Correcting A Fault Status Condition - Canon LBP-2000 Service Manual

VI. CORRECTING A FAULT STATUS CONDITION
If the cause has been determined to be a "fault status condition" in relation to the Troubleshooting
Flow Chart (Figure 4-1-1), be sure to go through the following:
6-1. 'E000 CALL FOR SERVICE' (fault in fixing assembly)
'E001 CALL FOR SERVICE' (low temperature error)
'E003 CALL FOR SERVICE' (temperature error)
'E808 CALL FOR SERVICE' (fuser drive circuit error)
Note: If 'E000', 'E001', 'E003' or 'E808' is indicated, the information on the fault in the fixing
assembly is retained in the NVRAM on the DC controller PCB even after the power switch
has been turned off and then on. (Whether or not the code is indicated depends on the
reading of the fixing roller temperature.) If the code is indicated, be sure to clear the fault
information using service mode. (See C. of VIII. in Chapter 1.)
<Possible Causes>
1. The fixing assembly is not properly mounted.
Action: Turn off the power, and correct the mounting of the fixing assembly. Then, turn the
power back on.
2. The connector has poor contact.
Action: Turn off the power, and check the wiring and connector from the power supply PCB/
DC controller PCB to the fixing assembly.
3. The fixing assembly drive circuit on the power supply PCB is faulty.
Action: Replace the power supply PCB.
4. The DC controller PCB is faulty.
Action: Replace the DC controller PCB.
6-2. 'E011 CALL FOR SERVICE' (main motor fault)
<Possible Causes>
1. The connector of the main motor (M101) drive signal has poor contact.
Action: Correct the connection of the connector J903 of the main motor and the connector
J106 on the DC controller PCB.
2. The main motor (M101) is faulty.
Action: Replace the main motor.
3. The DC controller PCB is faulty.
Action: Replace the DC controller PCB.
