Description: The rotation of the laser motor cooling fan is faulty.
The lock signal arrives for 5 sec or more although the laser motor cooling fan (FM1) is being driven.
Remedy: - Check if there is no foreign material in the rotation assembly of the laser motor cooling fan. - Check if the connector (J503) of the relay PCB is mounted properly. - Replace the laser motor cooling fan. - Replace the DC controller PCB.
Code: E121-0001
Description: The rotation of the laser cooling fan (1/2) is faulty.
The lock signal arrives for 5 sec or more although the laser cooling fan 1 (FM3) is being driven.
Remedy: - Check if there is no foreign material in the rotation assembly of the laser cooling fan 1. - Check if the connector (J503) of the relay PCB is mounted properly. - Replace the laser cooling fan 1. - Replace the DC controller PCB.
Code: E121-0002
Description: The rotation of the laser cooling fan (1/2) is faulty.
The lock signal arrives for 5 sec or more although the laser cooling fan 2 (FM5) is being driven.
Remedy: - Check if there is no foreign material in the rotation assembly of the laser cooling fan 2. - Check if the connector (J503) of the relay PCB is mounted properly. - Replace the laser cooling fan 2. - Replace the DC controller PCB.
Code: E202-0000
Description: There is an error in the detection of the scanner home position.
Scanner home position cannot be detected within a specific period of time after the power switch is turned on or the Start key is pressed.
Remedy: Caution No code will be indicated. The keys will be locked. You can check the code in service mode (COPIER>DISPLAY>ERR). - Check if the scanner motor is connected properly, and replace the scanner motor if necessary. - Check if the connector (J1720) of the relay PCB is mounted properly. - Replace the scanner home position sensor. - Replace the reader controller PCB.
Code: E204-0000
Description: There is an error in the detection of the image leading edge signal.
During forward movement in fixed reading mode or during a home position search, the image leading signal does not occur; or, in stream reading mode, the image leading edge signal does not arrive from the ADF controller PCB.
Remedy: Caution No code will be indicated. The keys will be locked. You can check the code in service mode (COPIER>DISPLAY>ERR). - Check if the scanner motor is connected properly, and replace the scanner motor if necessary. - Replace the scanner image leading edge sensor. - Replace the reader controller PCB.
Code: E211-0000
Description: The rise in temperature of the scanning lamp heater is faulty.
While the power is ON, the ambient temperature of the scanning lamp does not exceed 10 deg C 2 min after the florescent heater has gone ON; or, after the power is turned on, the reading of the ambient temperature of the scanning lamp is 0 deg C or lower.
Remedy: - Check if the connecter (J852, J853) of the light control PCB is mounted properly. - Replace the scanning lamp heater. - Replace the light control PCB. - Replace the reader controller PCB.
