• Code: C1120
• Description: Deck right lift position problem • Deck level switch 2 does not turn on within 30 s of paper deck motor 2 turning on.
• Causes: Defective deck level switch 2. Poor contact of deck level switch 2 connector terminals. Defective paper deck motor 2. Poor contact of paper deck motor 2 connector terminals. The deck right lift does not rise properly.
• Remedy: Check if CN5-4 on the desk main PCB goes low when desk level switch 2 is turned off. If not, replace desk level switch 2. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable. Check for continuity across the coil. If none, replace paper desk motor 2. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable. Check the gears and belts, and remedy if necessary.

• Remedy: Check if CN5-7 on the desk main PCB goes low when desk level switch 1 is turned off. If not, replace desk level switch 1. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable. Check for continuity across the coil. If none, replace paper desk motor 1. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable. Check the gears and belts, and remedy if necessary.

• Code: C2000
• Description: Drive motor problem • LOCK ALM signal remains high for 1 s, 1 s after the drive motor has turned on.
• Causes: Poor contact in the drive motor connector terminals. Defective drive motor rotation control circuit. Defective drive transmission system.
• Remedy: Reinsert the connector. Also check for continuity within the connector cable. If none, remedy or replace the cable. Replace the drive motor. Check if the rollers and gears rotate smoothly. If not, grease the bushings and gears. Check for broken gears and replace if any.

• Code: C2500
• Description: Paper feed motor problem • LOCK ALM signal remains high for 1 s, 1 s after the paper feed motor has turned on.
• Causes: Poor contact in the paper feed motor connector terminals. Defective paper feed motor rotation control circuit. Defective drive transmission system.
• Remedy: Reinsert the connector. Also check for continuity within the connector cable. If none, remedy or replace the cable. Replace the paper feed motor. Check if the rollers and gears rotate smoothly. If not, grease the bushings and gears. Check for broken gears and replace if any.

• Code: C2600
• Description: Deck conveying motor/desk drive motor problem • No pulse is input within 500 ms of the start-up. • No pulse is input within 100 ms of the previous pulse input.
• Causes: Defective deck conveying motor PCB/desk drive motor PCB. Deck conveying motor /desk drive motor does not rotate correctly (the motor is overloaded). Poor contact in the deck conveying motor/desk drive motor connector terminals.
• Remedy: Replace the deck conveying motor PCB/ desk drive motor PCB and check for correct operation. Check the gears and remedy if necessary. Reinsert the connector. Also check for continuity within the connector cable. If none, remedy or replace the cable.

• Code: C3100
• Description: Scanner carriage problem • The home position is not correct when the power is turned on or at the start of copying using the bypass table.
• Causes: Poor contact in the connector terminals. Defective scanner home position switch. Defective main PCB or scanner drive PCB. Defective scanner motor.
• Remedy: Check the connection of connector YC37 on the main PCB and the continuity across the connector terminals. Repair or replace if necessary. Replace the scanner home position switch. Replace the main PCB or scanner drive PCB and check for correct operation. Replace the scanner motor.

• Code: C3200
• Description: Exposure lamp problem • Non-lighting of the exposure lamp is detected at the beginning of copying.
