摘要： A waste toner removal device for transporting toner from a photoconductive drum within an image-forming apparatus. The invention includes a waste toner reservoir having outer walls forming an interior chamber for housing toner removed from the photoconductive drum. An opening is positioned within the outer walls into the interior chamber forming an upper chamber section extending above the opening and a lower chamber section extending below the opening. An auger extends along the photoconductive drum and unobstructed into the opening of the waste toner reservoir. The auger includes helical blades extending outward for moving the toner from the photoconductive drum into the waste toner reservoir. A pumping cylinder having a generally cylindrical shape extends around the auger adjacent to the waste toner reservoir. The diameter of the pumping cylinder is approximately equal to the helical blades wherein rotation of the auger creates a pumping action for moving toner into the said upper and lower chamber sections.

摘要： A device within an image forming apparatus for positioning a doctor blade against a developer roller and preventing toner leakage. The device includes a developer housing for containing the developer roller and the doctor blade. A biasing member is positioned adjacent to the doctor blade for forcing the doctor blade against the developer roller for controlling the mass flow and charge level of the toner. The doctor blade is supported by retention stops on a front edge and a pair of supports on the back edge. Toner is prevented from leaking through the device by a flap seal positioned along the doctor blade back side and a seal positioned between each end of doctor blade end and developer housing. The invention provides for the doctor blade to be freely positioned between the retention stops, developer housing, and seals providing for the doctor blade to contact the developer roller in a consistent manner.

摘要： A developer reference system for a contact development process having machine frame mounted support rollers for the developer roll. Skew between the PC drum and the developer roll is reduced by referencing each to the same support structure. Rolling resistance of the developer roll support rollers is reduced by using thin diameter metal pins for mounting the support rollers.

摘要： A system and method reduces wear on an image-forming device. The image-forming device includes one or more toner cartridges, each having an associated PC drum and transport member to transport toner images or media. Each of the PC drums maintain contact with a surface of the transport member regardless of whether they are being used to form a toner image. A controller controls the rotation of the PC drums to rotate or not rotate while in contact with the surface of the transport member.

摘要： 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.
