• Code: 33
• Description: JAM 2 1. Recording paper is jammed in front of or inside the fuser. 2. Recording paper is stuck in the discharge roller and in the fuser just after passing through the Actuator-Feed.
• Causes: 1. If the paper is completely fed out of the printer, but Jam 2 occurs: The Exit sensor may be defective. • After the paper is completely discharged the Exit sensor actuator should return to its original position to shut the photo-sensor. It may stick open or return only slowly due to contamination be paper debris or foreign objects. 2. If the paper is rolled in the Fuser Roller: • This occurs when a Guide claw is broken away, damaged or deformed. • It occurs when the Spring of a Guide claw is broken or damaged. • It occurs when the Heat-Roller or Pressure-Roller is seriously contaminated with toner.
• Remedy: 1. Check if the exit sensor actuator is defective. • Check if the actuator exit is deformed (Check if the lever part is deformed). • Check whether burrs occur in the assembly part of the exit actuator and if the actuator operates smoothly. • Check if foreign objects or paper debris are preventing the correct operation of the actuator. 2. If the paper is stuck in the fuser : disassemble the fuser and remove the jammed paper, and clean the surface of the pressure roller with dry gauze. Check all ribs, claws and springs.

• Code: 34
• Description: Multi-Feeding Multiple sheets of paper are fed at once.
• Causes: 1. Check that the paper size guides are set correctly (cassette and MPF tray). 2. Solenoid malfunction (the solenoid does not work properly). 3. Friction Pad is contaminated. 4. Paper has a rough surface texture.
• Remedy: 1. Adjust paper guides. 2. Replace the solenoids or PBA as appropriate. 3. Clean the friction pad rubber with a soft cloth dampened with IPA (Isopropyl Alcohol) or water. 4. Use paper with a smother surface finish.

• Code: 35
• Description: Paper rolled in the fuser Paper rolled around fuser rollers or ‘Concertina’ jam
• Causes: 1. Contamination of the pressure roller or heat roller. 2. Damaged or deformed ribs, claws or springs.
• Remedy: 1. After disassembling the fuser, clean contamination from between the heat roller and the thermistor and also clean contamination from the pressure roller. Clean the surface of the rollers with IPA or water 2. Check for damage or deformation of the print claws and the holder plate claws, and repair or replace as appropriate.

• Code: 36
• Description: Paper rolled on the OPC Drum Paper is rolled up in the OPC.
• Causes: 1. Paper is too thin. 2. The face of paper is curled.
• Remedy: 1. Use paper that conforms to the printer specification. 2. Ensure paper is stored properly to prevent curl. Note. To remove paper rolled in the OPC. • Remove the toner cartridge from the set, taking care not to touch the green surface. Use the gearwheel at the side to rotate the OPC drum and pull the paper from the cassette. • Clean fingerprints on the OPC gently with soft tissue, taking care not to scratch the surface.

• Code: 37
• Description: Fuser Error A message "Open Heat Error/Over heat/Heating Error' is displayed in the LCD panel.
• Causes: 1. Thermostat, fuser power cable or heat lamp is open circuit. 2. Thermistor is open circuit. 3. Heat lamp ON/OFF test 4. Drive gear melted
• Remedy: 1. Replace the whole fuser assembly if the thermostat is open circuit. 2. Replace the whole fuser assembly if the thermistor sensor is faulty. 3. Replace the fuser

• Code: 38
• Description: LSU Error A message "PMOTOR ERROR/HSYNC ERROR' is displayed in the LCD panel.
• Causes: 1. LSU cable or connector faulty. 2. LSU motor is faulty. 3. Check the HSYNC signal.
• Remedy: Use TECH mode to test the LSU - Replace the LSU - Replace a main board if the same error persists after replacing a LSU.

• Code: 39
• Description: Fuser gear melts due to overheating causing Paper Jam. Constant Jam where paper is entering Fuser unit. Fuser rollers do not turn
• Causes: 1. Check the Heat Lamp, thermostat and thermistor
• Remedy: 1. Use EDC Mode to test the fuser. Replace Fuser unit Replace SMPS or Main PBA as appropriate.

• Code: 40
• Description: Paper Empty Paper Empty is displayed in the LCD panel even when paper is loaded in the cassette.
• Causes: 1. Deformed paper sensor actuator or faulty sensor. 2. SMPS PBA or Main PBA is defective 3. Faulty cables or connectors.
• Remedy: 1. Replace the defective actuator or sensor. 2. Replace the SMPS PBA or MAIN PBA as appropriate.
