Description: When the scanner motor is started up, the BD input signal does not arrive within a specific period of time.
When the scanner motor is started up, the motor rotation is too fast, and fails to reach a specific revolution within 20 sec at time of deceleration.
While the scanner motor is rotating at a specific speed, the BD input signal cycle is not within a specific range (±2%) for an equivalent of 10 mm (print distance).
While the scanner motor is rotating at a specific speed, the BD input signal cycle is not as indicated (±2%).
During the WMUPR period after the power switch has been turned on or the front cover/left cover has been opened/closed, the drum unit is absent.
Causes: The wiring is faulty (short circuit, open circuit). The laser scanner unit is faulty. The DC controller PCB is faulty. The drum unit is not installed.
Remedy: 1) Drum unit Is the drum unit installed in host machine? NO : Install the drum unit. 2) Connection Is the connection of the connector (J908) on the BD detection PCB, connector (J907) of the laser unit, and connector (J102) on the DC controller PCB normal? NO : Correct the connection. 3) Laser/scanner unit, DC controller PCB Try replacing the laser/scanner unit. Is the fault corrected? YES : End. NO : Replace the DC controller PCB.
Code: E500
Description: An error has occurred in the communication between the machine and the finisher twice continuously.
Causes: The harness to the finisher is faulty (disconnected connector, open circuit). The finisher controller PCB or the DC controller PCB is faulty.
Remedy: 1) Power switch Try turning off and then on the power switch. Is the fault corrected? YES : End. 2) Wiring Is the wiring from the finisher controller PCB to the DC controller PCB normal? NO : Corrected the wiring. 3) Finisher controller PCB, DC controller PCB Try replacing the finisher controller PCB. Is the fault corrected? YES : End. NO : Replace the DC controller PCB.
Code: E514
Description: The stack delivery belt does not reach home position when the stack handling motor (M2) is driven for a specific time (CW; if the same condition occurs during stack delivery, a jam will be identified).
Causes: The stack handling motor (M2) is faulty. The stack delivery home position sensor (S8) is faulty. The connector is disconnected or has an operation circuit. The stack handling motor relay harness is faulty. The stack delivery belt is faulty. The finisher controller PCB is faulty.
Remedy: 1) Stack handling motor drive belt Is the tension of the drive belt appropriate? NO : Loosen the screw on the tension to correct the tension. 2) Wiring Is the wiring between the finisher controller PCB and the harness handling motor (M2) normal? NO : Correct the wiring. 3) Sensor flag Are the sensor flag spring and the flag normal? NO : Correct the spring or the flag. 4) Stack delivery lever home position sensor (S8) Check the stack delivery lever home position sensor (S8). Is the sensor normal? NO : Replace the sensor. 5) Stack handling motor (M2), Finisher controller PCB Try replacing the stack handling motor (M2). Is the fault corrected? YES : End. NO : Replace the finisher controller PCB.
Code: E530
Description: The rear aligning plate does not reach home position when the rear alignment motor (M4) has been driven for a specific time.
The rear aligning plate does not reach home position when the rear alignment motor (M4) has been driven for a specific time.
Causes: The rear alignment motor (M4) is faulty. The rear aligning plate home position sensor (S7) is faulty. The sensor connector is disconnected or has an open circuit. The rear alignment motor relay harness is faulty. The rear aligning plate is subjected to an abnormal load. The finisher controller PCB is faulty.
Remedy: 1) Rear aligning plate home position sensor (S7) Check the rear aligning plate home position sensor (S7). Is the sensor normal? NO : Replace the sensor. 2) Wiring List the wiring between the finisher controller PCB and the rear alignment motor (M4). NO : Correct the wiring. 3) Rear aligning plate Is the rack riding cover the collar of the roll? YES : Correct it. 4) Rear alignment motor (M4), Finisher controller PCB Try replacing the rear alignment motor (M4). Is the fault corrected? YES : End. NO : Replace the finisher controller PCB.
Code: E531
Description: The stapler does not leave the stapling home position sensor (S13) within 0.5 sec after the stapler motor (M6) is rotated CW.
The stapler does to return to the home position sensor (S13) within 0.5 sec after the stapler motor (M6) is driven CW and, in addition, it does not return to the sensor within 0.5 sec after the motor is driven CCW thereafter.
Causes: The stapler motor (M6) is faulty. The stapler home position sensor (SW1) is faulty. The stapler harness is faulty. The finisher controller PCB is faulty.
Remedy: 1) Wiring It the wiring between the stapler unit and the finisher controller PCB normal? NO : Correct the wiring. 2) Stapler unit, Finisher controller PCB Try replacing the stapler unit. Is the fault corrected? YES : End. NO : Replace the finisher controller PCB.
Code: E537
Description: The front aligning plate does not reach home position when the front aligning motor (M3) is driven for a specific time.
The front aligning plate does not leave home position when the front alignment motor (M3) is driven for a specific time.
Causes: The front alignment motor (M3) is faulty. The front aligning plate home position sensor (S6) is faulty. The sensor connector is disconnected or has an open circuit. The front alignment motor relay harness if faulty. The front aligning plate is subjected to an abnormal load. The finisher controller PCB is faulty.
Remedy: 1) Front aligning plate home position sensor (S6) Check the front aligning plate home position sensor (S6). Is the sensor normal? NO : Replace the sensor. 2) wiring Is the wiring between the finisher controller PCB and the front alignment motor (M3) normal? NO : Correct the wiring. 3) Front aligning plate Is the rack riding over the collar of the roll? YES : Correct it. 4) Front alignment motor (M3), Finisher controller PCB Try replacing the front alignment motor (M3). Is the problem corrected? YES : End. NO : Replace the finisher controller PCB.
