    • A sensor for sensing and identifying characteristics of a printer ink ribbon when a ribbon supply roll is inserted into a printer and operated. Ink ribbon cartridges used in printers are provided in a number of types, colors, and other identifiable characteristics that are important for insuring that the correct ribbon is inserted in the printer for the then current print job. In the present invention, the ribbon cartridges include ribbon supply rolls which are provided with identifying indicia on one end of the roll, and a sensor to read the presence of indicia when the printer is operated. The positions of the indicia relative to selected reference positions indicates the ink ribbon type. Suitable circuitry is used to disable the printer if the print ribbon is not properly correlated to the requirements of the printer. A Hall Effect Sensor is used adjacent the print roll, and the indicia on the ink ribbon roll comprise pins or similar members that will affect the Hall Effect Sensor output when rotated past the sensor.
    • 一种传感器,用于在将色带供给辊插入打印机并操作时感测和识别打印机墨带的特性。 在打印机中使用的墨带盒提供多种类型,颜色和其他可识别的特性,这对于确保当前打印作业中正确的色带被插入到打印机中是重要的。 在本发明中,色带盒包括色带供给辊,其在辊的一端设置有识别标记,以及传感器,用于在打印机操作时读取标记的存在。 标记相对于所选参考位置的位置表示色带类型。 如果打印色带与打印机的要求没有正确关联,则使用合适的电路来禁用打印机。 在打印辊附近使用霍尔效应传感器,墨带上的标记包括销或相似的构件,当旋转经过传感器时,会影响霍尔效应传感器的输出。

    • An arrangement for acquiring signal representatives intended to correspond to character representations, out of a set of possible character representations, provided on a substrate that emanate magnetic fields which can be sensed to provide a related waveform. Times of extrema of the waveform are ordered and compared with the ordering of time locations in waveforms expected for the set of possible characters with different orderings being used to eliminate those possible characters having expected waveforms incompatible with the extrema ordered times of the measured waveform.
    • 一种用于获取旨在对应于一组可能的字符表示中的字符表示的信号代表的装置,其提供在发出可被感测以提供相关波形的磁场的基板上。 对波形的极值的时间进行排序,并将其与具有不同顺序的可能字符集的预期波形的时间位置的顺序进行比较,以消除具有与测量波形的极值有序时间不兼容的预期波形的可能字符。

    • A method of controlling a thermal print head having a plurality of resistive heaters to compensate for the effects of latent heat from the resistive heaters is disclosed. The plurality of resistive heaters are arranged in a line on a substrate with each of the plurality of resistive heaters corresponding to a pixel position on a medium such as paper. A compensation value is determined for each pixel in a line such that the effects of latent heat from the corresponding heater and from adjacent heaters are compensated. A compensated gray level for each pixel of the line is calculated as a function of a desired gray level for the particular pixel in the line and as a function of the associated compensation value. Finally, the heaters are driven as a function of the compensated gray levels to print the corresponding pixels of the line.

    • Identification card manufacturing security restricts use of an identification card manufacturing system with only authorized supplies. In accordance with one aspect of the invention, a supply-specific security code (SSSC) and supply-specific data are stored in memory of the supply. The SSSC is translated using the supply-specific data. Finally, the supply is authorized for use with the identification card manufacturing system only when the translated SSSC is found to be valid. In accordance with another aspect of the invention, an identification card manufacturing system is configured to operate only with supplies having corresponding customer-specific security codes (CSSC). A supply CSSC and supply-specific data are retrieved from memory of the supply. Additionally, a system CSSC and system-specific data are retrieved from memory of the identification card manufacturing system. The supply CSSC and the system CSSC are translated using the supply-specific data and the system-specific data, respectively. Finally, the supply is authorized for use with the identification card manufacturing system when the translated system CSSC and the translated supply CSSC correspond.
