Workcentre 7120 / System Error 092-315 on main display

I am getting a system error 092-315 on the main display on startup. Which indicates a ATC Fail (K) Black.

The error codes list states the following 092-315, 092-660, 092-668.

Upon inspection of the drum unit I found the (K) Black toner exit hole packed to the brim with toner
and piling up on top of the back of the drum. I looked at the other drum units (M,C,Y) and found no excess toner.

After vacuuming and cleaning the (K) Black drum unit area as bets as possible, and resetting NVRAM
752-368 (was at 1 reset to zero) 752-372 (was at 3 reset to zero).
Turned machine off (Top Power Button first then inside cover button next) Machine upon starting up printed several blank pages, then there was a metal clink sound and the 092-315 system error redisplayed itself on main screen.

I have determined that one of the following is at fault:
Main Drive Assembly – 007K16710
Dispense Motor -127K61161
Developer Clutch – 121K46371
Drum Drive Motor – 127K61161
