[Error Code] E065-0001/E068-0001 on Canon IR Adv 6075

[cobra]

I am working on this Canon IR Adv 6075. The first error was E065-0001. I replaced the Primary Charging assembly but error remains. I removed and clean the Primary Grid High Voltage connector. Check all the connectors in the High Voltage Unit. Now the error becomes E068-0001. Clean the Pre Transfer High Voltage connector but error remains. I'm inclined into replacing the Pre Transfer Charger Assembly. I have cleaned and checked the Pre Transfer Assembly and it looks ok. Any ideas? Thanks for your help

E065-0001 was fixed by Main Driver Board (PCB2) replacement.
E068-0001 was caused by loose connector from the High Voltage Unit to the Relay PCB (PCB5).
