Abstract: An ink-jet printer with a maintenance mechanism uses a single-cam to clean and maintain a recording head. The cam is driven by a paper-feed motor in the forward direction during the maintenance operations. When the recording head is disposed in a maintenance area, the driving force of the paper-feed motor is transferred to the cam via a coupler. In one revolution of the cam, a suction cap, a suction pump, and a wiper are driven at a predetermined timing to clean the recording head. The paper-feed motor is also used to drive the platen roller during the recording operation. Because a common motor is used to drive the platen roller and the cam, and because a single cam completes the maintenance operations in one revolution, the structure and its control are simplified.

Abstract: A fiber tracking management system controls fibers clinging to an inkjet printhead in an inkjet printing mechanism, to stop these fibers from trailing across freshly printed wet ink and leaving unsightly fiber tracks. The system includes a sled which supports a fiber crushing member that contacts the printhead when the sled is in the servicing position and crushes fibers dangling from the printhead against the printhead. The printhead carriage has a datum which extends over the printzone and collects fibers from a wiper following printhead wiping. The system also has a fiber remover which removes fibers deposited along the exterior surface of the datum. The fiber remover may be a clutch actuator or other mechanism which plucks the fibers off the carriage, or a compressible pad which smashes the fibers and scrubs ink residue from the datum. A method of controlling fibers clinging to an inkjet printhead is also provided.

Abstract: The ink jet recording apparatus of this invention comprises a means 67 for heating a record material to a predetermined temperature range at the position of recording, a recording head 41 for ejecting ink 46 from an ink ejection orifice 49 toward the record material to perform recording, the ink containing a substance having thickening properties when undergoing heat, and/or a substance having a cloud point for the heat; a means 69 for measuring the duration for which the recording head resides at the position of recording; and means for controlling the duration of residence in accordance with the properties of the ink to prevent the ejection function being impaired owing to the heating of the surroundings of the ink ejection orifice. This invention can provide an ink jet recording method which determines a rise in the temperature in the surroundings of the ink ejection orifice on the basis of the duration of residence of the recording head at the position of recording for the purpose of recording, and which performs control to suppress the temperature rise before the ejection function is interrupted.

Abstract: A liquid ejecting apparatus includes: a head member having a nozzle and a liquid-ejecting unit; a main controlling part that drives the liquid-ejecting unit based on ejecting data; a capping member relatively movable between a position away from the head member and a position in contact with the head member; a suction way communicated with an inside of the capping member; and a built-in slide-rotator type of positive displacement pump provided in the suction way. A state-quantity recognizing part recognizes a state quantity related to a dry state in an inside of the positive displacement pump. A judging part judges whether the inside of the positive displacement pump is dry, by comparing the state quantity with a standard state quantity. A preliminary-operation carrying-out part carries out a preliminary operation for wetting the inside of the positive displacement pump, when the inside of the positive displacement pump is dry.

Abstract: A printer maintenance apparatus, includes: a mounting base movable forward and backward between a maintenance position and a retraction position; a wiping mechanism mounted on the mounting base and including a wiper base and a wiper; and a capping mechanism mounted on the mounting base including a cap base and a cap. The cap base moves toward the nozzle surface to move the cap to cover the nozzle surface when the mounting base is at the maintenance position. The cap base moves retractably from the nozzle surface when the mounting base moves from the maintenance position. The wiper base moves toward the nozzle surface to bring the wiper into contact with the nozzle surface when the mounting base is at the maintenance position. The wiper base keeps the wiper in contact with the nozzle surface while the mounting base moves backward from the maintenance position.

Abstract: An inkjet printhead squeegee is split on one side so that its wiping force on a printhead is highest on the front stroke and much lighter on the backstroke when the surface is dry. Alternatively, the split can be arranged so that the front stroke is light enough to leave the printhead wet, and then the backstroke is much firmer to completely squeegee the printhead dry. The result is high pressure strokes on a dry printhead are avoided.
