Description: The edge gain correction level is different from the correction level for the preceding sheet by a specific level or more
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.
Code: E240-0000
Description: A fault occurs in communication between the CPU of the main controller PCB and the CPU of the DC controller PCB
Causes: The main controller PCB is faulty. The DC controller PCB is faulty.
Remedy: 1. Wiring Is the wiring from the min controller PCB to the DC controller PCB normal? NO: Correct the wiring. 2. DC controller PCB, Main controlled PCB Try replacing the DC controller PCB. Is the problem corrected? YES: End. NO: Replace the main controller PCB.
Code: E243-0000
Description: A fault occurs in the communication between the CPU of the control panel PCB and the CPU of the main controller PCB
Causes: The control panel CPU PCB is faulty. The main controller PCB is faulty.
Remedy: 1. Wiring Is the wiring from the main controller PCB to the DC controller PCB normal? NO: Correct the wiring. 2. Control panel CPU PCB, Main controller PCB Try replacing the control panel CPU PCB. Is the problem corrected? YES: End. NO: Replace the main controller PCB.
Code: E248-0001
Description: A difference is discovered between the ID in EEPROM read when the main power switch is turned on and the ID in ROM upon comparison
Causes: The EEPROM (IC403) of the reader controller PCB is faulty. The reader controller PCB is faulty.
Remedy: 1. Execute the following in service mode: COPIER>FUNCTION>CLEAR>CON. Is the proem corrected? YES: End. After executing the service mode, be sure to enter the service mode data newly. 2. EE-PROM, Reader controller PCB Try replacing the EE-PROM. Is the problem corrected? YES: End. After replacement, be sure to enter the service mode data newly. NO: Replace the rear controller PCB. After replacement, be sure to enter the service mode date newly.
Code: E248-0002
Description: The data read does not match the data written to EEPROM
Causes: The EEPROM (IC403) of the reader controller PCB is faulty. The reader controller PCB is faulty.
Remedy: 1. Execute the following in service mode: COPIER>FUNCTION>CLEAR>CON. Is the proem corrected? YES: End. After executing the service mode, be sure to enter the service mode data newly. 2. EE-PROM, Reader controller PCB Try replacing the EE-PROM. Is the problem corrected? YES: End. After replacement, be sure to enter the service mode data newly. NO: Replace the rear controller PCB. After replacement, be sure to enter the service mode date newly.
Code: E248-0003
Description: A difference is discovered between the ID of EEPROM and the ID of ROM upon comparison while writing data
Causes: The EEPROM (IC403) of the reader controller PCB is faulty. The reader controller PCB is faulty.
Remedy: 1. Execute the following in service mode: COPIER>FUNCTION>CLEAR>CON. Is the proem corrected? YES: End. After executing the service mode, be sure to enter the service mode data newly. 2. EE-PROM, Reader controller PCB Try replacing the EE-PROM. Is the problem corrected? YES: End. After replacement, be sure to enter the service mode data newly. NO: Replace the rear controller PCB. After replacement, be sure to enter the service mode date newly.
