I have a MPC2500 with an ongoing issue where the machine when used in colour mode after say 50 copies it displays the message out of toner. If you switch the machine off and on again it displays the message loading toner please wait!! It then consumes almost an entire bottle of toner and wrecks the developer.
It is always the cyan or magenta units that have this problem. To date we have replaced the toner end sensors, the Controller board, the IOB PCB, the RFID PCB, the development units and drums, the ID sensor and the ribbon harness from the PSU to the controller. All firmware is up to date and the machine is running genuine toner.
Apart from hitting the thing with a bloody big hammer has anyone got any ideas or may have come across this before??
