• Code: E7-10
• Description: Shading trouble (Black correction)
  The CCD black scan level is abnormal when the shading.
• Causes: Improper connection of the CCD unit flat cable CCD unit abnormality MCU PWB abnormality

• Code: E7-11
• Description: Shading trouble (White correction)
  The CCD white scan level is abnormal when the shading.
• Causes: Improper connection of the CCD unit flat cable Dirt on the mirror, the lens, and the reference white plate Copy lamp lighting abnormality CCD unit abnormality MCU PWB abnormality (When occurred in the SPF/RSPF scan position.) Improper installation of the mirror unit

• Code: E7-16
• Description: Abnormal laser output
  When the laser output is stopped, HSYNC is detected.
• Causes: Laser abnormality MCU PWB abnormality.

• Code: F5-02
• Description: Copy lamp lighting abnormality
  The copy lamp does not turn on.
• Causes: Copy lamp abnormality Copy lamp harness abnormality CCD PWB harness abnormality.

• Code: H2-00
• Description: Thermistor open
  The thermistor is open. The fusing unit is not installed.
• Causes: Thermistor abnormality Control PWB abnormality Fusing section connector disconnection The fusing unit is not installed.

• Code: H3-00
• Description: Heat roller high temperature detection
  The fusing temperature exceeds 240°C.
• Causes: Thermistor abnormality Control PWB abnormality Fusing section connector disconnection.

• Code: H4-00
• Description: Heat roller low temperature detection
  1) When the target temperature (165°C) is not reached in 55 sec after starting warming-up. 2) When the temperature below 100°C is detected for 300ms under the ready print state. "Starting warming-up" means not only that in power supply but also reset that in reset from shut-off and in side door close. (The timing of generating H4 is not limited to that in power supply.)
• Causes: Thermistor abnormality Heater lamp abnormality Thermostat abnormality Control PWB abnormality

• Code: L1-00
• Description: Feeding is not completed within the specified time after starting feeding. (The scan head locking switch is locked)
  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.
• Causes: The scan head is locked by the lock switch. Mirror unit abnormality The scanner wire is disconnected. The origin detection sensor abnormality Mirror motor harness abnormality
