  • Code: E7-01
  • Description: Duplex model memory error
    The memory capacity for the duplex model machine is improper. Insufficient memory capacity
  • Causes: The memory capacity of the MCU PWB is improper.
  • Remedy: Set SIM 26-39 code number to 2.
  • Code: E7-02
  • Description: LSU trouble
    The BD signal from the LSU cannot be detected in a certain cycle. (Always OFF or always ON)
  • Causes: LSU connector or LSU harness defect or disconnection Polygon motor rotation abnormality Laser beams are not generated. MCU PWB abnormality.
  • Remedy: Check connection of the LSU connector. Execute SIM 61-03 to check the LSU operations. Check that the polygon motor rotates normally. Check that the laser emitting diode generates laser beams. Replace the LSU unit. Replace the MCU PWB.
