    摘要: An ink-jet apparatus is disclosed having a vacuum type print media transport subsystem for moving the print media through a printing zone. A transport belt is provided with an array of perforations such that vacuum flow is restricted. The perforations only pass vacuum induced airflow through the belt when over vacuum ported platen regions.

    摘要: The invented printer includes a carriage-actuated clutch and a motor-driven gear element. The clutch is selectively engageable with the element and causes the printer to perform different tasks when engaged. More specifically, the invented printer includes a motor-driven gear, a printhead and a printhead carriage, a clutch having a flexible portion, and a gripping surface on the flexible portion for engaging the motor-driven gear. To actuate the clutch, the carriage pushes against the clutch causing it to flex and engage the motor-driven gear. When engaged, rotating the gear a predetermined distance causes the clutch to rotate a predetermined distance, in turn causing the printer to perform a certain task. Continuing to rotate the clutch causes the printer to perform other tasks.The invented printer also includes a paper-feed mechanism for picking up and feeding a sheet of paper into the printer. This mechanism incudes a rotatable drive roller that moves paper through the printer, a spring-biased plate capable of pivoting around an axial pivot, biased to extend toward the drive roller and on which paper is tacked, a partition, having at least one opening, positioned between the roller and the plate for generally preventing the roller from contacting the media on the plate, and a pivot adjacent the roller for selectively allowing at least a part of the roller to extend through the opening in the partition to contact the top sheet of paper and feed it through the printer. The paper-feed mechanism is one task that may be triggered by the carriage-actuated clutch.

    摘要: A method and apparatus is disclosed for operating an ink jet print head 14 of the type having an air chamber 64 to which a stream of air is delivered and an ink chamber 32. A valve 48 interrupts the flow of air to the air chamber 64 from time to time, such as after each copy of a print is printed by the print head. This reduces the air pressure within the air chamber 64 and permits ink from ink chamber 32 to enter the air chamber 64 and replenish ink within the air chamber. The ink pressure is increased while the air pressure is reduced. This reduces the time required to replenish the ink. With the ink in the air chamber maintained at a consistent quantity and shape, the convergence of ink drops on printing medium is enhanced.

    摘要: Methogology and apparatus are described which employ an improved modular service station design wherein a printhead-servicing sled is selectively vertically driven to effect execution of servicing tasks. In keeping with its desired modularity, the sled is made readily removable using an improved clamp and sled arrangement. The sled is driven by a unique drive system such drive system being capable of effectively selectively stalling or locking instrumentality such as the sled in various positions defined along its path of vertical movement. To save time and space, both the printhead and the servicing mechanism such as the wipers and the caps are moved so as to place them in proper relative positions for execution of a task. Precise relative positions of the servicing mechanism and the printhead are achieved and maintained during the course of a servicing task such as printhead capping by employment of an improved printhead registration system which limits relative rotation between the printhead and the servicing mechanism.

    摘要: A sheet media realignment mechanism is described for use in, for example, a printer. Preferably, the mechanism includes a lever located in the sheet-feeding path adjacent and beneath a rotatable member that mounts a plurality of sheet-feeding rollers. At the beginning of a sheet-feeding cycle, the lever is urged from its extreme upstream pivotal orientation by a pivot-mounted strut into a downstream orientation in which a top sheet of the printer's infeed stack is fed by frictional forces into the feed zone. Upon release of the lever by the strut at a predefined pivotal orientation of the rotatable member, the lever is urged farther into an extreme downstream orientation by the sheet being advanced. After the sheet passes by, the lever is returned to its extreme upstream orientation in which it urges upstream and away from the printer's feed zone any sheets of the stack that inadvertently may have been dislodged and partly advanced downstream and toward the feed zone by frictional forces between the fed sheet and those beneath it. Thus, the lever realigns the sheets of the paper stack after each single-sheet feed into the printer or other sheet media-processing equipment to permit the addition of sheets to the top of the stack without pulling the stack away from the feed zone and to reduce the likelihood of undesirable multiple-sheet picks and feeds.
