• Code: U6-22
• Description: LCC 24V power abnormality. DC 24V is not supplied to the LCC
• Causes: Connection trouble or disconnection of the connector and the harness. LCC control PWB trouble. Power source unit trouble.
• Remedy: Check the connector and the harness in the power source line. Check that the power unit and the LCC control PWB is of 24V.

• Code: U6-23
• Description: A3LCC tray lock detection trouble (Reverse winding). The LCC tray wire is wound in reverse
• Causes: Reverse winding SW-ON. The wire is wound in reverse. Reverse winding detection SW trouble. Connection trouble of the connector and the harness. LCC control PWB trouble.
• Remedy: Check the wire. Replace the reverse winding SW and the LCC control PWB. Check connection of the connector and the harness.

• Code: U6-24
• Description: A3LCC tray lock detection trouble. The LCC tray lock function does not operate normally
• Causes: Tray lock mechanism trouble. Tray lock sensor trouble. Connection trouble of the connector and the harness. LCC control PWB trouble.
• Remedy: Check the tray lock mechanism. Replace the tray lock sensor and the LCC control PWB. Check connection of the connector and the harness.

• Code: U6-28
• Description: LCT1 paper feed position abnormality. When the lift-up operation is started, the upper limit sensor is turned OFF before the pick-up SOL is turned ON. (Normally the upper limit sensor is turned OFF only after turning ON the pick-up SOL.)
• Causes: Sensor abnormality, connector and harness connection trouble, PWB trouble. The pick-up roller is kept in the lower position mechanically.
• Remedy: Use Sim. 4-2 and Sim. 4-3 to check the operation of the upper limit sensor and the lift-up operation, and check the wiring.

• Code: U6-29
• Description: LCT1 lift-up trouble. When lifting up, the upper limit is not detected within the specified time (A4 LCC: 10 sec, A3 LCC: 8 sec)
• Causes: Upper limit sensor abnormality, tray lift-up motor lock, connector/harness connection trouble, PWB trouble
• Remedy: Use Sim. 4-2 and Sim. 4-3 to check the operation of the upper limit sensor and the lift-up operation, and check the wiring. After making the countermeasure for the trouble section, use Sim. 15 to cancel the trouble.

• Code: U6-33
• Description: LCT2 lift-down trouble. The lower limit position (full state) of the LCT2 tray is not detected within the specified time (A4: 10sec, A3: 8sec) from starting lowering.
• Causes: Remaining quantity sensor abnormality, LCT2 tray lift-up motor lock, connector/harness connection trouble, PWB trouble.
• Remedy: Use Sim. 4-2 and Sim. 4-3 to check the operation of the remaining quantity sensor and the LCT2 tray lift-up motor, and check the wiring.

• Code: U6-38
• Description: LCT2 paper feed position abnormality. When the lift-up operation is started, the upper limit sensor is turned OFF before the pick-up SOL is turned ON. (Normally the upper limit sensor is turned OFF only after turning ON the pick-up SOL.)
• Causes: Sensor abnormality, connector and harness connection trouble, PWB trouble. The pick-up roller is kept in the lower position mechanically.
• Remedy: Use Sim. 4-2 and Sim. 4-3 to check the operation of the upper limit sensor and the lift-up operation, and check the wiring.

• Code: U6-39
• Description: LCT2 lift-up trouble. When lifting up, the upper limit is not detected within the specified time (A4 LCC: 10 sec, A3 LCC: 8 sec)
• Causes: Upper limit sensor abnormality, tray lift-up motor lock, connector/harness connection trouble, PWB trouble.
• Remedy: Use Sim. 4-2 and Sim. 4-3 to check the operation of the upper limit sensor and the lift-up operation, and check the wiring. After making the countermeasure for the trouble section, use Sim. 15 to cancel the trouble.
