Hi,
If the machine is still trying to add toner after the toner cartridge has been replaced & the developer is new then I would look at the toner supply motor for that particular colour. Also check for a blockage within the small tube between the toner cartridge & the developer unit. You could try swapping the toner supply motor with one of the other colour motors as they are all identical. If the fault switches to another colour then the motor is at fault.
You can also check the operation of the toner motor in simulation 10.
Hope this helps.
Dave.

you change the developer or drum unit

Replenish toner unit is the unit that is secured with two screws and comes to the right and these are unscrewed. The presence of this unit is signaled by a sensor positioned under the top cover. Check that sensor for proper functionality in Service Mode.
