摘要： A thermal demand printer for printing on media is a novel system which includes a case structure including a hinged cover panel, easily removable guide structures and media hanger, and a single central support wall to which the various components are attached. The printer includes a power supply circuit for receiving power from an external source and conditioning it for operation of the printer. An input device is provided for receiving command signals related to the operation of the printer. A control circuit for processing the command signals and generating corresponding control signals for controlling the operation of the printer and a printhead assembly for processing the control signals and generating corresponding control signals for controlling the operation of the printer are mounted in the case structure and coupled to the input device and the power supply circuit. The printhead assembly includes a printhead support structure which controls the printhead. A ribbon take-up spindle, method of operating the take-up spindle using a PMDC motor, and a spring wrap clutch device help to control the tension in the transfer ribbon used in the printer. The printer also includes a medial sensor and a method of sensing media by way of detecting the opacity of the media passing through the sensor. The printer includes a method of printhead control using double data loading and a method of accelerating and decelerating media relative to the printhead using pulse width modulation.

摘要： Disclosed herein is a ribbon wiper that is disposed within a ribbon cartridge. The ribbon cartridge can contain a ribbon and be employed by a thermal printer. The ribbon wiper is capable of removing debris and other contaminants from a printhead surface of the ribbon. The printhead surface of the ribbon is that surface that faces the printhead, and opposes the ink surface of the ribbon, during printing. Debris disposed on the printhead surface of the ribbon can hinder or obstruct thermal contact between one or more thermal elements on the thermal printhead. In such cases, the thermal element can lack the ability to properly produce a dot on a media as instructed by the thermal printer. Further, debris disposed on the printhead surface of the ribbon can accumulate on the printhead proximate thermal elements and prevent generation of multiple or consecutive dots. If the collection of debris continues, thermal elements can ultimately be disabled causing voids, streaks, and scratches to undesirably appear in a printed image. Ribbon rollers can bias the ribbon toward, and upon, the ribbon wiper. Also, ribbon rollers, as well as a take-up roller, can supply tension to the ribbon to urge the ribbon toward, and upon, the ribbon wiper. Further, the ribbon wiper can be replaced simultaneously with the ribbon cartridge when the supply of ribbon within the ribbon cartridge is exhausted.
摘要翻译： 本文公开了一种设置在色带盒内的色带刮水器。 色带盒可以包含色带并由热敏打印机使用。 色带刮水器能够从色带的打印头表面去除碎屑和其他污染物。 在打印期间，色带的打印头表面是面向打印头的表面，并与色带的油墨表面相对。 设置在带的打印头表面上的碎屑可阻碍或阻碍热打印头上的一个或多个热元件之间的热接触。 在这种情况下，热敏元件可能缺乏在热敏打印机的指示下在介质上正确地产生点的能力。 此外，布置在带的打印头表面上的碎屑可以在打印头上积聚在热元件上，并且防止产生多个或连续的点。 如果碎片的收集继续下去，则热元件最终将被禁用，导致空白，条纹和划痕不期望地出现在印刷图像中。 色带辊可以将色带偏置到色带刮水器上。 此外，色带辊以及卷取辊可以向色带供应张力，以将色带推向色带刮水器。 此外，当色带盒中的色带供应耗尽时，色带刮水器可以与色带盒同时更换。

摘要： There is disclosed a thermal transfer printer utilizing a one time ink sheet or a multi-print ink sheet. In order to avoid sticking of the ink sheet and the recording sheet, for example where there is an interruption in facsimile transmission or when a recording interval exceeds a predetermined time, the thermal head is energized to maintain a high temperature state and then the recording paper is transported by a predetermined amount, thereby separating the ink sheet and the recording paper.

摘要： A demand printer has an input structure for receiving command signals related to the operation of the printer; a control circuit coupled to the input structure, and a power supply circuit for processing command signals and generating corresponding control signals for controlling the operation of the printer. A switch circuit line is coupled to at least a first and a second point on the power supply circuit. The switch circuit line provides a first operating voltage for the operation of the printer when connected between the first and second points in the power supply circuit and provides a second operating voltage when the connection between said first and second points is opened by a severing structure. The severing structure projects into a base cavity of the case and is retained therein for maintaining an open circuit between the first and second points on the power supply circuit once said switch circuit line is severed. The severing structure includes a wall of the base cavity which has an control aperture extending therethrough, a severing body having a head end and a severing end wherein the severing end projecting through the control aperture and contacting and severing the switch circuit line; a retaining segment on the severing body operatively associated with the case when the severing body is inserted through the control aperture for retaining the severing body in contact with the switch circuit line to maintain an open circuit between the first and second points.

摘要： A demand printer for printing on media includes a ribbon take-up spindle for accumulating spent printing ribbon and facilitating removal of the spent ribbon from the spindle. The spindle has a surface with a protrusion bore formed therethrough. At least one protruding segment extends through the protrusion bore. The protruding segment controllably projects away from the spindle surface for maintaining a space between a portion of the spindle surface and the spent ribbon accumulated on the spindle. A biasing structure is operatively associated with the spindle and the protruding segment for controllably biasedly directing the protruding segment through the protrusion bore in the spindle. A retracting structure is provided for controllably compressing and expanding the biasing means to controllably move the protruding segment through the protrusion bore.

摘要： A thermal demand printer for printing on media is a novel system which includes a case structure including a hinged cover panel, easily removable guide structures and media hanger, and a single central support wall to which the various components are attached. The printer includes a power supply circuit for receiving power from an external source and conditioning it for operation of the printer. An input device is provided for receiving command signals related to the operation of the printer. A control circuit for processing the command signals and generating corresponding control signals for controlling the operation of the printer and a printhead assembly for processing the control signals and generating corresponding control signals for controlling the operation of the printer are mounted in the case structure and coupled to the input device and the power supply circuit. The printhead assembly includes a printhead support structure which controls the printhead. A ribbon take-up spindle, method of operating the take-up spindle using a PMDC motor, and a spring wrap clutch device help to control the tension in the transfer ribbon used in the printer. The printer also includes a medial sensor and a method of sensing media by way of detecting the opacity of the media passing through the sensor. The printer includes a method of printhead control using double data loading and a method of accelerating and decelerating media relative to the printhead using pulse width modulation.
