ABSTRACT:
A laser printer paper handling system employing separately controllable traction rollers having a registration roller and a fuser pressure roller which are separable from their associated pressure roller and fuser roller respectively, to allow separate engagement of the print paper during a print cycle. The registration roller engages its associated pressure roller and frictionally feeds the paper past a photoconductive drum. As the leading edge of the paper approaches, the fuser roller is engaged by the fuser pressure roller and the registration roller is disengaged causing the paper to be frictionally fed exclusively by the fuser roller. Operation of the rocker arm supporting the registration roller and the carrier bracket for the fuser pressure roller, as well as a paper platen which carries a standard corona transfer unit for activating the photoconducting drum, through a multi-surface cam provides position control for the system elements.
