C2211,2212,2213 codes intermittently

[laserman06]

I would pull out the drum carriage and clean the connector on the back of the machine and drum carriage. I have seen many codes caused be that. Also, you might have a bad set of drums. Did this start after replacing the drums? If so I would swap them out.

i am getting these codes at random (drum speed). customer is running medium weight paper. Knowledge base recomends adjust drum speeds which I have done. I also re-powdered all drums which allowed about 2k clicks before coding again. any ideas would be greatly appreciated.
