Transfix roller load controlled by motor current
摘要:
A printing device includes an image receptor adapted to have formed thereon an inked image layer, a transfer roller, and a transfer roller biasing system. The biasing system is structured to displace the transfer roller toward the image receptor upon actuation of a motor, exerting a backing pressure.
