Code: C-2217
Description: Leakage at the mixing section is detected. When the toner pump motor (M28) is operating, the cup section toner remaining sensor (PS34) detects the toner being provided in succession for seconds.
Causes: • Cup section toner remaining sensor (PS34) • Toner pump motor (M28) • Printer control board (PRCB)
Remedy: 1. Check the toner mixing section, and clean/repair it if any abnormality. 2. Check the connector connection and the wiring between PRCB and motor/sensor, and repair it if any abnormality. 3. Check the sensor, and repair/replace it if any abnormality.(Wiring diagram: Main body (3/4): 7-D, 8-P) 4. Check the I/O drive of the motor and the coupling of the gear, and repair/replace it if any abnormality. (Wiring diagram:Main body (3/4): 3-P) 5. Replace PS34. 6. Replace M28. 7. Replace PRCB.

Code: C-2220
Description: Toner pump motor (M28) rotation abnormality + 24V power abnormality. While M28 is rotating, an error detection signal (abnormal rotation/24V cut off) is detected for more than 1second.
Causes: • DC power supply /2 (DCPS/2) • Printer control board (PRCB)
Remedy: 1. Check the connector connection and the wiring between PRCB and DCPS /2, and repair it if any abnormality. 2. Check the connector connection and the wiring between PRCB and the motor, and repair it if any abnormality. 3. Replace DCPS /2. 4. Replace PRCB.

Code: C-2221
Description: Toner pump motor (M28) power abnormality. While M28 is rotating, an error detection signal (abnormal rotation) is detected for more than 1second. At this time, an abnormality signal (blowout of ICP) is detected, but no abnormality signal (24V cut off) is detected.
Causes: • Toner pump motor (M28) • Printer control board (PRCB)
Remedy: 1. Check the connector connection and the wiring between PRCB and the motor, and repair it if any abnormality. 2. Check the I/O drive of the motor and the coupling of the gear, and repair/replace it if any abnormality. (Wiring diagram:Main body (3/4): 3-P) 3. Replace M28 and PRCB at a time.

Code: C-2222
Description: Toner pump motor (M28) rotation abnormality. While M28 is rotating, an error detection signal (abnormal rotation) is detected for more than 1second. At this time, an error detection signal (blowout of ICP/24V cut off) is not detected.
Causes: • Toner pump motor (M28) • Printer control board (PRCB)
Remedy: 1. Check the toner pump section, and clean/repair it if any abnormality. 2. Check the connector connection and the wiring between PRCB and the motor, and repair it if any abnormality. 3. Check the I/O drive of the motor and the coupling of the gear, and repair/replace it if any abnormality. (Wiring diagram:Main body (3/4): 3-P) 4. Replace M28. 5. Replace PRCB.

Code: C-2224
Description: Air pump motor (M29) rotation abnormality + 24V power abnormality. While M29 is rotating, an error detection signal (abnormal rotation) is detected for more than 1second. At this time, an error signal (24V cut off) is detected.
Causes: • DC power supply /2 (DCPS/2) • Printer control board (PRCB)
Remedy: 1. Check the connector connection and the wiring between PRCB and DCPS /2, and repair it if any abnormality. 2. Check the connector connection and the wiring between PRCB and the motor, and repair it if any abnormality. 3. Replace DCPS /2. 4. Replace PRCB.

Code: C-2225
Description: Air pump motor (M29) power abnormality. While M29 is rotating, an error detection signal (abnormal rotation) is detected for more than 1second. At this time, an abnormality signal (blowout of ICP) is detected, but no abnormality signal (24V cut off) is detected.
Causes: • Air pump motor (M29) • Printer control board (PRCB)
Remedy: 1. Check the connector connection and the wiring between PRCB and the motor, and repair it if any abnormality. 2. Check the I/O drive of the motor and the coupling of the gear, and repair/replace it if any abnormality. (Wiring diagram:Main body (3/4): 4-P) 3. Replace M29 and PRCB at a time.

Code: C-2226
Description: Air pump motor (M29) rotation abnormality. While M29 is rotating, an error detection signal (abnormal rotation) is detected for more than 1second. At this time, an error detection signal (blowout of a fuse/24V cut off) is not detected.
Causes: • Air pump motor (M29) • Printer control board (PRCB)
Remedy: 1. Check the air pump section, and clean/repair it if any abnormality. 2. Check the connector connection and the wiring between PRCB and the motor, and repair it if any abnormality. 3. Check the I/O drive of the motor and the coupling of the gear, and repair/replace it if any abnormality. (Wiring diagram:Main body (3/4): 4-P) 4. Replace M29. 5. Replace PRCB.

Code: C-2227
Description: Developing screw motor (M21) rotation abnormality. The M21EM error detection signal is detected twice in succession within a specified period of time after M21 was turned ON. However, an error detection signal (blowout of ICP) is not detected.
Causes: • Developing screw motor (M21) • Printer control board (PRCB)
Remedy: 1. Check the developing screw section, and clean/repair it if any abnormality. 2. Check the connector connection and the wiring between PRCB and the motor, and repair it if any abnormality. 3. Check the I/O drive of the motor and the coupling of the gear, and repair/replace it if any abnormality. (Wiring diagram:Main body (3/4): 19-P) 4. Replace M21. 5. Replace PRCB.
