Error Codes List page 1

  • Code: 13
  • Display: Paper Jam
  • Description: Defective during duplex-printing. Registration sensor detects paper feed condition at out of specified timing during switchback.
  • Remedy: - Check whether the recording paper being used is within the specification.
    1 Registration actuator caught on the surrounding parts Set the registration actuator into place. 2 Registration sensor defective Replace the registration sensor PCB ASSY. 3 Main PCB defective Replace the main PCB ASSY.
  • Code: 15
  • Display: Paper Jam
  • Description: Eject jam during printing. Recording paper is not able to be ejected since it is longer than 840 mm when ejecting the paper after occurrence of the error 17.
  • Remedy: - Remove the jammed paper. - Check if the recording paper used is according to specifications.
    1 Foreign materials in the recording paper path Remove foreign materials. 2 Main PCB defective Replace the main PCB ASSY.
  • Code: 17
  • Display: Paper size Mismatch
  • Description: Recording paper size error (duplex-printing/duplex-copying)
  • Remedy: - Check if the recording paper used is according to specifications. - Check if dark recording paper is not used.
    1 CR encoder strip stained Clean the CR encoder strip. 2 PF encoder disk stained Clean the PF encoder disk. 3 Registration actuator caught in the surrounding parts Set the registration actuator into place. 4 CR encoder strip defective Replace the CR encoder strip. 5 PF encoder disk defective Replace the PF encoder disk. 6 Registration sensor defective Replace the registration sensor PCB ASSY. 7 Paper width sensor defective Replace the carriage PCB ASSY. 8 Paper feed motor defective Replace the paper feed motor. 9 Main PCB defective Replace the main PCB ASSY.
  • Code: 18
  • Display: Paper Jam
  • Description: Paper jam during duplex-printing. The registration sensor does not detect paper feed within specified pulse numbers in the second side paper re-feed.
  • Remedy: - Remove the jammed recording paper. - Check if the recording paper used is according to specifications. - Check if the recording paper is not curled, wrinkled or wet.
    1 Foreign materials in the duplex print paper path Remove foreign materials. 2 Registration actuator caught in the surrounding parts Set the registration actuator into place. 3 Registration sensor defective Replace the registration sensor PCB ASSY. 4 Main PCB defective Replace the main PCB ASSY.
  • Code: 20
  • Display: Cannot Detect
