Canon E064 High-Voltage Error Diagnosis Guide

CHAPTER 6 SELF DIAGNOSIS

E064

0000	The presence of a high-voltage error is communicated by the composite
	power supply PCB. (The output for primary charging, developing, or trans-
	fer has deviated from a specific level of voltage.)
Main cause	The contact has poor connection. The wiring is faulty. The composite power
	supply PCB is faulty. The DC controller PCB is faulty.
Action
1. Contact
	Is any of the contacts of the primary charging roller, developing assembly,
	or transfer charging roller soiled? Or, is there poor contact?
	YES: Clean the contact, and set it once again.
2. Wiring
	Is the wiring between the contacts for the following normal: DC controller
	PCB (J301), composite power supply PCB (J136), primary charging roller,
	developing assembly, transfer charging roller?
	a. DC controller PCB (J301) <-> composite power supply PCB (J136)
	b. composite power supply PCB (J130-7) <-> primary charging roller con-
	tact
	c. composite power supply PCB (J130-1) <-> developing assembly contact
	d. composite power supply PCB (FT133) <-> transfer roller contact

NO: Correct the connection.

3. Composite power supply PCB, DC controller PCB

Try replacing the composite power supply PCB. Is the problem corrected? YES: Yes.

NO: Replace the DC controller PCB.
