International Classification:

G03G 15/01

US Classification:

399302

Abstract:

The present application is directed to second transfer areas and methods of transfer toner images from an intermediate member to a media sheet. The second transfer area comprises a second transfer nip formed between a second transfer roller and a back-up roller. The media path moves through this nip with the toner images on the intermediate member being transferred to the media sheets. The amount of force applied by the second transfer roller affects the transferability of the toner images to the media sheet. Further, the intermediate member may contact the second transfer roller at soft nip and hard nip locations. The lengths of these nips may also affect the transferability of the toner images.

Abstract:

The present application is directed to cleaner units and methods for removing waste toner from a transfer member within an image forming device. The device may include a blade that is positioned against the transfer member to remove the waste toner. The blade directs the waste toner into a cleaner house where the waste toner is removed. The cleaner unit is positioned within the image forming device to prevent contact with the media sheets moving along the media path. The cleaner unit may also be positioned to utilize existing elements to facilitate the removal of the waste toner from the transfer member.

International Classification:

G03G 21/16

Abstract:

A replaceable unit for an image forming device having features for aligning the replaceable unit when installed in the image forming device and to ensure alignment between the replaceable unit and a detachable unit attachable to the replaceable unit. End walls support a photoconductive drum and have a first bullet nose, second bullet nose and stop arm used for alignment of the replaceable unit in a frame of the image forming device. Support members are on a top surface of the bottom plate with a top planar surface of one of the support members forming a rotational stop and a datum surface for the detachable unit when attached. A mounting channel in one end wall provides a second datum surface for the detachable unit and a mounting channel in the other provides a deskewing plug to adjust axial alignment between the photoconductive drum and a roll in the detachable unit.

International Classification:

G03G 21/18

Abstract:

An imaging unit for an electrophotographic image forming device having positional control features for aligning the imaging unit in a supporting frame in the image forming device. The positional control features include on each end wall, first and second bullet noses and a stop arm positioned between the two bullet noses. The first and second bullet noses engage support or datum surfaces provided in corresponding openings in the frame. The stop arm receives a biasing force that rotates the imaging unit into its final operating position. A latching assembly is provided on one end wall to prevent the imaging unit from ejecting from the frame.
