Causes: 1. When the temperature of the heat roller does not go up by the specified value for 22 to 40 seconds after warm-up is started. Same can be said for the pressure roller temperature. 2. When the temperature of the pressure roller does not reach 80°C for 90 seconds after warm-up. It is detected as abnormal pressure roller heat up. 3. When the temperature of the heat roller does not reach does not reach 170°C within 140 seconds after the temperature of pressure roller reaches 80°C after warm-boots, it detects as abnormal heat roller temperature up. 4. When the temperature of the pressure roller does not reach 130°C within 70 seconds after the temperature of the heat roller becomes more than 170°C AND when the temperature of the pressure roller does not reach 150°C within 140 seconds, it detects as the abnormal pressure roller temperature up. 5. During printing or stand-by state, when the temperature of the heat roller goes below 70°C, it detects as abnormal heat roller low temperature. Pressure roller temperature is detected as abnormal pressure roller low temperature. 6. When the temperature of the heat roller goes above 210°C during the temperature control, it detects as abnormal heat roller high temperature. Pressure roller is detected as abnormal pressure roller high temperature. 7. For heat roller, the hard shuts down at 220°C and the thermostat shuts down at 210°C. Pressure roller hard shuts down at 205°C and thermostat shuts down at 150°C.
Remedy: 1 Check the connection between the fusing unit and connector. - Remove the fusing unit and install it again. 2 Does heater lamp 1 (H1) light on when turning the printer on? No Replace the fusing unit. 3 Does heater lamp 2 (H2) light on when turning the printer on? No Replace the fusing unit. Others Replace PU1 (power board). Replace PWB-A.
Code: 6033
Description: Transparency detection sensor error
Causes:
Remedy:
Code: 6034
Description: Multiple manual feeder pusher error
Causes: 1. MPT push-up tray position is detected while loading paper from the manual tray. 2. If the output of the manual tray upper position sensor (PC15) does not change even after the specified amount of time passed after the manual tray paper load solenoid (SL8) becomes ON, it is detected that the MPT push-up plate is abnormal.
Remedy: Does the manual tray push paper to the paper load roller? No Arrange paper on the manual tray. 2 Does the manual tray paper load roller one-way clutch have the claws? No Replace the one-way clutch gear. Yes Replace the manual tray paper load solenoid. Others Replace PWB-A.
