An apparatus in which a sheet is advanced into registration with different color information developed on master sheets secured releasably on different drums. Each master sheet is secured to a gripper bar having outwardly extending pins. The pins in the master sheet gripper bars mount in holes in the drum and extend outwardly therefrom. A chain driven gripper bar advances the sheet into registration with successive master sheets. The sheet gripper bar is mounted pivotably and slidably on the chain. The sheet gripper bar has notches in the leading edge thereof to mesh with the pins extending from the master sheet gripper bar. This detachably couples the sheet and the master sheet to move in unison with one another. In this way, the sheet is placed in registration with the different color information developed on each master sheet. After the color information is transferred from the master sheet to the sheet, the sheet gripper is decoupled from the pins and advances with the chain to place the sheet in registration with the next successive master sheet.

Registration apparatus for a printing system

An apparatus which transports a sheet through a transfer station to transfer an image from an image receiving member thereto. A stationary member has at least a portion thereof positioned closely adjacent the image receiving member to define a transfer zone therebetween. A substantial portion of the sheet is vacuum tacked to the transfer member. The sheet is moved relative to the transfer member to advance through the transfer zone so that the image is transferred from the image receiving member to the sheet.

Sheet transport system

A modular developer and cleaner housing for use in an electrostatographic reproducing apparatus of the type wherein a recyclable imaging member completes two cycles for each copy produced, includes a development portion and a cleaning portion with the development portion including means for continuous development engagement with an imaging surface, and the cleaning portion including a cleaning blade for cleaning an imaging surface and including means for alternately positioning the cleaning blade into and out of cleaning engagement with the imaging surface. The cleaning portion further includes a used toner collection enclosure to collect used toner cleaned from the imaging surface by the cleaning blade which is separated from the development portion of the housing whereby toner cleaned from the imaging surface is collected separately from the developer.

Electrostatographic reproducing apparatus

A printed circuit card receptacle formed of one or more edge connectors having a pair of opposed, slotted card guides affixed thereto. The receptacle includes a mountable connector having a channel member at either end thereof for receiving the guide. Each card guide has a sleeve portion for slideably engaging the channel member and a releaseable locking means for holding the card guide affixed in place after full engagement of the sleeve with the channel member. The receptacle includes means for holding the printed circuit card in the connector.
