Causes: When Fuser Motor Speed Detection Signal (FUMTR_LD) remains H more than 3 seconds while Fuser Motor is rotating.
Remedy: Wires 1 Are wires connected properly between Fuser Motor and DC Controller? No Connect the wires properly. Fuser Motor (M4) 2 Select Device Operation Mode, and try to make the Fuser Motor work alone. (Signal Code: 86) Is the Fuser Motor rotated? No Replace Fuser Motor or DC Controller PCB (PW12020) with the new one.
Code: E-16
Description: Wire Cleaning Error
Causes: The Wire Cleaning Motor Over Current Signal (WCMTR_OC) remains H for more than 90 seconds during wire cleaning.
Remedy: Wires 1 Are wires between Imaging Charger and Driver PCB (PW12051) connected properly? No Connect the wires properly. Wire Cleaning Motor (M5) 2 Select Device Operation Mode, and try to rotate the Wire Cleaning Motor. (Signal Code: 88) Is the Wire Cleaning Motor rotated? No Replace the Wire Cleaning Motor with the new one. Yes Replace the Driver PCB (PW12051) with the new one.
Code: E-21
Description: Fuser Thermostat Error
Causes: 1. When the Thermostat is cut off. 2. When Interlock Signal (INTLK1) changes to H.
Remedy: Wires 1 Are wires connected properly among Thermostat, AC Terminal PCB and DC Controller PCB? No Connect the wires properly. Thermostat (TS1A, TS1B) 2 Check the resistance of the Thermostat. Is there any resistance? No Replace the Thermostat with the new one. AC Terminal PCB (PW12010) 3 Check the voltage at J112-1 and J113-6 on the AC Terminal PCB with a multi-meter. Does the voltage of J113-6 show 0Vdc when that of J112-1 shows 24Vdc? No Replace the AC Terminal PCB (PW12010) with the new one. Yes Replace the DC Controller PCB (PW12020) with the new one. Fuse PCB (PW9690) 4 Check the voltage at J902B-1 and Fuse F901 with a multimeter. Is it 24Vdc? No Replace F901 with a new one. 5 Check the voltage at J208 on DC Controller PCB (PW12020). Is it 24Vdc? No Connect the wires properly.
Code: E-27
Description: Density Sensor Errori
Causes: Density Sensor (PH10) failed its initialization because of an abnormal output.
Remedy: Wires 1 Is the wire between Density Sensor and DC Controller PCB (PW12020) connected properly? Yes Connect the wires properly. Density Sensor (PH10) 2 Can you fix the problem if you replace Density Sensor? No Replace DC Controller PCB (PW12020) with a new one.
Code: E-40
Description: Outer Device Error
Causes: 1. When Error is received while the Outer Device (Auto Stacker, Folder, etc.) is connected. 2. When the Door of the Outer Device (Auto Stacker, Folder, etc.) is opened, or the Outer Device is jammed.
Remedy: Outer Device 1 Did an error occur on the Outer Device (Auto Stacker, Folder, etc.) connecting to the printer as the option? Yes Clear the error. Wires 2 Are wires connected properly among Transmission PCB, Reception PCB and DC Controller PCB? No Connect the wires properly. Transmission PCB (PW5490) Reception PCB (PW5491) 3 Try to replace Transmission PCB or Reception PCB. Can you fix the problem? Yes OK No Replace the DC Controller PCB (PW12020) with the new one. Adjustment Mode No.31. 4 Check for Adjustment Mode No.31. In case Auto Stacker or Folder is not connected, it should be “0”.
Code: E-43
Description: RFID Error
Causes: 1. IC-TAG R is defective. 2. Connection between PW12020 and IC-TAG R is defective
Remedy: Wires 1 Is the wire between IC-TAG R and DC Controller PCB (PW12020) connected properly? Yes Connect the wires properly. IC-TAG R (RFID) 2 Can you fix the problem if you replace IC-TAG R? No Replace DC Controller PCB (PW12020) with a new one.
