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 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 valving mechanism abuts an inner surface of the holddown member in a selectable sliding engagement. The valving 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 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.
摘要翻译： 使用固定差动行星传动系统驱动介质提前系统。 安装在安装结构上的行星滑轮随着安装座围绕电机轴转动。 第一行星滑轮通过传动带联接到固定滑轮。 固定滑轮不旋转并与电机轴对齐，因此行星滑轮在行驶时被迫转动。 第二行星轮与第一行星轮旋转并且轨道运动。 输出滑轮通过另一驱动带联接到第二行星滑轮。 输出轴联接到输出滑轮。 输出轴与马达轴的传动比基于固定滑轮，第一行星滑轮，第二行星滑轮和输出滑轮的直径。 使用皮带而不是啮合齿轮，噪音较低。 在另一个实施例中实现可变分化。

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： 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.
