Canon ir2870 show error code E000064-0003
The presence of a high-voltage error is communicated by the composite power supply PCB (The output for primary charging, developing, or transfer has deviated from a specific level of voltage)
The contact has poor connection. The wiring is faulty. The composite power supply PCB is faulty. The DC controller PCB is faulty. proce
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 contact 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.
