Power supply voltage error (high-voltage error)
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.)
Main cause: The contact has poor connection. The wiring is faulty. The composite power
supply PCB is faulty. The DC controller PCB is faulty.
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.
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?
NO: Replace the DC controller PCB.
