• Code: C0996
• Description: 3rd Drawer lock release failure
• Remedy: 1 3rd Drawer Lock Solenoid operation: the voltage across PJ6A-2 on the Master Board and GND is DC24V (solenoid deenergized) and DC0V (solenoid energized, instantaneous) when the Paper Descent key is pressed and the Main Tray completes its descent motion. YES Change solenoid. NO Change Master Board.

• Code: C0998
• Description: Shifter transfer failure
• Remedy: 1 Shifter Return Position Sensor operation: the voltage across PJ3A-5 on the Master Board and GND is DC5V (sensor unblocked) and DC0V (sensor blocked). YES Change Master Board. NO Change sensor, Cabinet Transport Board, and flat cable.

• Code: C0999
• Description: Shifter return failure
• Remedy: 1 Shifter Return Position Sensor operation: the voltage across PJ3A-5 on the Master Board and GND is DC5V (sensor unblocked) and DC0V (sensor blocked). YES Change Master Board. NO Change sensor, Cabinet Transport Board, and flat cable.

• Code: C099A
• Description: Shifter return failure
• Remedy: 1 Shifter Home Position Sensor operation: the voltage across PJ3A-4 on the Master Board and GND is DC5V (sensor unblocked) and DC0V (sensor blocked). YES Change Master Board. NO Change sensor, Cabinet Transport Board, and flat cable.

• Code: C099b
• Description: Shifter transfer failure
• Remedy: 1 Shifter Home Position Sensor operation: the voltage across PJ3A-4 on the Master Board and GND is DC5V (sensor unblocked) and DC0V (sensor blocked). YES Change Master Board. NO Change sensor, Cabinet Transport Board, and flat cable.

• Code: C099c
• Description: Shift Motor’s failure to turn
• Remedy: 1 Shift Motor turns when the 3rd Drawer is slid into the copier with a paper stack loaded in the Shift Tray (the paper stack to be shifted to the Main Tray). NO Correct drive coupling. 2 Shift Motor operation: the voltage across PJ10A-4 (rightward motion)/PJ10A-3 (leftward motion) on the Master Board and GND is DC0V (motor deenergized) and DC24V (motor energized) when step 1 is performed. YES Change Shift Motor, Cabinet Transport Board, and flat cable. NO Change Master Board. 3 Shift Motor Pulse Sensor operation: the voltage across PJ9A-12 on the Master Board and GND varies in the range between DC0V and DC5V while the Shift Motor is energized. YES Change Master Board. NO Change pulse disk and gear. Change sensor.

• Code: C099E
• Description: Shift Gate position detecting failure
• Remedy: 1 Shift Gate Position Detecting Sensor operation: the voltage across PJ3A-7 on the Master Board and GND is DC5V (sensor unblocked) and DC0V (sensor blocked). YES Change Master Board. NO Change sensor, Cabinet Transport Board, and flat cable.

• Code: C099F
• Description: Shift Gate position detecting failure
• Remedy: 1 Shift Gate Position Detecting Sensor operation: the voltage across PJ3A-7 on the Master Board and GND is DC5V (sensor unblocked) and DC0V (sensor blocked). YES Change Master Board. NO Change sensor, Cabinet Transport Board, and flat cable.
