Abstract: An ink supply station for use with a first ink supply and a second ink supply includes a first module and a second module releasably coupled to the first module. The first module includes a first chassis and a first movable member supported by the chassis, wherein movement of the member causes flow of ink from the first ink supply. The second module includes a second chassis and a second movable member supported by the second chassis. Movement of the second member causes flow of ink from the second ink supply.

Abstract: The present invention is a replaceable ink container for use in an off-axis printing system. The printing system is responsive to electrical signals from the replaceable ink container for controlling printer parameters. The ink container has a leading edge and a trailing edge relative to the direction of insertion into the printing system. The replaceable ink container includes a plurality of electrical contacts disposed on the leading edge toward a first side. The plurality of electrical contacts are configured for engaging corresponding electrical printer contacts associated with the printing system. Also included is a fluid outlet disposed on the leading edge toward a second side opposite the first side and spaced from the plurality of electrical contacts. The fluid outlet is in fluid communication with the replaceable ink container. The fluid outlet is configured for engaging a fluid inlet associated with the printing system.

Abstract: The present invention is a replaceable marking media container for use in an off-axis printing system. The printing system includes a printer portion responsive to electrical signals from the replaceable ink container for controlling printer parameters. The replaceable marking media container includes a plurality of electrical contacts with each of the plurality of electrical contacts electrically connected with a memory element. The memory element contains information for controlling printing system parameters. Included in the replaceable ink container a housing having an outer surface facing outwardly and an inner surface. The inner surface defines a cavity within the housing. The plurality of electrical contacts are attached within the cavity, so disposed and arranged, to engage corresponding electrical contacts associated with the printing system.

Abstract: A module for a printing composition delivery system of a printing device that is a separable unit from the printing composition delivery system is disclosed. An embodiment of the module includes a printing composition supply station connector, a printing member connector, and a flexible conduit. The printing composition supply station connector is releasably attached to a printing composition supply station of the printing composition delivery system and has a coupler fluidly connectable to a printing composition supply of the printing composition supply station. The printing member connector is releasably attached to the printing device and has a coupler fluidly connectable to the printing member. The flexible conduit includes a first end fluidly connected to the coupler of the printing composition supply station connector and a second end fluidly connected to the coupler of the printing member connector to supply printing composition from the printing composition supply to the printing member.

Abstract: An amorphous silicon electrographic writing head assembly which reduces the voltage drift in the high voltage driving transistor. The writing head including a substrate having a first surface and a second surface, the first surface having thin film elements fabricated thereon, the first surface having a first region, a second region, and a third region, the first region including an array of writing electrodes, the second region including an array of high voltage transistors, and the third region including interconnecting circuitry for connecting the thin film elements to a connector. The head also includes a first cover glass fixed to the first surface of the array covering the first region and a second cover glass fixed to the first surface of the array covering the third region.

Abstract: Paper drive apparatus for multi-ply unglued paper wherein a centrally disposed pin wheel member is rotatable in contact with a backup member the latter having a central groove or slot into which the pins of the pin wheel member are rotatably receivable. Unglued, multi-ply paper is fed into the nip between the pin wheel member and the bifurcated backup roller across a demountable, flexible paper guide, the latter ensuring the proper angle of entry of the unglued paper with respect to the nip between the pin wheel and backup roller.
