• Code: C-0022
• Description: Initial communication check between the ADU drive board (ADUDB)/ printer control board (PRCB). ADU drive serial input abnormality 3. Within a specified period of time after the ACK at the time of the main power switch (SW1) being turned ON, a serial data from ID = 9 of the ADUDB is not received.
• Causes: Confirmation of the wiring harness and the connector ADU drive board (ADUDB) Printer control board (PRCB)

• Code: C-0101
• Description: An abnormal speed signal of the paper feed motor (M4) is checked. An error detection signal is detected twice in succession a specified period of time after M4 was turned ON (the first signal is ignored).
• Causes: Confirmation of the wiring harness and the connector Paper feed motor (M4) Printer control board (PRCB)

• Code: C-0102
• Description: An abnormal speed signal of the paper feed motor (M101) is checked. An error detection signal is detected twice in succession a specified period of time after M101 was turned ON (the first signal is ignored).
• Causes: Confirmation of the wiring harness and the connector Paper feed motor (M101) Printer control board (PRCB)

• Code: C-0104
• Description: The 24V power source for SD/CL in the printer control board (PRCB) is checked. At the start, an error detection signal (blowout of ICP for the solenoid/clutch) is detected, and an error detection signal (24V cut off) is also detected.
• Causes: Confirmation of the wiring harness and the connector Wiring harness earth fault Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-0105
• Description: The blowout of ICP for the SD/CL in the printer control board (PRCB) is checked. At the start, an error detection signal (blowout of ICP for the solenoid/clutch) is detected. However, an error detection signal (24V cut off) is not detected.
• Causes: Loose connection (on PRCB) Solenoid (SD5 to SD10, SD4, SD11) Clutch (CL3 to CL8, CL9, CL10) Wiring harness earth fault Printer control board (PRCB)

• Code: C-0210
• Description: The locking of the paper lift motor /1 (M19) is detected. An error detection signal of M19 is detected while M19 is ON.
• Causes: Tray 1 paper improperly loaded Tray 1 rear end restriction plate misaligned Confirmation of the wiring harness and the connector Paper lift motor /1 (M19) Upper limit sensor /1 (PS20) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-0211#
• Description: When the upper limit sensor /1 (PS20) is OFF, PS20 does not turn ON within a specified period of time after the paper lift motor / 1 (M19) turns ON for lifting operation. And at this time, an error detection signal (24V cut off) is detected.
• Causes: Tray 1 paper improperly loaded Tray 1 rear end restriction plate misaligned Confirmation of the wiring harness and the connector Paper lift motor /1 (M19) Upper limit sensor /1 (PS20) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-0212#
• Description: When the upper limit sensor /1 (PS20) is OFF, PS20 does not turn ON within a specified period of time after the paper lift motor / 1 (M19) turns ON for lifting operation. At this time, an error detection signal (blowout of ICP) is detected.
• Causes: Tray 1 paper improperly loaded Tray 1 rear end restriction plate misaligned Confirmation of the wiring harness and the connector Paper lift motor /1 (M19) Upper limit sensor /1 (PS20) Printer control board (PRCB) DC power supply /2 (DCPS2)
