Display: Laser motor failure CODE (0300) Turn power off, on Laser unit failure CODE (0310) Turn power off, on
Description: 0300 Laser Motor Failure and 0310 Laser Unit Failure • The Polygon Motor does not rotate evenly even after the lapse of a given period of time after it has been started. • The motor lock signal remains HIGH for a given period of consecutive time while the Polygon Motor is being rotated. • The SOS signal is not detected within a given period of time after the output of the laser has been started.
Causes: • Laser Unit, PL4.0.13 • Engine Control Board, PL13.0.20 • Power Supply, PL13.0.17
Remedy: 1 Check the Engine Control Board connectors P/J18 and P/J19. Are the connectors seated properly? Go to step 2. Reseat the connectors. If the problem persists, go to step 2. 2 On the Engine Control Board, check: • P/J19-1 for +24V • P/J18-10 and -11 for +5V Are the voltages present? Go to step 4. Go to step 3. 3 On the Engine Control Board, check P/J2-2 for +5 V. Check P/J2-1, -5, and -7 for +24V. Are the voltages present? Go to step 4. Replace the Power Supply. If the problem persists, go to step 4. 4 Replace the Laser Unit. Does the problem persist? Go to step 3. Complete. 5 Replace the Engine Control Board. Complete.
Code: 0500, 0503
Display: Fuser failure CODE (0500) Turn power off, on Thermistor failure CODE (0503) Turn power off, on
Description: 0500 Fuser Failure and 0503 Thermistor Failure The thermistor does not detect the specified temperature and the warm-up cycle is not completed even after the lapse of a given period of time.
Causes: • Fuser, PL4.0.13 • Engine Control Board, PL13.0.20 • Power Supply, PL13.0.17
Remedy: 1 Check that the Fuser is installed correctly and reseat it. Does the problem persist? Go to step 2 Complete. 2 Change the Fuser, and then turn the printer on, open the top cover, and press the following keys in this order: 2 > 6 > 2 > 3 > 7. Turn the printer off and then back on. Does the problem persist? Go to step 3. Complete. 3 Replace the Engine Control Board. Does the problem persist? Go to step 4. Complete. 4 Replace the Power Supply. Complete.
