Description: The intervals of zero-cross signals deviate from the tolerance range while the fixing heater is supplied with power
Causes: The wiring is faulty (short circuit, open circuit). The main power supply PCB is faulty. The DC controller PCB is faulty.
Remedy: 1. Connectors Are the connector J205 on the main power supply PCB and the connector J308B on the DC controller PCB securely connected? (zero-cross signal: J205-7 <-> J308B-1) NO: Connect the connectors securely. 2. Main power supply PCB, Main controller PCB Try replacing the main power supply PCB. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.
Code: E302-0001
Description: During shading, the shading processing does not end on the reader controller PCB after 1 sec
Causes: The CCD PCB is faulty. The wiring is faulty (short circuit, open circuit). The reader controller PCB is faulty.
Remedy: 1. Connector Are the connectors (J6001/J6002) on the CCD PCB and the connectors (J5002/J5003) on the reader controller PCB connected securely? NO: Connect the connectors securely. 2. CCD unit Try replacing the CCD unit. Is the problem corrected? YES: End. 3. Reader controller PCB, Main controller PCB Try replacing the reader controller PCB. Is the problem corrected? YES: End. NO: Check the wiring; if normal, replace the main controller PCB.
Code: E302-0002
Description: During stream reading, the edge white addition processing does not end on the rear controller PCB after 10 sec
Causes: The CCD PCB is faulty. The wiring is faulty (short circuit, open circuit). The reader controller PCB is faulty
Remedy: 1. Connector Are the connectors (J6001/J6002) on the CCD PCB and the connectors (J5002/J5003) on the reader controller PCB connected securely? NO: Connect the connectors securely. 2. CCD unit Try replacing the CCD unit. Is the problem corrected? YES: End. 3. Reader controller PCB, Main controller PCB Try replacing the reader controller PCB. Is the problem corrected? YES: End. NO: Check the wiring; if normal, replace the main controller PCB.
Code: E315
Description: Any of the following is true in the image processing by the main controller:
The image data has a fault The encoding/decoding operation for image data has a fault The image processing element of the main controller PCB has a fault
Causes: The image data is faulty. The main controller PCB is faulty. The HDD is faulty.
Remedy: If this error occurs during normal copying or printing, the job in question (image data) is cleared when the main power switch is turned off and then on again; i.e., the machine will be reset. If this error occurs frequently, however, a fault on the main controller PCB is a possibility. Further, if this error occurs in a specific image within the MAIL BOX, damage in data may be assumed; be sure to delete the image from the MAIL BOX.
Code: E420-0001
Description: When the power switch of the host machine is turned on, the back-up data from the EEPROM cannot be read or the data that has been read has a fault
Causes: The EEPROM is faulty. The ADF controller PCB is faulty.
Remedy:
Code: E421-0001
Description: The back-up data cannot be written to the EEPROM, or the data that has been written has a fault
Causes: The EEPROM has a fault. The ADF controller PCB has a fault.
