My customer call to complain that he changed the black toner cartridge and something came off. When i get there the copier is a mess inside the carraige and the transfer belt assembly. Found that the white plastic cover inside the toner receptor assembly (black) this piece moves towards the back of the machine when you pop a new cartridge in , was missing so i put it on and mowed back and fourth so it settled in place. I vacumed the mess and cleaned the sensor and transfer belt assembly and reassembled everything. After poering the machine back up the adding toner cycle kept going and going, so that a toner dump condition returned. I think maybe the developer sensor maybe shot has any one had this trouble ?
