Motors
The printer has four motors. The motors drive the components in the paper-feed and image-formation
systems.
The DC controller monitors the fuser motor and the drum motor to determine whether a motor has failed. It
noties the formatter when it encounters the following conditions:
●
Startup failure: the motor does not reach a specied speed within a specied time from when the motor
starts.
●
Rotational failure: the rotational speed of the motor is not in the specied range for a specied time
after the motor reaches a specied speed.
