Abstract: A ghosting preventing development process cartridge detachably mountable into an electrostatographic reproduction machine is provided. The ghosting preventing development process cartridge includes a housing having walls defining a partially enclosed storage chamber for storing developer material, and a development opening into the storage chamber. The ghosting preventing development process cartridge also includes a donor roll, mounted rotatably outside the chamber and near the development opening, for receiving a layer of developer material from the storage chamber, and for donating portions of such developer material layer within a development nip to image areas of an image being developed thus leaving a spent developer layer on the donor roll downstream of the development nip. The ghosting preventing development process cartridge further includes a developer material disturbing (DMD) member mounted into moving contact with the donor roll, and downstream of the development nip, for disturbing the spent layer of developer material on the donor roll, thereby preventing ghosting effects occurring in subsequently developed toner images by eliminating any ghost effects of a previously developed toner image from the spent layer of developer material on the donor roll.

Abstract: A printing apparatus includes a guide member for directing sheets toward a transfer zone. The guide member defines a set of ribs which hold the sheets above the main surface of the guide member. Thus, any stray marking material which lands on the guide member is relatively unlikely to contact a sheet moving over the guide member.

Abstract translation: 打印装置包括用于将纸张朝向转印区域引导的引导构件。 引导构件限定了将片材保持在引导构件的主表面上方的一组肋。 因此，落在引导构件上的任何杂散标记材料相对不太可能接触在引导构件上移动的片材。
