摘要： A thermal printer has a dye donor supply spool with a body and first and second end portions extending from the body. First and second receptacles are positioned for matingly receiving the first and second end portions of the dye donor supply spool. The supply spool is correctly loaded only when the first and second end portions of the supply spool matingly engage the first and second receptacles, respectively. A mechanical stop prevents incorrect end for end loading of a supply spool that has an off center web wound thereon by engaging the web and preventing the end of the spool from engaging the receptacle.

摘要： A color thermal printer loads a dye receiver for printing by moving the dye receiver in a first direction through a gap between a print head and a platen. A dye donor, also positioned in the gap, moves in the first direction during receiver loading. The moving dye donor engages the dye receiver, assisting the dye receiver through the gap. When the dye receiver is detected downstream of the gap, the dye receiver is positioned in a beginning receiver print position and the position of the dye donor with respect to the print head is determined. If the print head position is downstream of a beginning donor print position, the dye donor is rewound in a second direction opposite the first direction until the print head is upstream of the beginning donor print position, whereupon the dye donor is moved to the beginning donor print position. If the print head position is upstream of the beginning donor print position when the dye receiver is detected, the dye donor is moved to the beginning donor print position. A normal printing sequence occurs when both dye donor and dye receiver are in their respective beginning print positions.
摘要翻译： 彩色热敏打印机通过沿着第一方向移动染料接收器通过打印头和压板之间的间隙来装载用于打印的染料接收器。 也位于间隙中的染料供体在接收器加载期间沿第一方向移动。 移动的染料供体与染料接收器接合，通过间隙辅助染料接收器。 当在间隙的下游检测到染料接收器时，染料接收器被定位在开始的接收器打印位置，并确定染料供体相对于打印头的位置。 如果打印头位置在开始的供体打印位置的下游，则染料供体在与第一方向相反的第二方向上重新卷绕，直到打印头位于起始供体打印位置的上游，于是将染料供体移动到起始供体 打印位置。 如果当检测到染料接收器时打印头位置在开始施主打印位置的上游，则染料供体移动到开始的供体打印位置。 当染料供体和染料接收器处于它们各自的开始印刷位置时，发生正常的印刷顺序。

摘要： The present invention relates to techniques for ensuring that an image receiving sheet, which has only one major surface thereof coated with an image receiving coating, is properly oriented prior to an image being printed thereon. The image receiving sheet has a concave or convex irregularity (e.g., a notch, arc, etc.) formed in at least one nominally straight edge of the sheet. In a first embodiment, a mechanical or optical sensing means detects whether or not the image receiving sheet is stacked correctly in a loading tray by sensing whether or not the edge irregularities are properly positioned. In a second embodiment, an edge and a notch sensing means detect whether or not the image receiving sheet is oriented properly while being fed into the printer. An improperly loaded image receiving sheet is either not fed into the printer, or transits the printer without causing the printer to attempt to print the image thereon. A visual and/or audible alarm can be activated upon the detection of an improperly loaded image receiving sheet to apprise a printer operator of the improperly loaded sheet.
摘要翻译： 本发明涉及用于确保仅在其一个主表面上涂覆有图像接收涂层的图像接收片材在其上打印图像之前被适当地定向的技术。 图像接收片具有形成在片材的至少一个标称直线边缘中的凹或凸不规则（例如，凹口，弧形等）。 在第一实施例中，机械或光学感测装置通过检测边缘不规则是否适当定位来检测图像接收片是否正确地堆叠在装载盘中。 在第二实施例中，边缘和凹口检测装置检测图像接收纸张在被送入打印机期间是否正确定向。 不正确加载的图像接收纸张未被送入打印机，或者转印打印机，而不会导致打印机尝试在其上打印图像。 检测到不正确的图像接收纸张时，可以启动视觉和/或听觉报警，以向打印机操作员通知不正确加载的纸张。

摘要： Apparatus for clamping receiver sheets to the print drum of a thermal transfer printer. The apparatus includes a clamp assembly mounted for radial movement and having a clamp strip extending over the drum periphery and an interior longitudinal body coupled to that strip at a plurality of axially spaced locations. A longitudinal lever member extends axially within the drum from a pivot point at one drum end to an actuation arm at the other drum end and has a pivot arm coupled to a central portion of the clamp body. Springs urge the clamp assembly radially inwardly and an actuator mounted on the other drum end selectively moves the lever member radially outwardly.

摘要： A thermal printer has a platen roller and a moveable print head. A paper guide is positioned for guiding a sheet receiver media to an entrance between the platen and the print head when the print head is in the nonprinting position. A capstan pinch roller is movable relative to a capstan roller to grip the dye receiver therebetween. The capstan roller meters the receiver in a forward direction along the paper guide prior to metering the receiver in a reverse direction not along the paper guide and again in the forward direction not along the paper guide. The receiver media travels along two different transport paths.

摘要： A nip-roller pair for transporting a sheet or web of material has one regular roller and a special roller to prevent scarring of the transported material. The special roller has one or more hubs of soft, compressible material that engage the material and hold the material away from the harder, rougher surface of the roller. The rollers close to compress the hubs and transport the material
