2. Main power supply PCB, DC controller PCB Try replacing the main power supply PCB. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.

E001-0002

The sub thermistor detects about 295C or higher

2. Main power supply PCB, DC controller PCB Try replacing the main power supply PCB. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.

E002-0000

The temperature of the fixing film is as follows: has exceeded 100C, but does not reach 115C within 1 sec thereafter. has exceeded 140C, but does not reach 150C within 1 sec thereafter. has exceeded 160C, but does not reach 165C within 1 sec thereafter

The fixing film unit is faulty (i.e., the main thermistor TH1 has poor contact, or the fixing heater is faulty). The main power supply PCB is faulty. The DC controller PCB is faulty. Caution To clear the error, execute the following in service mode: COPIER>FUNCTION>FCLEAR>ERR.

1. State Turn on the power switch, and clear E002/E003. Thereafter, turn off and then on the power switch. Does the fixing heater operate? NO: See “The fixing heater fails to operate.”

2. Wiring Is the wiring from the DC controller PCB to the fixing film unit normal? NO: Correct the wiring.

3. Fixing film unit, DC controller PCB Try replacing the fixing film unit. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.

E003-0000

The main thermistor reading is lower than 140C when paper is moved

The fixing film unit is faulty (i.e., the main thermistor (TH1) has poor contact or has an open circuit; or, the fixing heater is faulty). The main power supply PCB is faulty. The DC controller PCB is faulty. Caution To clear the error, execute the following in service mode: COPIER>FUNCTION>CLEAR>ERR

1. State Turn on the power switch, and clear E002/E003. Thereafter, turn off and then on the power switch. Does the fixing heater operate? NO: See “The fixing heater fails to operate.”

2. Wiring Is the wiring from the DC controller PCB to the fixing film unit normal? NO: Correct the wiring.

3. Fixing film unit, DC controller PCB Try replacing the fixing film unit. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.

E003-0001

An error in the rotation of the fixing film is detected. The reading of the main thermistor is 100C or higher and, in addition, the fixing film sensor does not detect the rotation of the film for 6 sec or more while the fixing motor is driven

The fixing film sensor (PS45) is faulty. The DC controller PCB is faulty. Caution To clear the error, execute the following in service mode: COPIER>FUNCTION>CLEAR>ERR

1. Wiring Are the wring and the connectors connected securely? DC controller PCB (J311) <-> relay connector <-> fixing film sensor NO: Connect the wiring and the connectors.

2. Fixing film sensor Check the fixing film rotation signal.When the fixing motor is rotating, is the film rotation detection signal sent by the fixing film sensor to the concoctor J311 of the DC controller PCB? Film rotation detection signal: 5V pulse signal between J311-A9 (FILM_ROT_D) and J311-A8 (GND); at intervals of 100 msec ON and 440 msec OFF NO: If the fixing film is normal, replace the sensor.
