What causes a OO94 error code. Something to do with image transfer belt? Thanks Buddy

When I get this error with a grinding noise I replace the Transport assembly. New part number is #A12R70533.

There are a couple of very good threads on this topic. Try searching 0094 (zero zero nine four) not OO94 (Oh Oh nine four). =^..^=

Yes many times. Reassemble it, you could find a broken gear stud in there...

Check the timing on the gears for the shutter. It the roller is all the way up the shutter should be completely closed.
There is a hole in the gear to position it. Never checked the manual to align it.
This would not trigger the code but the machine would not be able to calibrate properly or transfer toner.

The retraction solenoid has a tiny foam sound damping pad, this over time gets sticky & causes the solenoid to not return, simply remove this sticky foam pad.

Possibility of broken stud on the lowest level gear like Allan is saying or just pul it apart and re-assemble. When re-assembling there is arrow on two gears and each of the gears has its own position against the frame where you will find a little cut in. Once bothe aligned then put the small gear in between them two. Then keep it in place and put the cover with wires inside (crap design) and 2 screws in.

If I can suggest, check the plastic bushings on the silver reg.roller both sides. They tend to go eliptical. Slowing reg feed down and ocasionally skew.
