Troubleshooting. When SC491-01 Is Displayed
Summary
If SC491-01 (Primary/secondary transfer: Output error) appears, it is mainly due to problems with the image transfer belt unit, transfer roller, high voltage power supply (HVP), or terminals of the development roller. This section explains how to examine the ITB unit, transfer roller unit, and HVP.
Examining Components
Examining the HVP
Check for a short circuit in the machine [A]. If it is conducting, the HVP is faulty. (Red circle: power terminal, Blue circle: body)
Examining the ITB Unit
Check for a short circuit in the ITB. If it is conducting, the ITB Unit is faulty. (Red circle: power terminal, Blue circle: ITB)
Examining the Transfer Roller Unit
Check for a short circuit in the Transfer Roller. If it is not conducting, check if the transfer roller and electrode plate are in contact.
