Abstract: An apparatus for varying nip pressure in a media feedpath including a feed roller and a pressure roller defining a feed nip there between includes a rotatable cam having a preselected eccentric path when rotated, a first pivotable linkage pivotally engaging the rotatable cam, a second pivotable linkage, a biasing member operably interconnecting the first and second pivotal linkages for providing a biasing force on the pressure roller. The pressure roller is rotatably connected to the second linkage opposite the biasing member, wherein rotation of the cam varies the biasing force provided by the biasing member on the pressure roller.

Abstract: The present invention includes a damping device for a media feed mechanism for a peripheral device having a media feedpath having a feed shaft and a downstream exit shaft. In one form a damping hub is mounted on said exit shaft, a resilient biasing member extending between the damping hub and the feed shaft to create a damping force on the damping hub. In another embodiment damping is provided by a brake structure engaging said damping hub. In yet another embodiment, a brake structure is pivotably mounted.

Abstract: An imaging apparatus includes a printhead carrier system including a printhead carrier configured for movement along a scan path, a first sheet picking mechanism, a second sheet picking mechanism, and a selector device. The selector device is configured to select one of the first sheet picking mechanism and the second sheet picking mechanism for picking a sheet of print media based on a position of the printhead carrier.
