Image forming apparatus with a drive mechanism which uses an electromotive force of a motor to drive another motor

摘要

An image forming apparatus having a first motor for rotating a roller for transporting recording paper includes a second motor supplied with electric power from the same power line as the first motor, a driver circuit connected to the power line and generating driving electric power based on electric power from the power line to feed the driving electric power to the second motor, and a controller controlling, on detecting a jam of the recording paper and an open state of a cabinet cover, the driver circuit such that driving electric power is supplied from the power line to the second motor.

主权项

1. An image forming apparatus comprising:
a first motor for rotating a roller for transporting recording paper; a second motor for generating a rotating force for rotating a roller, different from the roller rotated by the first motor, for adjusting a fusing pressure of a fusing roller, the second motor being supplied with electric power from a same power line as the first motor; a driver circuit connected to the power line, the driver circuit generating driving electric power based on electric power from the power line to supply the driving electric power to the second motor; and a controller for controlling, on detecting a jam of the recording paper and an open state of a cabinet cover, the driver circuit such that driving electric power is supplied from the power line to the second motor.
