Canon ir 8500 error code e000677 5802 - Canon Office Equipment & Supplies

SOURCE: Canon IR 8500 Error code E000069-0000

You have a high-voltage leak to the transfer corona. This could be due to several different things, usually it's a dirty corona, maybe excessive dust or toner in the corona assembly. Toner conducts electricity and can leak voltage from the transfer corona to the frame. It may also be the "end-blocks," the thing in the back of the machine into which the transfer corona plugs when you close the drawer and lift up on the green handle. These crack and can cause intermittant failure.
I would start by taking a can of air and thoroughly blowing out the corona assembly and see what that does for you...

E064 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.
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 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.
