E000

The main thermistor reading does not reach 40oC 14 sec after the fixing heater goes ON (fixing low temperature error)

E001

The main thermistor reading reaches 220°C or higher (fixing high temperature error)

E002

A start-up fault is detected under any of the following conditions of the main thermistor (start-up detection fault):

after exceeding 40°C, it fails to reach 60°C within 10 sec.

after exceeding 60°C, it fails to reach 80°C within 10 sec.

. . .

after exceeding 180°C, it fails to reach 195°C within 10 sec.

E003

After the end of the WAIT period, the main thermistor reading is 100°C or lower. In standby, the sub thermistor reading is 50°C or lower. (low temperature error in fixing temperature control)

E004

At time of initialization, the ZEROXI* signal of the power supply is not detected.

During temperature control, the ZEROXI* signal does not arrive for 3 sec continuously.

A short circuit is detected in the triac (ASIC; fixing temperature control drive circuit error).

Possible cause: Fixing assembly is faulty. (The main thermistor has an open circuit. The sub thermistor has an open circuit. The fixing heater has an open circuit. The power supply PCB is faulty. The DC controller PCB is faulty.)

Note: If E000 through E004 is indicated, the RAM on the image processor will retain the error memory of the fixing assembly after the power switch has been turned off an then on. Execute the following in service mode, and turn off and then on the power switch to clear the memory:

#7 PRINTER - #4 PRINTER RESET - YES=(*)

E010

A specific revolution is not detected from the main motor rotation detection signal (MLOK*), causing the signal to go '1' (main motor fault)

Possible cause: The main motor (M101) is faulty. The controller PCB is faulty.

E100

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.

Possible cause: 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.

E719

The communication between the card reader and the image processor PCB is disrupted.

Possible cause: The wiring is faulty (short circuit, open circuit). The card reader is faulty. The image processor PCB is faulty.

Note: If E719 is indicated, the fault in communication is retained by the RAM on the image processor even when the power switch has been turned off and then on; be sure to execute #12 CLEAR - CARD in service mode before making corrections.

E805

After the heat discharge fan drive signal is generated, the fan lock detection signal does not arrive for a specific period of time.

Possible cause: The fan wiring is faulty (short circuit, open circuit). The heat discharge fan (FM101) is fautly. The DC controller PCB is faulty.

Finisher Error Codes

E500

An error has occurred in the communication between the machine and the finisher twice continuously.

Possible cause: The harness to the finisher is faulty (disconnected connector, open circuit). The finisher controller PCB or the DC controller PCB is faulty.

E514

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).

Possible cause: 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.

E530

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.

Possible cause: 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.

E531

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.

Possible cause: 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.

E537

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.

Possible cause: 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.

E551

The delivery fan rotation signal (FNALCOK) does not arrive within 1 sec when the heat discharge fan drive signal (FANON) is sent.

Possible cause: The heat discharge fan (FM1) is faulty. The heat discharge fan relay harness is faulty. The heat discharge fan is subjected to an abnormal load. The finisher controller PCB is faulty.

E577

The return roller does not reach home position when the delivery motor (M1) is driven for a specific time. (If the same condition is detected while alignment takes place in the direction of feed, a jam will be identified)

The delivery motor relay harness is faulty. The return roller is faulty. The finisher controller PCB is faulty.

E580

The stack tray upper limit sensor (S1) goes ON while the stack tray up/down motor (M5) is in operation.

The clock signal of the stack tray up/down clock sensor (S9) is not detected 15 times or more within 0.8 sec while the stack tray up/down motor (M5) is in operation.

It does not reach the stack tray paper height sensor (S10) 2 sec after the stack tray up/down motor (M5) rotates for ascent.

It does not leave the stack tray power height sensor (S10) 2 sec after the stack tray up/down motor (M5) starts to rotate for descent.

Possible cause: The stack tray up/down motor (M5) is faulty. The stack tray paper height sensor (S10) is faulty. The sensor connector is disconnected or has an open circuit.
