The status counter is dispalyed as follows: [C41]: "1" or "2" [C42]: "6" [C43]: "4" [C44]: "5" [C46]: "7" [C47]: "8" [C48]: "9" (4) Turn OFF the power and then back it ON again, and make sure that the copier gets ready normally.

Error code:	C49
Description:	Abnormal IH circuit or coil
Causes:	• If the actuator of the Master disposal unit set switch is not depressed.
Remedy:	1. Check the IH control board (1) Check if the conductor pattern on the board is short or open-circuited. (2) Replace the IH control board. 2. Check the IH coil (1) Check if the coil is broken or shorted. (2) Replace the IH coil. 3. Clear the status counter Change the values “13”, “15”, “16” or “19” of the status counter (08-400) to “0”. * The status counter value is as follows in the following cases. Change them to "0" respectively. • The error occurred before the temperature of the fuser roller reaches 40°C: "13" • The error occurred before the temperature of the fuser roller reaches 150°C: "16" • The error occurred before the machine has become ready: "15" • The error occurred when the machine is in the ready state: "19" [C47], [C48] and [C49] can be cleared by turning OFF and ON the main switch as long as the problem was solved, and the status counter does not have to be changed to "0". The value of the status counter remains until the next service call overwrites the value.

Error code:	C55
Description:	RADF I/F error
Remedy:	Is the harness between the ADF board and SLG board open-circuited? Replace the harness. Is the ADF board short- or open-circuited? 1. Replace the ADF board. 2. Perform the EEPROM initialization of RADF, sensor automatical adjustment and tray width sensor adjustment. Replace the SLG board.

Error code:	C57
Description:	Communications error between LGC-CPU and IPC board
Remedy:	(1) Check if any conductor pattern on the LGC board, mainly around IC23, IC72, IC74 and J125, is short- or open-circuited. (2) Check if the conductor pattern on the IPC board is short- or open-circuited. (3) Replace the IPC board. (4) Replace the LGC board.

Error code:	C58
Description:	Communication error between IPC board and finisher
Causes:	• If the actuator of the Master making unit set switch is not depressed.
Remedy:	Is a specified finisher used? Replace to the specified finisher. Is the harness between the IPC board and finisher control board open-circuited? Replace the harness. Is the conductor pattern on the IPC board is short- or open-circuited? Replace the IPC board. Replace the finisher control board.

Error code:	C71
Description:	ADF feed motor is abnormal
Remedy:	(1) Check if the load on the motor shaft is normal. (2) Check the mechanical load and adjust the drive system. Remove foreign objects. (3) Check if the power is supplied to connector CN11 of the motor. (4) Check the circuits and connectors on the ADF control board, mainly IC6, Q19, Q20, Q21, Q22 and CN11, for short- and open-circuits. (5) Replace the ADF control board. (6) Replace the ADF feed motor.

Error code:	C73
Description:	EEPROM initializing error
Remedy:	1. Check if any conductor pattern on the RADF PC board is open- or short-circuited mainly around IC7. 2. Replace the RADF PC board. 3. Initialize the RADF`s EEPROM and perform the sensor automatic adjustment.

Error code:	C74
Description:	Paper exit sensor automatic adjustment error
Remedy:	1. Check if any foreign matter is present between the exit sensor and the reflecting mirror, and if the reflecting mirror is stained. 2. Check if the harness between the exit sensor and the RADF PC board is open-circuited. 3. Check if any conductor pattern on the RADF PC board is open- or short-circuited mainly around IC1, IC14 and CN8. 4. Replace the exit sensor. 5. Replace the RADF PC board. 6. Initialize the RADF`s EEPROM and perform the sensor automatic adjustment.

Error code:	C81
Description:	Transport motor trouble
Remedy:	[Procedure 1] Is the No.2 transport motor (M8) operating in reverse at the fixed timing? No Replace the transport motor or finisher controller board. Yes Is the shutter correctly coupled to the shutter upper/lower bars? No Correctly couple. Yes Try turning transport roller 2 in reverse by hand. Do the shutter upper/lower bars move up and down? No Correct the mechanism from the shutter upper/lower bars up to the gears of transport roller 2. Yes Is the shutter close detection switch (MS4) normal? No Replace the switch. Yes Replace the finisher controller board. [Procedure 2] Is the No.2 transport motor (M8) operating in reverse at the fixed timing? No Replace the transport motor or finisher controller board. Yes Is the shutter correctly coupled to the shutter upper/lower bars? No Correctly couple. Yes Try turning transport roller 2 in reverse by hand. Do the shutter upper/lower bars move up and down? No Correct the mechanism from the shutter upper/lower bars up to the gears of transport roller 2. Yes Is the shutter open sensor (PI5) normal? No Replace the sensor. Yes Replace the finisher controller board.

Error code:	C82
Description:	Communications error between scanner and ADF
