Description: 1st transfer pressure / retraction failure • The 1st transfer pressure sensor is not activated (retracted position) within a given period of time after the 1st transfer pressure solenoid has turned ON. • The 1st transfer pressure sensor is not deactivated (pressed position) within a given period of time after the 1st transfer pressure solenoid has turned ON.
Causes: • 1st transfer pressure sensor (PS17) • Transport motor (M2) • 1st transfer pressure solenoid (SD1) • Printer control board (PRCB)
Remedy: 1 Check the connector between M2-PRCB CN11 for proper connection and correct as necessary. 2 Check the M2 connector for proper drive coupling and correct as necessary. 3 Check the connector between PS17-PRCB CN9 for proper connection and correct as necessary. 4 Check the connector between SD1-relay CN25-PRCB CN7 for proper connection and correct as necessary. 5 PS17 sensor check PRCB CN9-6 (ON) 12-J 6 SD1 operation check PRCB CN7-4 (REM) 13-D 7 M2 operation check PRCB CN11-10 to 13 13-B to C 8 Replace PS17. 9 Replace SD1. 10 Replace M2. 11 Replace PRCB.
Code: 0101
Description: Power malfunction When opening or closing the door and cover, a paper jam occurs, or the power is not supplied to the printer control board even after a specified period of time passed.
Causes: • Front door sensor (PS10) • Right door sensor (PS11) • Front door switch (SW2) • Right door switch (SW3) • DC power supply (DCPU) • Printer control board (PRCB) • MFP board (MFPB) • PH unit
Remedy: 1 Check the connector between PS10-PRCB CN15 for proper connection and correct as necessary. 2 Check the connector between PS11-PRCB CN15 for proper connection and correct as necessary. 3 Check the connector between PRCB CN5-MFPB CN16 for proper connection and correct as necessary. 4 Check the connector between DCPU CN4-relay CN90- SW2-SW3-relay CN90-PRCB CN1 for proper connection and correct as necessary. 5 Check the connector between DCPU CN3-PRCB CN3 for proper connection and correct as necessary. 6 Check the connector between PRCB CN18-relay CN63-PH unit for proper connection and correct as necessary. 7 PS10 sensor check PRCB CN15-3 (ON) 15-H 8 PS11 sensor check PRCB CN15-6 (ON) 15-H 9 Replace PRCB. 10 Replace DCPU. 11 Replace the PH unit. 12 Replace MFPB.
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.
Causes: • PH unit • Printer control board (PRCB)
Remedy: 1 Check the connector between PH unit-relay CN63- PRCB CN18 for proper connection and correct as necessary. 2 Replace the PH unit. 3 Replace 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.
Causes: • PH unit • Printer control board (PRCB) • MFP board (MFPB)
Remedy: 1 Check the connector between PH unit-relay CN63- PRCB CN18 for proper connection and correct as necessary. 2 Check the connector between PH unit-MFPB CN15 for proper connection and correct as necessary. 3 Replace the PH unit. 4 Replace PRCB.
Code: 0315
Description: PH board communication error • Mismatching of data being written and read occurs continuously for certain times during communication with the PH board. • The EEPROM of the PH board is not yet initialized.
Causes: • Front door sensor (PS10) • Right door sensor (PS11) • Front door switch (SW2) • Right door switch (SW3) • DC power supply (DCPU) • Printer control board (PRCB) • MFP board (MFPB) • PH unit
Remedy: 1 Check the connector between PRCB CN18-relay CN63-PH unit for proper connection and correct as necessary. 2 Replace the PH unit. 3 Replace PRCB.
Code: 0500
Description: Heating roller 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.
Causes: • Fusing unit • Printer control board (PRCB) • DC power supply (DCPU)
Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the connector between fusing unit-PRCB CN9 for proper connection and correct as necessary. 3 Check the connector between fusing unit-DCPU CN2 for proper connection and correct as necessary. 4 Replace the fusing unit. 5 Replace PRCB. 6 Replace DCPU.
