To reduce toner consumption, if the developing unit is installed, the developing bias, the main
charger, and the grid are also outputted.
In this case, laser discharge is required when stopping the motor, the polygon motor is also operated
at the same time. Check for installation of the developing unit. If it is not installed, the high voltage
above is not outputted and only the motor is rotated.
