Abstract: Ein System und Verfahren drucken auf einer durchgehenden Bahn von Bildgebungsmaterial in einer Druckmaschine. Ein oder mehrere Tintenstrahl-Druckköpfe scheiden Tinte auf die durchgehende Bahn von Bildgebungsmaterial ab, das von Walzen auf einem Transportweg getragen wird. Eine Luftkissenvorrichtung ist zwischen den Walzen angeordnet, um die Flachheit der transportierten Bahn während des Druckens sicherzustellen. Eine unerwünschte dynamische Bewegung der Bahn zu oder von den Druckköpfen, die sich aus Flattern, Muldenbildung oder Oberleitungsdurchhang der Bahn ergibt, wird reduziert, um einen Tropfenplatzierungsfehler sowohl in Querspur- als auch in Prozessrichtung zu minimieren.

Abstract: A belt drive module and a corresponding method includes or employs a belt (10) that moves along a path, at least one support roller (12) or other structure that supports the belt as it moves along the path, a drive roller (11) that effects movement of the belt along the path, a tension roller (74) that applies a tension force to the belt in order to maintain engagement of the belt with the drive and/or support rollers, at least one processing station (e.g., an image processing station) disposed along the path that performs a process relative to a predetermined position of the belt, and a torque assist drive that applies a torque assist force (Td) at a location between the drive roller and the tension roller. Torque assist may be provided by a current limited DC motor or by a constant torque friction clutch applied to a roller (66), e.g., a stripper roller of an electrophotographic imaging system. Advantageously, the torque assist force (Td) facilitates accurate positioning of the belt (e.g., latent image registrations in a color imaging process employing multiple imaging processing stations) by reducing slippage between the drive roller and the belt that may be encountered due to belt wear, toner contamination and/or other debris.

Abstract: A single pass, multi-color electrophotographic printing machine architecture uses a vertically oriented photoconductive belt. Transfer of th e toner powder images occur at the lowermost portion of the photoconductive belt. The photoconductive belt is elliptically shaped, having a major and a minor axis. N image recording stations are positioned adjacent an exterior surface of the photoconductive belt on one side of the major axis thereof. N -1 image recording stations are positioned adjacent the exterior surface of the photoconductive belt on the other side of the major axis thereof. The image recording stations record electrostatic latent images on the photoconductive belt. This architecture optimizes image registration while minimizing the overall height of the printing machine.

Abstract: A printing system facilitates the printing of articles of manufacture. The system includes an array of printheads, a support member positioned to be parallel to a plane formed by the array of printheads, a member movably mounted to the support member, an actuator operatively connected to the movably mounted member, an object holder configured to mount to the movably mounted member, and a controller operatively connected to the plurality of printheads and the actuator. The controller is configured to operate the actuator to move the object holder past the array of printheads and to operate the plurality of printheads to eject marking material onto objects held by the object holder as the object holder passes the array of printheads. The support member and printhead array are oriented vertically to enable the printing system to be installed in a vertical cabinet that provides a small footprint in a non- production environment.

Abstract: A method for delivering molten ink to a printing mechanism alternates between a first and second reservoir receiving molten ink from a receiving ink reservoir while providing ink from the other of the first and second reservoirs to a printing mechanism. The alternation of the two reservoirs is achieved with coordinated operation of two actuators operatively connected to two seal members.
