SOURCE: there is an error code
Abnormally high toner density detected Black TRC sensor-
1. Correct the TRC Connection on the underside of the imaging unit if faulty
2. Reinstall black image unit
3. Change image unit
4. Change PWB-M
5. Change PWB-MFP
you can try # 2 then run 20-30 sky shops (copies with lid up to make black copies) put a white piece of paper over lead edge section of copy glass so you are only making 1/2 black copies if you don't the copy may jam in the fuser due to excess toner. after running copies turn machine off for 10 secs to reset and power backon. if problem continues I would change the image unit.

This is a sign of wear if you can check the internal mechanics of the printer when it is running, you will see that there is a gear issue.
