Sharp AR5623DA Error Codes List page 1 from 4

  • Code: CH Blink
  • Description: Developing cartridge not installed. The developing cartridge is not installed. Communication with the CRUM cannot be made in initial check of the CRUM.
  • Causes: Developing unit disconnection MCU PWB abnormality CRUM chip abnormality
  • Remedy: Check installation of the developing unit. Replace the MCU PWB.
  • Code: CH ON
  • Description: Side door open. The side door is open.
  • Causes: Side door sensor abnormality MCU PWB abnormality
  • Remedy: Check that all the side doors are closed. Replace the MCU PWB.
  • Code: E7 01
  • Description: Duplex model memory error/ Image data error. 1. The memory capacity for the duplex model machine is wrong. Insufficient memory capacity. 2. Duplex setting is set for a single surface model.
  • Causes: 1. The memory capacity on the MCU PWB is wrong. 2. Setting for a single surface model is wrong.
  • Remedy: 1. Use SIM26-39 to check to confirm that the memory capacity is 64MB. If it is not 64MB, replace the MCU PWB. 2. If SIM26-04 is set to 1, change the setting to 0. If it is 0, replace the MCU PWB.
  • 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.
  • Code: E7 06
  • Description: Image data decode error. Image expansion error
  • Causes: MCU PWB abnormality USB cable trouble
  • Remedy: Replace the MCU PWB. Replace the USB cable.
  • 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.
  • Remedy: Check connection of the CCD unit flat cable. Check the CCD unit.
  • 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 scan position.) Improper installation of the mirror unit
  • Remedy: Clean the mirror, the lens, and the reference white plate. Check lighting and the light quantity of the copy lamp (SIM05-03). Check the CCD unit. Check the MCU PWB.
  • Code: E7 16
  • Description: Abnormal laser output. When the laser output is stopped, HSYNC is detected.
  • Causes: Laser abnormality MCU PWB abnormality.
  • Remedy: Replace the LSU. Replace the MCU PWB.
