MPC6003 This code was intermittent for a while, but some how we got through it but re setting the bottle, not this time,we dis assembled the back and took off the toner motors, and the ID chips were all covered in toner as well as the chips on the bottles, the cleaning of these ID rf chips was the solution. Its not that the chips are bad, in many cases you may think the toner bottle chips are bad when its actually the ID rf chip in the back, so if your ever in the back go ahead and save yourself some anguish and clean these while your in there.
that is my FYI post of the day
