• Code: C1030
• Description: PF lift motor 1 error (optional paper feeder)
  After cassette 3 is inserted, PF lift switch 1 does not turn on within 12 s. This error is detected two times successively. During driving the motor, the lift overcurrent protective monitor signal is detected for 500 ms or more two times successively. However, the first 1 s after PF lift motor 1 is turned on is excluded from detection.
• Causes: Poor contact in the connector terminals. Broken gears or couplings of PF lift motor 1. Defective PF lift motor 1. Defective PF lift switch 1.
• Remedy: Poor contact in the connector terminals. Check the connection of connector YC27 on the engine PWB and the connector on the PF main PWB, and the continuity across the connector terminals. Repair or replace if necessary.
  Broken gears or couplings of PF lift motor 1. Replace PF lift motor 1.
  Defective PF lift motor 1. Check for continuity across the coil. If none, replace PF lift motor 1.
  Defective PF lift switch 1. Check if YC1-7 on the PF main PWB goes low when PF lift switch 1 is turned off. If not, replace PF lift switch 1.

• Code: C1040
• Description: PF lift motor 2 error (optional paper feeder)
