Causes: 1. The Cutter Home Sensor Signal (MSCUT_L or MSCUT_R) does not change to “H” within 100 millisecond since the Cutter has started the operation. 2. The Cutter Home Sensor Signal (MSCUT_L or MSCUT_R) does not change to “L” within 1 second since the Cutter has started the operation.
Remedy: Wires 1 Is the wire between Cutter Unit and PW11720 PCB connected properly? No Connect it properly. Cutter Home Position Sensors (MS8 & MS9) 2 Check the status of the following signals in the Signal Status Mode of the Service Mode. Signal Code : 094 (Cutter Home Position Right) 095 (Cutter Home Position Left) Is the status “L” when the Cutter is at each home position? No Replace the Cutter Unit. Cutter Motor (M4) 3 Check the operation of Cutter in the Operation Check Mode of the Service Mode. Device Code : 27 (Cutter Motor 1) 28 (Cutter Motor 2) Does the Cutter operate? No Replace the Cutter Unit.
Code: E-0050
Description: FPGA Error
Causes: Initialization of FPGA is failed after turning on.
Remedy: PW11720 PCB 1 Can you fix the problem if you replace the PW11720 PCB? Yes OK
Code: E-0070
Description: Developer Error
Causes: 1. The Connector J-253 is not connected. 2. The Switch (MS4) is “open” condition, which detects open/close of Engine Unit or Toner Hatch.
Remedy: Wires 1 Is the wire between Developer Unit and PW11720 PCB connected properly? No Connect it properly.
Code: E-0080, E-0081
Description: Density Sensor Error
Causes: Density Sensor cannot be calibrated correctly before Density Measure.
Remedy: Wires 1 Is the wire between Toner Density Sensor and PW11720 PCB connected properly? No Connect it properly. Density Sensor (PH8) 2 Can you fix the problem if you replace Density Sensor? No Replace PW11720 with a new one.
Code: E-0090
Description: Eraser Lamp Error
Causes: 1. The connector J-227 / J-228 is not connected. 2. Eraser Lamp (PW6631) is broken.
Remedy: Wires 1 Is the wire between Toner Density Sensor and PW11720 PCB connected properly? Is the spring on the left bottom of the Process Unit OK? No Connect it properly. Eraser Lamp 2 Can you fix the problem if you replace the Process Unit? No Replace PW11720 with a new one.
Code: J-0103, J-0203
Description: Roll Deck Feeder Jam
Causes: Delay : Paper arrives the sensor much later than required timing. Stay : Paper exists on the sensor for longer time than required. Remained : Paper has already existed on the sensor when turning on the machine.
Remedy: Mis-feed of paper 1 Does the paper mis-fed occur between Roll Set Sensor and Feed Sensor? Yes Remove the mis-fed paper. Manual Feed Sensor (PH7) 2 Check the status of Feed Sensor in the Signal Status Mode of the Service Mode. Signal Code : 008 (Manual Feed Sensor) Is the status “L” when the paper is not passing beside the sensor? And is it “H” when the paper is passing beside the sensor? No 1. Is there any problem with the Drawer Connector which connects the machine and the Roll Deck. 2. Check if there is any problem with the wire connected to the Feed Sensor. 3. Replace the Manual Feed Sensor if there is no problem with the wire. Cutter Home Position Sensor (MS8 & MS9) 3 Check the status of Cutter Home Position Sensors in the Signal Status Mode of the Service Mode. Signal Code : 094 (Cutter Home Position Right) 095 (Cutter Home Position Left) Is the status “H” when the Cutter is at each home position? And is it “L” when the Cutter is not at the home position? No 1. Check if there is any problem with the wire connected to the Cutter Home Position Sensor. 2. Replace the Cutter Home Position Sensors if there is no problem with the wire. Driving mechanism 4 Check the operation of Feed Clutch in the Operation Check Mode of the Service Mode. Device Code : 10 (Feed Clutch) Open and close Roll Deck and check if Main Motor rotates correctly. Does each Feed Clutch and Main Motor operate correctly? No Replace the Feed Clutch or Main Motor if it is defective.
