When you have a sensor failure, you need to replace the black ATC sensor and recalibrate it. Another reason for sensor failure is you are not getting toner moved down to mix with the developer...the toner tube/auger spring could be clogged up or not functioning.

Also if you changed the developer housing when you changed the developer, you need to change the value to the new sensor # that comes with the housing.

Do you have an error code?

Hi Zelwe Mwanza
show me error code pls

U2 is an engine EEPROM failure - you'll need to replace the main board to fix that, I'm afraid.

U6 is a low voltage psu failure. It may be that the power connector to the engine controller board became dislodged during the move. You can check the details in the manual which you can download here.

From the service manual:

Code 83: Engine NVRAM is corrupted or receiving wrong data from a CRUM.

1 Cycle power to the printer. Does the error still appear? If so, go to step 2.

2 Remove and reinstall the Imaging Unit and Fuser Assembly. Does the error recur
after the power has been turned off and then on? If so, go to step 3.

3 Replace the imaging unit. Does the error still occur? If so, go to step 4.

4 Replace the fuser assembly. Does the error still occur? If so, to to step 5

5 Replace the EEPROM board. Does the error still occur? If so, replace the Engine Control Board.

Hi mgordonO:
The problem is with the toner cartridge or the developer. One or both may be empty.

Hiya,

Can you be more specific regarding the Engine Logic Board Failure as in is it timing, rom/ram, micor pitch or NVRAM as code 80 is a failure code for
Engine Firmware Halt Failure .

POSSIBILITIES

Problem:
1st BTR Contact Failure or 1st BTR Retract Failure Message is displayed after replacing the Accumulator Belt Cause:
A Phaser 7700 Accumulator Belt was installed in a Phaser 7750. The Phaser 7700 Accumulator Belt does not have retractable 1st Bias Transfer Rollers; so these errors will be reported if one is installed in a Phaser 7750 printer. Solution: Fixed! Did not fix. Remove the Phaser 7700 Accumulator Belt and install a Phaser 7750 Accumulator Belt. TRY FIRST (Solutions without parts):
1. Check that all shipping restraits have been removed.



TROUBLESHOOTING TIPS AND HINTS:
1. Test the 1st BTR motor in diagnostics to verify proper operation. 2. Test the 1st BTR sensor in diagnostics, then run the 1st BTR motor test and recheck the 1st BTR sensor. Sensor state should alternate between L and H. The sensor is part of the accumulator belt.

PARTS:Parts are listed in the order of highest probability for repair.

REPAIR/INSPECT/PREVENT PROCEDURE:
1. Clean feed rollers, exit rollers and guides; replace if
necessary.
2. Clean feed rollers and exit rollers only when dust or
debris is visible.
3. Remove and clean all paper trays.
4. Clean the Laser Scanner Unit window.
5. Inspect the image density sensors; clean if necessary.
6. Inspect the accumulator belt home sensor; clean if
necessary.
7. Inspect the fuser assembly; clean if necessary.
8. Print the Error Log, diagnose and repair any problems as
indicated.
9. Print the Usage Profile, diagnose and repair any
problems as indicated.
10. Check version of all installed firmware; as
appropriate, install the latest version of firmware.
11. Check cleanliness of interior and exterior of printer,
including fans; if necessary, clean (dust or vacuum) these
areas.
Problem:
