home position detecting sensor is not sensed within a predetermined time.
Does the paper width motor rotate? YES Check paper width home position
NO detecting sensor output PSWSN(CN-2)
Changed: Duplex unit control PCB is defective.
Not changed: Check DC+5V on CN-1.
Detected: Check sensor.

Is DC+24V detected on CN653-7? NO Check DC+24V line.
YES
Paper width motor is defective.
Duplex unit control PCB is defective.
