Causes: An abnormality occurs in communication between the CPU and the IMC.
- Replace the MCU PWB with new one.
Causes: An abnormality occurs in the IMC.
- USB chip error/CODEC error on the IMC.
- Replace the MCU PWB with a new one.
Causes: An abnormality occurs in the IMC flash ROM.
- Replace the MCU PWB with a new one. If downloading of the program is abnormally terminated, it may cause an error. Download the program again to avoid this.
Causes: An installation error occurs in the IMC memory module.
An error occurs during access to the IMC memory.
- Improper installation of the IMC memory module.
Causes: A parity error occurs in communication between the CPU and the IMC.
Causes: An overrun error occurs in communication between the CPU and the IMC.
- IMC memory defect/data abnormality.
Causes: A framing error occurs in communication between the CPU and the IMC.
Causes: The CCD black scan level is abnormal when the shading.
Causes: The CCD white scan level is abnormal when the shading.
Causes: When the laser output is stopped, HSYNC is detected.
- Laser abnormality MCU PWB abnormality.
Causes: The copy lamp does not turn on.
- CCD PWB harness abnormality.
Causes: The thermistor is open.
The fusing unit is not installed.
- The fusing unit is not installed.
Causes: The fusing temperature exceeds 240°C.
- Fusing section connector disconnection.
Causes: The fusing temperature does not reach 185°C within 27 sec of turning on the power, or the fusing temperature keeps at 140°C.
Causes: The white area and the black marking on the shading plate are used to obtain the difference in the CCD level values for judgment of lock. When the difference in the levels of which and black is small, it is judged that the black mark could not be scanned by lock and the trouble code “L1” is displayed.
- The scan head is locked by the lock switch.
- The scanner wire is disconnected.
Causes: When the main motor encoder pulse is not detected for 100 msec.
- Improper connection or disconnection the main motor and the harness.
Causes: The lock signal (specified rpm signal) does not return within a certain time (about 20 sec) from starting the polygon motor rotation.
- Improper connection or disconnection of the polygon motor and the harness.
- The SRAM backup battery voltage on FAX PWB falls.
Causes: There is no language file.
The language file is destroyed.
