NOTE: This simulation must be executed without installing the
toner cartridge and the toner hopper.
If this simulation is executed with the toner cartridge and
the toner hopper installed, toner will be forcibly supplied to
the developing unit, resulting in over toner.
If this simulation is erroneously executed with the toner car-
tridge installed, the over toner state may be canceled by
making several background copies.
