HV Power Supply 7 Can you fix the problem if you replace the HV Power Supply? Yes OK
Code: E-0034
Description: Bias Output Error
Causes: Bias Output Detection Signal (BIAS_LD) continues to be “L” for 1 second or longer when a specified bias is supplied to the corresponding Developer Unit components.
Remedy: Wires 1 Are wires among Developer Unit, HV Power Supply PCB and PW11720 PCB connected properly? No Connect them properly. Developer Unit 2 Is the toner spill out from the Developer Unit? (Or is there any similar problem?) Yes Clean each Corona Wire, Grid Plate and housing. Is the high voltage of Regulation Roller leaking? (The resistance between the central part of Regulation Roller and the Ground is 5 mega ohm or smaller if leaking.) Yes Replace the Regulation Roller. HV Power Supply 3 Can you fix the problem if you replace the HV Power Supply? Yes OK
