    Often the 'plug' from the top of the previous toner bottle gets stuck and remains in the mouth of the toner hopper, blocking the toner flow

    Check that the gears on the development unit are not stripped. This is a common problem with PCU that have been rebuilt. When they get stripped, the mixer shafts do not turn and new toner is not mixed in.
