摘要： A print drum for carrying sheets of media during printing, including a rotatable carrier drum generally defining an outer cylindrical boundary about a drum axis, and at least one media control member extending laterally substantially parallel to the carrier drum axis. The media control member is controllably movable between (1) a first position extending beyond the carrier drum boundary to define a lateral alignment barrier for a leading edge of a media sheet when adding the media sheet to the carrier drum, (2) a second position beneath the outer cylindrical boundary when printing on the added media sheet, and (3) a third position projecting outwardly of the outer cylindrical boundary to push the leading edge of the added sheet of media away from the outer cylindrical boundary.

摘要： Techniques for high accuracy media positioning in a swath printer. A high accuracy media positioning method includes mounting a computer-controlled printing element for movement along a swath axis for swath printing of an image on a print medium, moving the printing element along the swath axis and printing at least a portion of a swath of the image on the print medium, sensing the position of an edge of the just printed portion of the image which is nominally aligned with the scan axis; providing relative motion between the print medium and the printing element to accurately position the printing element in dependence on the sensed position of the edge of the just printed portion of the image. The fine compensation needed to compensate positioning errors can be performed prior to printing a swath, or even “on the fly” during the printing of a swath. Coarse positioning errors can be measured by the sensor and compensated by use of the printer media advance system, by increasing or decreasing as appropriate the nominal commanded swath-to-swath advance distance.

摘要： A vacuum holddown has a holddown member with an outer surface for temporarily capturing a flexible sheet material via a vacuum force distributed across the outer surface through discrete vacuum channels. A vacuum force valve mechanism abuts an inner surface of the holddown member in a selectable sliding engagement. The valve mechanism has a pattern of apertures therethrough in predetermined pattern such that discrete valve mechanism positions produce discrete vacuum force patterns at the outer surface of the holddown member.

摘要： A method of calibrating a media advance mechanism in a printer utilizes an optical sensor of the printer to detect printed marks on a calibration sheet. The marks on the calibration sheet are spaced at actual longitudinal intervals. The calibration sheet is advanced longitudinally past the printhead carriage, and the calibration marks are detected with the optical sensor. The printer determines the apparent or measured longitudinal intervals and compares them to the actual intervals to determine errors in positioning the calibration sheet.

摘要： The present invention addresses the problem of paper cockle by stretching the paper as it progresses along the paper path through the wet colorant printing station of a hard copy apparatus. The hard copy apparatus uses a paper feed belt system as a paper platen in which the belt or set of belts is splayed along the paper path. Firmly adhering a sheet of print media to the belt, or belts, system, such as by use of a vacuum force, as it travels through the apparatus printing zone, stretches the media orthogonally and particularly in an orientation perpendicular to the paper path.

摘要： A method and mechanism for cleaning a paper transport belt of undesirable ink deposits caused by ink-jet aerosol and printing overshoot operations uses a special cleaning medium. An absorbent material is positioned in the print zone of a hard copy apparatus to scrub the belt. An ink solvent is used to rehydrate dried ink. The scrubber can be in the form of consumable sheets or a continuous roll form.

摘要： A belt tracking system for an endless belt having left and right opposed edges, the belt driven in a first direction by a belt drive system. The tracking system includes a set of periodic belt indicia formed on the belt along one or more axes aligned with the first direction. A sensor system tracks movement of the belt in a lateral direction transverse to the first direction and senses the set of belt indicia to provide sensor system signals. An actuator system effects movement of the belt in the lateral direction, the actuator system responsive to the sensor system signals for nominally maintaining a position of the belt relative to the transverse direction. A controller is responsive to the sensor system signals for detecting that the belt has tracked outside an allowable belt movement range and taking protective actions to prevent the belt from damage due to undesired lateral tracking movement. A belt indicia sensor can optionally be employed to calibrate a belt drive system.

摘要： A media advance system is driven using a fixed-differential, planetary belt drive system. Planetary pulleys, mounted to a mounting structure, orbit a motor shaft as the mounting rotates about the motor shaft. A first planetary pulley is coupled by a drive belt to a fixed pulley. The fixed pulley does not rotate and is aligned to the motor shaft, so the planetary pulley is forced to rotate while orbiting. A second planetary pulley rotates and orbits with the first. An output pulley is coupled to the second planetary pulley by another drive belt. An output shaft is coupled to the output pulley. Drive ratio of the output shaft to the motor shaft is based upon the diameters of the fixed pulley, first planetary pulley, second planetary pulley, and output pulley. Noise is low by using belts rather than meshing gears. Variable differentiation is achieved in another embodiment.
