Causes: After the Paper left the Exit Sensor, when “paper notexistence signal” is not received from Outer Device (Auto Stacker, Folder, etc.) within the specified time.
Remedy: Jam 1 Did a jam occur between the Outer Device (Auto Stacker, Folder, etc) and Exit Area? Yes 1. Remove the paper. 2. Adjust the height of the Outer Device.
Code: n01
Description: Toner Empty
Causes: 1. There is almost no toner available. 2. The Toner Cartridge being installed is considered to be invalid based on its IC Tag information.
Remedy: Toner Cartridge 1 Is the Toner Cartridge once emptied and reused? Yes Use a new, genuine Toner Cartridge. 2 Does the Toner Cartridge contain almost no toner in it? No Replace the Toner Cartridge with a new one. Toner Motor (M6) 3 Select Device Operation Mode, and try to make the Toner Motor work alone. (Signal Code: 2A) Is the Toner Motor rotated? No Check the wires among Toner Motor, Driver PCB (PW12050) and DC Controller PCB (PW12020). If there is no problem on wires, replace the Toner Motor with the new one. Toner Sensor (TLS1) 4 Check that the Toner Sensor is buried under the toner. Then, check the status of Toner Sensor in Device Status Mode. (Signal Code: 0E) Does is it “H” when TLS1 is covered with toner? And is it “L” when TLS1 is not covered with toner? No Replace the Toner Sensor with the new one. Yes Replace the DC Controller PCB (PW12020) with the new one.
Code: n02
Description: Roll Replacement
Causes: 1. No roll media is loaded on the selected Roll Number. 2. The roll media in the selected Roll Number is emptied. 3. There is no suitable roll media that are being required for the proceeding job.
Remedy: Roll media 1 Is there any suitable roll media that are being required for the proceeding job? ex) print job specifies “film” but no film in any Roll Decks No Load a suitable roll media to any Roll Deck. 2 Is a roll media in the selected Roll Deck emptied? Yes Load a new roll paper. Setting condition of roll paper 3 Is a roll media in the selected Roll Deck set correctly? Yes Set it correctly. Paper End Clock Sensor 4 Check the status of following sensors in Device Status Mode. 1. Roll Feed Sensor 1 (Signal Code: 51) 2. Roll Feed Sensor 2 (Signal Code: 53) 3. Roll Feed Sensor 3 (Signal Code: 55) 4. Roll Feed Sensor 4 (Signal Code: 57) Is the status switched between “H” and “L” when the roll paper is transported? No 1. Check whether the concerning roll media is set properly. 2. Check the wires of each sensor. 3. If there is no problem on media loading and wires, replace the abnormal sensor with a new one. Yes Replace DC Controller PCB (PW12020) with a new one.
Code: U-01
Description: Upper Roll Deck Open Error
Causes: The Upper Roll Deck is opened.
Remedy: Upper Roll Deck 1 Is the Upper Roll Deck opened? Yes Close it. Micro Switch (MS3A) 2 Check the status of Deck Switch 1 (MS3A) in Device Status Mode. (Signal Code: 4C) Is the status “L” when the Upper Roll Deck is closed? And is it “H” when the Upper Roll Deck is opened? No 1. Check the wire of Micro Switch (MS3A). 2. If the wire has no problem, replace the Micro Switch (MS3A) with the new one.
Code: U-02
Description: Lower Roll Deck Open Error
Causes: The Lower Roll Deck is opened.
Remedy: Lower Roll Deck 1 Is the Lower Roll Deck opened? Yes Close it. Micro Switch (MS3B) 2 Check the status of Deck Switch 2 (MS3B) in Device Status Mode. (Signal Code: 4D) Is the status “L” when the Upper Roll Deck is closed? And is it “H” when the Upper Roll Deck is opened? No 1. Check the wire of Micro Switch (MS3B). 2. If the wire has no problem, replace the Micro Switch (MS3B) with the new one.
Code: U-05
Description: Upper Frame Unit Open Error
Causes: Upper Frame Unit is opened.
Remedy: Upper Frame Unit 1 Is the Upper Frame Unit opened? Yes Close it. Micro Switch (MS2A, MS2B, MS2C) 2 Check the voltage at J112-7 on AC Terminal PCB (PW12010) with a multi-meter. (Check switches in the order as MS2A, MS2B and MS2C.) Is it 24Vdc? No Replace the defective switch with the new one. AC Terminal PCB (PW12010) 3 Check the voltage at J113-8 on AC Terminal PCB (PW12010) with a multi-meter. Device Status Mode Signal Code: 4A Is it 0Vdc? No Replace the AC Terminal PCB (PW12010) with the new one. DC Controller PCB (PW12020) 4 Check the voltage at J207-23 on DC Controller PCB (PW12020) with a multi-meter. Device Status Mode Signal Code: 4A Is it 0Vdc? No Replace the DC Controller PCB (PW12020) with the new one. Wires 5 Check the wires between AC Terminal PCB (PW12010) and DC Controller PCB (PW12020). Are wires connected properly? No Connect the wires properly Yes Replace the DC Controller PCB (PW12020) with the new one.
