Description: Error in take-up of Sealing Member (Y). The patch output value (SigR) failed to be 900 or less during initialization of the Developing Unit (Y).
Remedy: [Related parts] • Harnesses from the Registration Patch Sensor Unit to the DC Controller PCB 1. Registration Patch Sensor Unit to Relay Connector (16P) (Unit of replacement: REGISTRATION SENSOR ASSEMBLY) 2. Relay Connector (16P) to DC Controller PCB (UN04/J120) (Unit of replacement: NEW OLD SENSING HOLDER ASS'Y) • Harness between the Secondary Transfer High Voltage PCB (UN03/J501 and J502) and the DC Controller PCB (UN04/J114 and J112) (Unit of replacement: CABLE, 2ND TRNSFR. H.V. PCB) • Registration Patch Sensor Unit (Unit of replacement: REGISTRATION SENSOR ASSEMBLY) • Developing Unit (Y) (Unit of replacement: DEVELOPING ASSEMBLY, Y) • Secondary Transfer High Voltage PCB (UN03) (Unit of replacement: 2ND TRANSFER H.V. PCB ASSEMBLY) • DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY) [Remedy] Check/replace the related harness/cable, connector and parts. [Reference] Before replacing the DC Controller PCB, back up the service mode data (approx. 2 min) and restore the backup data after the replacement so the data may be able to be protected. • Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP • Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES
