• Code: C-2215
• Description: Hopper toner remaining sensor /2 (PS33) abnormality. When the toner is supplied for 8minutes, it is found that the toner remaining sensor /1 (PS32) does not turn ON and the PS33 turns OFF for the last 15seconds in succession.
• Causes: Hopper toner remaining sensor /1 (PS32) Hopper toner remaining sensor /2 (PS33) Printer control board (PRCB)
• Remedy: 1 Check the hopper section, and clean/repair it if any abnormality. - 2 Check the connector connection and the wiring between PRCB and the sensor, and repair it if any abnormality. - 3 Check the sensor, and repair/replace it if any abnormality. 4-M 4 Replace PS32. - 5 Replace PS33. - 6 Replace PRCB.

• 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 20seconds.
• 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. 4-M 4 Check the I/O drive of the motor and the coupling of the gear, and repair/replace it if any abnormality. 6-M 5 Replace PS34. - 6 Replace M28. - 7 Replace PRCB. - *After replacing the defective parts, be sure to set the DIPSW 3-1 to 0. If DIPSW3-1 is set to 0 before defective parts are fixed, it causes fire.

• 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. 6-M 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. 6-M 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. 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. 6-M 3 Replace M29 and PRCB at a time.

• Code: C-2226
• Description: Air pump motor (M29) rotation abnormality. 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. 6-M 4 Replace M29. - 5 Replace PRCB.
