Description: Unstable rotation of the Fixing Motor (M2)
Causes: Detection is executed every 100 msec after the start of motor rotation; however, the drive detection signal is absent for 2 sec.
Remedy: [Related parts] - Harness connecting from the DC Controller PCB (UN2/J331) to the Fixing Motor (M2/J730) - Fixing Motor (M2) - DC Controller PCB (UN2) [Remedy] 1.Check/replace the related harness/cable, connector and parts. 2.Replace the DC Controller PCB. [Reference] Before replacing the DC Controller PCB, back up the service mode data 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
