Abstract: A cleaning member is pivotally fixed to a support member to clean ink-jet print heads that are positioned on a print-head receptor module. The cleaning member pivots from a cleaning position to an idle position and the print-head receptor module is pivotally fixed to a support member to allow the module to pivot from a printing position to a cleaning position. The pivotal supports are positioned such that, when the module and the cleaning member are each in their respective cleaning positions, the cleaning member is positioned to clean ink jets inserted into the receptors.

Abstract: A method and system for managing personal data of subscribers via a network are described. In one embodiment, personal data of a subscriber is captured in a personal data capture device. The personal data is transmitted from the personal data capture device to a network server. The personal data is then analyzed to generate feedback information. This feedback information is presented to the subscriber via the network.

Abstract: A method and system for transmitting data over a network are described. In one embodiment, the system comprises a cradle to transmit data to a network server and an electronic device coupled to the cradle. The electronic device includes a sensor to trigger a data connection between the electronic device and the cradle. The electronic device also includes a transmitter to download the data to the cradle.

Abstract: An improved toner applying apparatus is provided for developing an electrographic latent image formed on the charge retaining surface of a moving recording medium. The toner applicator includes a housing defining an internal reservoir and including a series of longitudinal, parallel toner applying recesses which are disposed for developmental engagement with a moving recording medium across its entire width. Each toner applying recess communicates with the reservoir. Internal baffles are provided across a toner inlet to the reservoir chamber to provide uniform fluid pressure throughout the reservoir. The parallel toner applying recesses provide a more even and constant flow of toner than is possible in prior art roller applicators and completely eliminate the problem of electrodeposition or plating up of toner particles on the applicator.

Abstract: A vacuum transport belt for use in a multipass, multicolor raster printer has a vacuum attach means for providing a strong hold down vacuum force in the direction of paper travel for complete registration of a recording material with respect to a writing head and toner system. The vacuum attach means comprises a thin metal strip bonded to a transport belt such that the surface of the strip is substantially flush with the surface of the belt. A strong hold down vacuum is conducted through channels underneath the bonded strip to a series of closely clustered apertures which form a vacuum contact region on the strip. The force of the vacuum applied at the contact region and the substantially flush contact between the surface of the strip and the transport belt tightly seals the entire surface of the recording material to the transport belt, thereby registering the recording material precisely to the transport belt in an invariant desired alignment with a writing head and toner system.

Abstract: A multipass, multicolor electrostatic plotter or printer has a continuous vacuum transport belt rotatable for substantially a complete revolution past a stationary writing head. The vacuum transport belt provides a vacuum to the entire contacting surface of a recording medium to stabilize and register the recording medium with a previously unattainable degree of invariance, thereby enabling information to be printed upon the recording medium simply by moving the transport belt with respect to a stationary electrostatic writing head disposed for contacting the recording medium across its entire width.

Abstract: An electrostatic color printer method using a single toning shoe for successively and sequentially applying color liquid developers to a color latent image overlay to a sheet disposed against a rotating drum. An electrostatic head scans the sheet in a helical pattern of abutting stripes and forms the latent image on the sheet. A toning shoe assembly follows the head and applies one of the color developers to the sheet. A drain selector foot, pivotable beneath the toning shoe, brings an appropriate developer recycling tube into communication with a drain in the toning shoe assembly for returning used developer to the correct supply tank. After scanning the sheet, the toning shoe is rinsed with a solvent at a cleaning station past the end of the drum. The toning shoe has a plurality of pressure responsive reed valves, each communicating with one of a plurality of channels in the shoe for selecting sequential color developers until the entire image is toned in repeated passes of the single toning shoe.
