Abstract: A fluid cartridge for a printing device includes a housing including a floor, a chamber defined in the housing and configured to store an ink therein, a capillary medium disposed in the housing and in operative communication with the chamber, and a wick disposed at least partially in an opening of the floor, the wick including a portion extending a predetermined distance into the housing such that the wick portion contacts the capillary medium. The fluid cartridge further includes an enriched pigment-confining member established inside the housing such that the confining member physically contacts the floor and surrounds at least a portion of a periphery of the wick. The confining member is configured to i) block enriched ink from the wick, and/or ii) dilute the enriched ink prior to flowing through the wick.

Abstract: A document handler 20 for presenting documents to the platen 23 of a copier 10 for copying with a vacuum belt platen transport system 32 having document transporting belts 35 movable under a substantially planar vacuum plenum backing and imaging background surface 33a overlying the platen, and a vacuum system 33 for applying a partial vacuum to a document sheet being transported by the movable belts over the platen; with a clamping and unclamping system for moving the vacuum plenum backing and imaging background surface 33a against the platen 23 to flatten the belts 35 and a document thereon against the platen for copying.

Abstract: A document handler 20 for presenting documents to the platen 23 of a copier 10 for copying with a vacuum belt platen transport system 23 having plural unapertured, thin, low-frictional, document transporting belts 35 with substantial exposed spaced 35a between the edges of the belts, the belts being movable under a substantially planar vacuum plenum backing and imaging background surface 33a overlying the platen, and a vacuum system 33 for applying a partial vacuum to a document sheet being transported by the movable belts; wherein the vacuum plenum surface 33a has multiple vacuum apertures 53 located under and overlaid by the edges of the belts 35, the belts extending in rows under the belt edges across the surface, but not extending into the exposed spaces between the belts. The belts are opaque and white and optically conceal the overlaid vacuum apertures 53.

Abstract: A bottom vacuum corrugation feeder includes a vacuum chamber with a bi-level support surface that support a plurality of apertured belts. The bi-level support surface has a series of raised members on a portion of its surface that corrugate the bottom sheet of a stack of sheets that are supported on a stacking tray. The stacking tray inclues raised members on its stack support surface that allow the venting of air from an air knife positioned in front of the sheet stack for separating the bottom sheet in the stack from the remainder of the stack. Recesses are included in the stack support surface of the stacking tray in order to reduce vacuum leak around the front edge of the sheet stack.
