  • Publication number: 20120301165
    Abstract: A metering skive for a dry electrophotographic (EP) printer is mounted on a retractable skive mount. The skive mount is spring-loaded to a mounting block, and a stop pin sets the distance between the skive mount and the mounting block. A movable spacer with a plurality of laterally-separated regions of respective, different thicknesses is mounted between the head of the stop pin and the mounting block. A retractor can be operated to pull the skive mount towards the mounting block so the spacer can be moved to select a desired spacing between the mounting block and the skive mount, and thus a desired gap between the metering skive and the toning member in the printer.

  • Publication number: 20120207509
    Abstract: An electrophotographic printer includes a rotatable photoreceptor adapted to receive dry toner and a rotatable toning member arranged with respect to the photoreceptor to supply toner thereto. A seal includes a complaint contact member and a non-contact member. The contact member is arranged in mechanical contact with the photoreceptor. The non-contact member is spaced apart from the surface of the toning member by a selected non-zero distance, the selected distance being greater than zero. This reduces dusting.
