Paper feed or ejection is abnormal. Paper end is determined even though media remains.
Suspected cause
PF Scale, PF Encoder failure
PF Belt tension abnormality
Sub PF Scale, Sub PF Driven Roller Encoder abnormality
Sub PF Belt tension is inappropriate
Suction power of Suction Fan setting failure
Suction Fan failure
PF Driven Roller Motor failure
Sub PF Driven Roller Motor failure
Flange clogged with paper dust
Flange failure (in the slack take-up operation the flange may be insufficient and result in paper folding, but the printer determines that the paper is being fed correctly).
Parts/Components to be checked
PF Scale
PF Encoder
PF Belt
PF Driven Roller Motor
Sub PF Scale
Sub PF Encoder
Sub PF Belt
