Fusing roller separation failure
• With the fusing roller being retracted, the pulse of the encoder sensor does not change even after the specified period of time has passed after the fusing pressure retraction motor started rotating. • With the fusing roller being pressed, the encoder pulse sensor does not change even after the specified period of time has passed after the fusing pressure retraction motor started rotating. • With the pressure roller being pressed, the pressure home sensor did not turn ON (pressed) even after the fusing retraction position sensor counted up the specified number of pulse after the fusing pressure retraction motor started rotating.
