• Code: E535-0004
• Description: There is a fault in the swing mechanism. Finisher-N1/Saddle Finisher-N2
  The swing motor (M7) or the swing motor clock sensor (PI20) is faulty. There is no clock pulse for 0.2 sec while swinging operation is under way.

• Code: E537
• Description: There is a fault in front alignment. Finisher-M1
  The front alignment motor (M3) or the front aligning plate home position sensor (S6) is faulty. An excess load is imposed on the front aligning plate. The aligning plate fails to reach the aligning plate home position sensor when the rear alignment motor has been driven for a specific period of time, or fails to leave the aligning plate home position sensor.

• Code: E540-0001
• Description: There is a fault in the ascent/descent of the tray. Finisher-N1/Saddle Finisher-N2
  The tray ascent/descent motor (M5), the tray ascent/descent motor clock sensor (PI9/PI19), or tray home position sensor (PIE) is faulty. The ascent/descent operation does not end within 15 sec after the tray assent/descent motor has been driven; or, the tray home position is not detected when it has been driven for 15 sec.

• Code: E540-0002
• Description: There is a fault in the ascent/descent of the tray. Finisher-N1/Saddle Finisher-N2
  The tray upper limit detecting switch (MS5) is faulty. The tray upper limit detecting switch is ON during tray ascent/descent operation.

• Code: E540-0003
• Description: There is a fault in the ascent/descent of the tray. Finisher-N1/Saddle Finisher-N2
  The tray ascent/descent motor (M5) or the tray ascent /descent motor clock sensor 1/2 (PI9/ PI19) is faulty. There is no clock pulse for 0.2 sec or more from the clock sensor when the tray ascent/ descent motor has been driven.

• Code: E577
• Description: There is a fault in stack processing (counterclockwise direction). Finisher-M1
  The stack processing motor (M2) or the return controller home position sensor (S3) is faulty. The connector is disconnected. The stack delivery lever or the return roller is faulty. The return roller fails to reach the return roller home position sensor when the stack processing motor has been driven for a required period of time.

• Code: E580
• Description: There is a fault in ascent/descent of the stack tray. Finisher-M1
  The stack tray ascent/descent motor (M5), stack tray paper height sensor (S10), or the stack tray ascent/descent motor clock sensor (S9) is faulty. The connector is disconnected. An excess load is imposed on the stack tray ascent/descent motor. The stack tray upper limit sensor goes ON while the stack tray ascent/descent motor is in operation, or the clock pulse of the stack tray direction motor clock sensor is not detected 15 times or more within 0.8 sec. The stack tray does not reach the stack tray height sensor within 4 sec after the stack tray ascent/descent motor has started ascent operation.

• Code: E584-0001
• Description: There is a fault in feed operation (No. 2). Finisher-N1/Saddle Finisher-N2
  The No. 2 feed motor (M8) or the shutter open sensor (PI5) is faulty. The shutter open sensor does not go ON when the No. 2 feed motor has been rotated in reverse for 1 sec or more.
