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 (PW9650A) connected properly? No Connect the wires properly. Wire Cleaning Motor (M5) 2 Enter the Service Mode, select the Factory Adjustment Mode, and try to rotate the Wire Cleaning Motor. (Its Sub Mode Number is “04”.) Is the Wire Cleaning Motor rotated? No Replace the Wire Cleaning Motor with the new one. Yes Replace the Driver PCB (PW9650A) 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 rejected Thermostat with the new one. AC Terminal PCB (PW6610) 3 Check the voltage at J106-1 and J105-6 on the AC Terminal PCB with a multi-meter. Does the voltage of J105-6 show 0Vdc when that of J106-1 shows 24Vdc? No Replace the AC Terminal PCB with the new one. Yes Replace the DC Controller PCB with the 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 jammedunting.
Remedy: Outer Device 1 Is an error occurred 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 each Transmission PCB and Reception PCB. Can you fix the problem? Yes OK No Replace the DC Controller PCB with the new one. Service Mode “4-31” 4 Check the value of Service Mode “4-31”. In case Auto Stacker or Folder is not connected, it should be “0”.
Code: E-41
Description: Key Card Error (Option)
Causes: When Key Card is not inserted while Key Card is set.
Remedy: Key Card Unit (Option) 1 Is there any problem on the Key Card Unit? Yes Fix the problem. Service Mode 2 Check the value of Service Mode “4-30”. Is it “0” when Key Card is not connected? No Change the setting properly. Yes Replace the DC Controller with the new one.
Code: E-50
Description: Cassette Lift Error (Option)
Causes: When Cassette Deck is not lift up normally.
Remedy:
Code: E-51
Description: High Voltage Power Source Error
Causes: When output detection signal from HVP detects abnormal condition. Refer to page 7-25 for the detail.
Remedy: Feed Back Signal 1 Enter the Service Mode, select the Input / Output Checking Mode “1”, and check the status of feed back signal from High Voltage Power Supply. 1. HV Image Corona feed back (Its Signal Code is “38”.) 2. HV Transfer Corona feed back (Its Signal Code is “39”.) 3. HV Separation Corona feed back (Its Signal Code is “3A”.) 4. Dev Bias feed back (Its Signal Code is “3b”.) Is the status of feed back signal “H” when test print is taken? “H” = normal “L” = abnormal Yes Check if its load is leaked or not. Note: When the test print is finished, all of these items go back to “H”.
