developer drive assembly for correct installation or, any sign of worn,
loose, or broken parts.

Toner sensor
The toner sensor cable is part of the front harness and part of
connector J15 on the system board. Check the voltage at J15-11. It
reads approxi5 V dc. If incorrect, replace the system board.
If correct, check the voltage at J15-12. It reads approxi5 V dc
with the system board removed from the printer. If incorrect, replace
the system board. If correct, replace the toner sensor assembly. A
bad ground connection between J15-13 on the system board and
pin 3 on the toner sensor results in a 929 service error.
