Description: Transfer belt rotation failure
• The belt positioning sensor does not detect the transfer belt position detection hole a second time even after the lapse of a predetermined period of time after it has detected one while the transfer belt is rotated.
Remedy: 1 Check the PRCB connector for proper connection and correct as necessary. 2 PS6 sensor check. 3 Change imaging cartridge. 4 Change PRCB.
Code: 0094
Description: 2nd image transfer pressure / retraction failure
• The 2nd image transfer retraction position sensor is not activated (retracted position) within a given period of time after the retraction sequence of the 2nd transfer roller has been started. • The 2nd image transfer retraction position sensor is not deactivated (pressed position) within a given period of time after the pressure sequence of the 2nd transfer roller has been started.
Remedy: 1 Check the M1 connector for proper connection and correct as necessary. 2 Check the SD4 connector for proper connection and correct as necessary. 3 Check M1 for proper drive coupling and correct as necessary. 4 Check SD4 for proper drive coupling and correct as necessary. 5 Check the PRCB connector for proper connection and correct as necessary. 6 PS3 sensor check PRCB PJ12-3 (ON) C-2. 7 SD4 operation check PRCB PJ10-6 (REM) C-9. 8 M1 operation check PRCB PJ8-1 to 6 C-2. 9 Change M1. 10 Change SD4. 11 Change PRCB.
Code: 0300
Description: Polygon motor malfunction
• 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.
Remedy: 1 Check the cable and connector for proper connection and correct as necessary. 2 Change PH unit. 3 Change PRCB.
Code: 0310
Description: Laser malfunction
• The SOS signal is not detected within a given period of time after the output of the laser has been started.
Remedy: 1 Check the cable and connector for proper connection and correct as necessary. 2 Change PH unit. 3 Change PRCB.
Code: 0500
Description: Fuser warm-up failure
• The thermistor /1 does not detect the specified temperature and the warm-up cycle is not completed even after the lapse of a given period of time after the cycle has been started.
Remedy: 1 Change fuser unit. 2 1. Main switch is turned ON. 2. Open the top cover. 3. Press the following ten keys in this order 2-6-2-3-7. 4. Main switch is turned OFF/ON. 3 Change PRCB. 4 Change DCPU.
Code: 0502
Description: Thermistor open-circuit failure
• The temperature detected by the thermistor does not reach a predetermined level even after the lapse of a given period time after the warm-up cycle has been started.
Remedy: 1 Check the fuser unit for correct installation (whether it is secured in position). 2 Check the fuser unit, DCPU, and PRCB for proper connection and correct as necessary. 3 Change fuser unit. 4 Change PRCB. 5 Change DCPU.
