ABSTRACT:
An imaging apparatus transfers toned images to sheets from a photoconductor surface and comprises: a movable photoconductor surface; a transfer roller positioned between support struts; a pressure roller positioned between support struts; a first spring system for biasing the transfer roller against the pressure roller; a second spring system connected to the transfer roller support struts; and a movable actuation mechanism coupled to the pressure roller support struts. The movable actuation system is engageable with the second spring system and first biases the transfer roller against the movable photoconductive surface. Additional movement of the actuation system enables the first spring system to remove the transfer roller from contact with the moveable photoconductor surface and to move the pressure roller from contact with the transfer roller, such movements out of contact occurring in sequence.
