Description: Paper feeder lift motor 1 error (optional paper feeder) When optional cassette 3 is inserted, paper feeder lift switch 1 does not turn on within 12 s of paper feeder lift motor 1 turning on. The lift overcurrent protective monitor signal is detected above 500 ms during driving the motor. However, the first 1 s after paper feeder lift motor 1 is turned on is excluded from detection.
Causes: Poor contact in the connector terminals. Broken gears or couplings of paper feeder lift motor 1. Defective paper feeder lift motor 1. Defective paper feeder lift switch 1.
Remedy: Poor contact in the connector terminals. Check the connection of connector on the engine PWB and the connector on the paper feeder main PWB, and the continuity across the connector terminals. Repair or replace if necessary. Broken gears or couplings of paper feeder lift motor 1. Replace paper feeder lift motor 1. Defective paper feeder lift motor 1. Check for continuity across the coil. If none, replace paper feeder lift motor 1. Defective paper feeder lift switch 1. Check if YC1-5 on the paper feeder main PWB goes low when paper feeder lift switch 1 is turned off. If not, replace paper feeder lift switch 1.
Code: C1040
Description: Paper feeder lift motor 2 error (optional paper feeder) When optional cassette 4 is inserted, paper feeder lift switch 2 does not turn on within 12 s of paper feeder lift motor 2 turning on. The lift overcurrent protective monitor signal is detected above 500 ms during driving the motor. However, the first 1 s after paper feeder lift motor 2 is turned on is excluded from detection.
Causes: Poor contact in the connector terminals. Broken gears or couplings of paper feeder lift motor 2. Defective paper feeder lift motor 2. Defective paper feeder lift switch 2.
Remedy: Poor contact in the connector terminals. Check the connection of connector on the engine PWB and the connector on the paper feeder main PWB, and the continuity across the connector terminals. Repair or replace if necessary. Broken gears or couplings of paper feeder lift motor 2. Replace paper feeder lift motor 2. Defective paper feeder lift motor 2. Check for continuity across the coil. If none, replace paper feeder lift motor 2. Defective paper feeder lift switch 2. Check if YC1-7 on the paper feeder main PWB goes low when paper feeder lift switch 2 is turned off. If not, replace paper feeder lift switch 2.
Code: C1100
