the power outlet and the machine. Check the continuity
of the power cord. If necessary, install a new power cord.
3. Refer to Wiring Diagram 1. Disconnect CON01 on Power Supply Unit 1. Check for AC
supply voltage between pins 1 and 2 on the connector. If necessary, install a new main
power socket, PL 1.10 Item 6.
4. Check the fuse F01 on power supply unit 1. If necessary, install a new power supply unit
1, PL 1.10 Item 3.
NOTE: Fuse F01 is not spared.
5. Disconnect CON7 from Power Supply Unit 2. Check for AC supply voltage between pins 1
and 2 on the connector. If necessary, install a new power supply 1, PL 1.10 Item 3
6. Remove the fuser, REP 10.1. Check for continuity across the fuser heat roll. Install new
components as necessary, PL 10.25 and PL 10.26.
NOTE: A cold fuser heat roll has a resistance of approximately 16.5 ohms (220V/240V) or
2 ohms (110V).
