Description: The motor ready signal does not arrive within 15 sec after the laser scanner motor drive signal is generated
Causes: The wiring is faulty (short circuit, open circuit, disconnection). The laser scanner motor (M10) is faulty. The main power supply PCB is faulty. The DC controller PCB is faulty.
Remedy: 1. Connector Are the connector (J312) on the DC controller PCB and the relay connector connected securely? NO: Connect the connectors securely. 2. Main power supply PCB During printing, does the voltage between J204-1 (+) and J204-2 (-) on the main power supply PCB change from 0 to about 24 V? NO: Replace the main power supply PCB. 3. Laser scanner unit, DC controller PCB Try replacing the laser scanner unit. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.
Code: E202-0001
Description: The scanner home position sensor does not go OFF when the scanner is moved forward by 40 mm
Causes: The scanner home position sensor (PS400) is faulty. The scanner motor (M400) is faulty. The reader controller PCB is faulty.
Remedy: 1. State Does the scanner operate when the power is turned on? NO: See 4.2.9 The No. 1 mirror base does not operate. 2. Scanner home position sensor (PS400), Reader controller PCB Move the No. 1 mirror base by hand from home position. Does the output of the scanner home position sensor change? (J405-2 on the reader controller PCB is 5 V (in HP) or 0V (away from HP)) NO: Replace the sensor. YES: Replace the rear controller PCB.
Code: E202-0002
Description: The scanner home position sensor does not go ON when the scanner is moved reverse 450 mm
Causes: The scanner home position sensor (PS400) is faulty. The scanner motor (M400) is faulty. The reader controller PCB is faulty.
Remedy: 1. State Does the scanner operate when the power is turned on? NO: See 4.2.9 The No. 1 mirror base does not operate. 2. Scanner home position sensor (PS400), Reader controller PCB Move the No. 1 mirror base by hand from home position. Does the output of the scanner home position sensor change? (J405-2 on the reader controller PCB is 5 V (in HP) or 0V (away from HP)) NO: Replace the sensor. YES: Replace the rear controller PCB.
Code: E204-0001
Description: While an original is being read, the image leading edge signal does not arrive from the ADF
Causes: The ADF controller PCB is faulty. The reader controller PCB is faulty. Caution When this code occurs, no code is indicated, but the keys are locked. The code may be checked in service mode: COPIER>DISPLAY>ERR.
Remedy: 1. Read sensor (S2) Try replacing the read sensor of the ADF. Is the problem corrected? YES: End. 2. ADF controller PCB, Reader controller PCB Try replacing the ADF controller PCB. Is the problem corrected? YES: End. NO: Replace the reader controller PCB.
Code: E220-0001
Description: A fault is detected on the inverter PCB for the scanning lamp
Causes: The inverter PCB is faulty. The reader controller PCB is faulty.
Remedy: 1. Wiring Is the wiring from the scanning lamp to the reader controller PCB normal? NO: Connect the connector firmly, and correct or replace the wiring. 2. Inverter PCB, Reader controller PCB Try replacing the lamp inverter PCB. Is the problem corrected? YES: End. NO: Replace the reader controller PCB.
Code: E225-0000
Description: A specific level cannot be attained for the signal during CCD gain correction at power-on
Causes: The scanning lamp is faulty. The CCD PCB is faulty. The rear controller PCB is faulty.
Remedy: 1. Scanning lamp (LAMP1) Is the lamp ON during the initial operation after the main power switch is turned on? NO: Replace the scanning lamp. 2. CCD unit, Reader controller PCB Try replacing the CCD unit. Is the problem corrected? YES: End. NO: Replace the reader controller PCB.
