Causes: The Paper Exit Sensor Signal (P_EXIT) does not change from L to H within a specified time since the machine has started feeding the paper from the Paper Entry Position.
Remedy: 1 Did a jam occur at the Exit Area? Yes Remove the paper. Sensor (PH8) 2 Select the Input / Output Checking Mode, and check whether or not the following sensor work properly. 1. Paper Exit Sensor (Signal Code is “2F”.) Is the status “L” when the sensor does not detect the paper? And is it “H” when the sensor detects the paper? No 1. Check the wire of sensor. 2. If the wire has no problem, replace the sensor with the new one. Driving part (SL1) 3 Select the Function Checking Mode, and try to make the following part work alone. 1. Fuser Shutter Solenoid (Signal Codes are “4C” and “4D”.) CAUTION Do not make the above signals be “H” for more than 10 seconds because the Fuser Shutter Solenoid may be broken. Is the Fuser Shutter moved? No Replace the Fuser Shutter Solenoid with the new one. Clean the Fuser Shutter.
Code: J-14
Description: Exit Area Jam (Stay)
Causes: 1. The Paper Exit Sensor Signal (P_EXIT) is H at the time you turn on the machine. 2. The Paper Exit Sensor Signal (P_EXIT) once changes from L to H during printing. But after that it does not change from H to L within a specified time since the Paper Gate Sensor Signal (P_GATE) has changed from L to H. 3. The Paper Transportation Signal (P_TRANS) is stable for a specified time and also the Paper Transportation Error Signal (RY_ST) changes from L to H when the paper is going through the Transportation Detection Area.
Remedy: Jam 1 Did a jam occur between Separation Area and Exit Area? Yes Remove the paper. Sensor (PH8) 2 Select the Input / Output Checking Mode, and check whether or not the following sensor work properly. 1. Paper Exit Sensor (Signal Code is “2F”.) Is the status “L” when the sensor does not detect the paper? And is it “H” when the sensor detects the paper? No 1. Check the wire of sensor. 2. If the wire has no problem, replace the sensor with the new one. Detection of paper transportation (PH9 and PW6650) 3 Check the signal of the following points with a multi-meter rotating the Paper Transportation Roller. 1. J45-2 of Paper Transportation Sensor (PH9) 2. J502-8 of the DC Driver PCB (PW6650) Is a clock pulse outputted from these points? No 1. Check the connector of the Sensor. 2. Replace either Paper Transportation Sensor or DC Driver PCB (PW6650) with the new one.
Code: n01
Description: Toner Low
Causes: The quantity of toner becomes smaller than a specified level.
Remedy: Quantity of toner in the Hopper 1 Is there enough toner in the Hopper? No Supply the Hopper with the toner. Toner Motor (M5) 2 Select the Function Checking Mode, and try to make the Toner Motor work alone. (Its Signal Code is “3-3C”.) Is the Toner Motor rotated? No Check the wires among Toner Motor, DC Controller PCB and Driver PCB (PW6654). If there is no problem on wires, replace the Toner Motor with the new one. Toner Sensor (TLS1) 3 Confirm that the Toner Sensor is buried under the toner. Then, enter the Service Mode and select the Analog Data Checking Mode. Select the Sub Mode Number “2-0C” to check the analog voltage sent from the Toner Sensor. Is it 5.00V or near value? No Replace the Toner Sensor with the new one. Yes Replace the DC Controller PCB with the new one.
Code: n02
Description: Roll Empty
Causes: 1. No roll paper is loaded on the selected Roll Deck. 2. The roll paper in the selected Roll Deck is emptied while printing or detecting the roll paper size.
Remedy: Roll paper 1 Is the roll paper in the selected Roll Deck emptied? Yes Load a new roll paper. Setting condition of roll paper 2 Is the roll paper in the selected Roll Deck slackened too much? Yes Set it properly. Paper End Clock Sensor 3 Select the Input / Output Checking Mode, and check whether or not the following sensors work properly. 1. 1st Paper End Clock Sensor (Signal Code is “1-80”.) 2. 2nd Paper End Clock Sensor (Signal Code is “1-82”.) 3. 3rd Paper End Clock Sensor (Signal Code is “1-84”.) 4. 4th Paper End Clock Sensor (Signal Code is “1-86”.) Is the status switched between “H” and “L” when the roll paper is transported? No 1. Check whether or not the Roll Paper Spool is set properly. 2. Check the wires of each sensor. 3. If there is no problem on Roll Paper Spool and wires, replace the defective sensor with the new one. Yes Replace either Roll Feeder PCB (PW6623) or DC Controller PCB (PW6620) with the new one.
Code: U-01
Description: 1st Roll Deck Open Error
Causes: The 1st Roll Deck is opened.
Remedy: 1st Roll Deck 1 Is the 1st Roll Deck opened? Yes Close it. Micro Switches (MS4A and MS4B) 2 Is each Micro Switch firmly pressed when you close the 1st Roll Deck? No Replace the Micro Switch. Yes Install the 1st Roll Deck to the machine properly. Roll Feeder PCB (PW6623) 3 Check the voltage at J253-2 on the Roll Feeder PCB with a multi-meter. Is it 0V when the 1st Roll Deck is closed? No Check whether or not any wire is broken between Roll Feeder PCB and Micro Switches (MS4A and MS4B). Yes Replace the Roll Feeder PCB with the new one.
Code: U-02
Description: 2nd Roll Deck Open Error
Causes: The 2nd Roll Deck is opened.
Remedy: 2nd Roll Deck 1 Is the 2nd Roll Deck opened? Yes Close it. Micro Switches (MS5A and MS5B) 2 Is each Micro Switch firmly pressed when you close the 2nd Roll Deck? No Replace the Micro Switch. Yes Install the 2nd Roll Deck to the machine properly. Roll Feeder PCB (PW6623) 3 Check the voltage at J253-4 on the Roll Feeder PCB with a multi-meter. Is it 0V when the 2nd Roll Deck is closed? No Check whether or not any wire is broken between Roll Feeder PCB and Micro Switches (MS5A and MS5B). Yes Replace the Roll Feeder PCB with the new one.
