Ok. It started out simple enough. Gray background on prints and copies. I found something sticky on the transfer belt. Each time it comes around it snags on the transfer cleaning blade. No sweat. So I put it all together and I get a surprise: C2351.
I've seen the bulletin, so I order and install first the cleaning motor K, second black drum unit, third engine PWB. It's got v. 8.00 firmware. I've turned the cleaning drive by hand- it turns quite easily, yet in sim U030 'Paper Feed' the motor can be stopped very easily and seems to me to turning too slowly, much slower than the adjoining motor of the same type.
Along the way I've found a sheared off cleaning auger in the black drum unit, and after the engine PWB a CF18A (must be firmware since a flash solved that). This machine is kicking my butt.
I thought about the main drive unit, but have not pursued it yet. It a major pain to change, and I'd like a logical reason to do so.
Does anybody have any ideas? =^..^=

but its either the cleaning motors or the developer motors gone bad. 2 of each in the back of the machine. i've replaced lots of these for that code.

black be carefull check connector cn-16 on the engine pcb...make sure power is supply there for that motor...90% of the time is the motor..good luck
