• Code: C3101
• Description: Fusing roller separation failure
  • With the fusing roller being retracted, the pulse of the fusing roller retraction sensor does not change even after the specified period of time has passed after the fusing retraction motor started rotating. • With the fusing roller being pressed, the pulse of the roller retraction sensor does not change even after the specified period of time has passed after the fusing retraction motor started rotating. • During a pressure operation of the fusing roller, the fusing roller is not at the pressed position even after the roller retraction sensor counts the specified number of pulses after the fusing retraction motor starts rotating.
• Remedy: 1 Check the M12 connector for proper connection and correct as necessary. 2 PS38 I/O check, sensor check. 3 M12 operation check. 4 Change M12. 5 Change fusing unit. 6 Change PRCB.
