Check continuity between J48 <=> P483. Go to Step 5. Replace the FAN/PHD/MOT Harness. 6 Check the fan rotation signal. Print one sheet. Is there +3.3 V across P/J48-A12 <=> P/J48-A13? Replace the Engine Control Board. Replace the Fuser Fan.
Code: 51
Description: Rear Fan Failure The Rear Fan rotation signal indicates the fan is no longer operational.
Remedy: 1 Check the Rear Fan for damage. Remove the Rear Cover. Is the fan damaged? Replace the Rear Fan. Go to Step 2. 2 Check the Rear Fan connection. Is P/J166 connected to the harness? Go to Step 3. Connect the Fan. 3 Check orientation of the Rear Fan. Does the Fan’s label face inwards? Go to Step 4. Correct the installation. 4 Test the Rear Fan. Run the Service Diagnostics Rear Fan test. Does the fan operate? Go to Step 6. Go to Step 5. 5 Check for +24 V to the fan. Disconnect P/J166. Is there +24 V across P166-1 <=> P166-3? Replace the Rear Fan. Replace the LVPS. 6 Check the fan rotation signal to the LVPS. Print one sheet. Is there +3.3 V between P/J166-1 <=> P/J166-3? Replace the Fuser Fan. Go to Step 7. 7 Check the rotation signal from the LVPS. Print one sheet. Is there +3.3 V between P/J165-15 <=> P/J165-3? Replace the LVPS. Go to Step 8. 8 Check the fan rotation signal at the Engine Control Board. Print one sheet. Is there +3.3 V between P/J61-4 <=> P/J61-16? Replace the LV Harness Replace the Engine Control Board.
Code: 52
Description: Fan Failure One of the two fans has failed resulting in a fatal error.
Remedy: 1 Check the fans for damage or debris: • Fuser Fan, PL1.1.19 • Rear Fan, PL5.3.31 Is either fan damaged? Replace the defective fan. Go to Step 3. 2 Replace the defective fan. Does the error persist? Go to Step 3 Complete 3 Test the fans. Run the Service Diagnostics fan tests to isolate the defective fan. Did one of the fans fail? Go to the troubleshooting procedure for the specific fan. If both fans pass, replace the Engine Control Board.
Code: 70, 71, 74
Description: Engine Firmware Failure The Engine Control Board detected a firmware error. Code 70: Fuser Temperature Control Failure Code 71: Long Cleaning Count Error Code 74: ASIC Error
Causes: • Engine Control Board, PL9.1.16
Remedy: 1 Does the error persist after the printer power is cycled? Replace the Engine Control Board. Complete
Code: 72
Description: Engine Firmware Failure The Engine Control Board detected a firmware error.
Causes: • Engine Control Board, Pl9.1.16 • EEPROM Board, PL9.1.12
Remedy: 1 Cycle printer power. Does the error persist? Go to Step 2. Complete 2 Is P/J144 on the EEPROM Board properly seated and defect free? Go to Step 3. Reseat P/J144 or replace the EEPROM Board. 3 Turn printer power off and then back on. Does the error persist? Replace the Engine Control Board. Complete
Code: 76
Description: Fuser Firmware Failure A failure was detected in the Fuser Firmware.
Remedy: 1 Check the Fuser for damage. Is the Fuser damaged? Replace the Fuser. Go to Step 2. 2 Check the Fuser connection for damage. Any broken or bent pins? Repair or replace the parts. Go to Step 3. 3 Replace the Fuser. Does the error persist? Go to Step 4. Complete 4 Check all pins on the FSR/ADC Harness PL5.2.28 for continuity. 1. Disconnect P/J36 and P/J361. 2. Check continuity between J36 <=> J361. Replace the Engine Control Board. Replace the FSR/ ADC Harness.
Code: 77
