Description: Fuser Agitator Fan Error
Causes: The Agitator Fan Rotation Feedback Signal (AGFAN_ST) continues to be H for more than 3seconds when the Agitator Fan is rotating.
Remedy: Wires 1 Are wires connected properly between Agitator Fan and DC Controller PCB? No Connect the wires properly. Driver PCB (PW0455) 2 Check the voltage at J61-3 of Driver PCB while Agitator Fan is working, whether it is 0V. No Replace Agitator Fan. Yes Replace Driver PCB (PW0455) DC Driver PCB (PW6650) 3 Enter the Service Mode and select the Function Checking Mode. Select the Sub Mode Number “3-39” and make the Agitator Fan work alone. While making the Agitator Fan work, check the voltage at J503-6 whether it is 0V. Yes Replace the DC Driver PCB (PW6650) with the new one. Agitator Fan (FAN2) 4 Check the voltage at J206-24 on the DC Controller PCB with a multi-meter. Is it 0V when the Agitator Fan is working? No Replace the Agitator Fan with the new one. Yes Replace the DC Controller PCB with the new one.
Code: E40
Description: Folder Error
Causes: Any error signal is inputted from the Folder Unit. (Door open or jam)
Remedy: Folder Unit (Option) 1 Is an error occurred on the optional Folder Unit? 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.
Code: E41
Description: Key Card Error
Causes: Key card is not set when Key Card Mode is selected.
Remedy: Key Card Unit 1 Is there any problem on the Key Card Unit? No Fix the problem. Service Mode 2 Is the setting of Key Card decided in the Service Mode proper? No Change the setting properly. Yes Replace the DC Controller with the new one.
Code: J-01
Description: 1st Roll Deck Jam
Causes: 1. The Paper Set Sensor Signal (RPSET1) does not change from H to L within a specified time since the machine has started feeding the 1st roll paper from the Roll Wait Position. 2. The Paper Set Sensor Signal (RPSET1) does not change from L to H within a specified time since the machine has started rewinding the 1st roll paper toward the Roll Wait Position.
Remedy: Setting condition of roll paper 1 Is the roll paper in the 1st Roll Deck set properly? No Set it properly. Paper Set Sensor 1 (PH1A) 2 Check the status of Paper Set Sensor Signal (RPSET1) in the Input / Output Checking Mode. (Signal Code of RPSET1 is “1- 81”.) Is it “L” when the roll paper is set? No 1. Check the wire of Paper Set Sensor 1. 2. If the wire has no problem, replace the Paper Set Sensor 1 with the new one. Paper End Clock Sensor (PH2A) 3 Confirm Clock Signal of Roll Paper (RPCLK1) using Input / Output Checking Mode. (Service Mode “1-80”) Signal “L” and “H” is indicated alternately, while Roll Paper is fed. 1. Check the Belt for Paper End Clock Sensor. 2. If the wire has no problem, replace the Paper End Clock Sensor. Roll Feed Motor (M2) 4 Draw out Roll Deck, turn Paper Feeding Roller Knob and feed paper approx. 20cm. Leave the tab of the Roll paper outside of the machine, close the Roll Deck. Is the Roll paper drew in approx. 5cm before “J-01” is indicated? No 1. If the wire has no problem, replace the Roll Feeder Board, ‘PW6623”. 2. Replace Roll Feed Motor, “M2”.
Code: J-02
Description: 2nd Roll Deck Jam
Causes: 1. The Paper Set Sensor Signal (RPSET2) does not change from H to L within a specified time since the machine has started feeding the 2nd roll paper from the Roll Wait Position. 2. The Paper Set Sensor Signal (RPSET2) does not change from L to H within a specified time since the machine has started rewinding the 2nd roll paper toward the Roll Wait Position.
Remedy: Setting condition of roll paper 1 Is the roll paper in the 2nd Roll Deck set properly? No Set it properly. Paper Set Sensor 2 (PH1B) 2 Check the status of Paper Set Sensor Signal (RPSET2) in the Input / Output Checking Mode. (Signal Code of RPSET2 is “83”.) Is it “L” when the roll paper is set? No 1. Check the wire of Paper Set Sensor 2. 2. If the wire has no problem, replace the Paper Set Sensor 2 with the new one. Paper End Clock Sensor (PH2B) 3 Confirm Clock Signal of Roll Paper (RPCLK1) using Input / Output Checking Mode. (Service Mode “1-82”) Signal “L” and “H” is indicated alternately, while Roll Paper is fed. 1. Check the Belt for Paper End Clock Sensor. 2. If the wire has no problem, replace the Paper End Clock Sensor. Roll Feed Motor (M2) 4 Draw out Roll Deck, turn Paper Feeding Roller Knob and feed paper approx. 20cm. Leave the tab of the Roll paper outside of the machine, close the Roll Deck. Is the Roll paper drew in approx. 5cm before “J-02” is indicated? No 1. If the wire has no problem, replace the Roll Feeder Board, ‘PW6623”. 2. Replace Roll Feed Motor, “M2”.
