    • A sheet indexing drive roller (10) has knurled drive portions (32, 34) on its opposite ends that are formed with spaced teeth (36) which partially penetrate into the sheet (22) being driven to form indentations. The teeth (36) are tapered and self centering so that when driving the paper (22) in reverse and forward direction the sheet (22) will be indexed as the teeth (36) slide into previously made indentation. As shown the teeth (36) are sharp pointed pyramidal shaped projections that are spaced apart a desired distance, and which have a vertical height (40) that is selected to be less than the thickness of the sheet (22) to prevent the points of the teeth (36) from piercing the side of the paper (22) that is being printed. The drive roller (10) finds an application in a wide variety of paper feed drives, and in particular is useful for driving sheets (22) that are to have labels printed on one side, and then cut into individual labels.
    • 片材分度驱动辊(10)在其相对端上具有滚花驱动部分(32,34),所述驱动部分形成有间隔开的齿(36),所述齿部分地穿透到被驱动的片材(22)中以形成凹陷。 齿(36)是锥形和自定心的,使得当齿轮(36)滑动到先前制成的凹口中时,当反向和向前方向驱动纸张(22)时,纸张(22)将被分度。 如图所示,齿(36)是间隔开所需距离的尖锐的棱锥形突起,并且具有选择为小于片材(22)的厚度的垂直高度(40),以防止 所述齿(36)刺穿正被打印的纸(22)侧。 驱动辊(10)可以应用于各种各样的进纸驱动器中,特别是用于驱动要在一侧打印标签的片材(22),然后切割成单独的标签。

    • A method of controlling a thermal print head (18) having a plurality of resistive heaters (H1...i) to compensate for the effects of latent heat from the resistive heaters (H1...i) is disclosed. The plurality of resistive heaters (H1...i) are arranged in a line on a substrate with each of the plurality of resistive heaters (H1...i) 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 (H1...i) are driven as a function of the compensated gray levels to print the corresponding pixels of the line.
    • 公开了一种控制具有多个电阻加热器(H1 ... i)以补偿来自电阻加热器(H1 ... i)的潜热的影响的热敏打印头(18)的方法。 多个电阻加热器(H1 ... i)在基板上排列成一行,多个电阻加热器(H1 ... i)中的每一个对应于诸如纸张的介质上的像素位置。 对于一行中的每个像素确定补偿值,使得来自相应加热器和相邻加热器的潜热的影响被补偿。 根据线中的特定像素的期望灰度级并作为相关补偿值的函数计算线的每个像素的补偿灰度级。 最后,加热器(H1 ... i)作为补偿灰度级的函数被驱动以打印线的相应像素。

    • A card processing device (100) includes a card input (113), a card feed path (114), a card processing mechanism (104), a card transport mechanism (102) and a card holder (101). The card processing mechanism is in the card feed path. The card processing mechanism includes a print head (116), a laminating roller (124) or a data reader/writer (128). The card transport mechanism includes a card feed roller (140). The card feed roller is configured to feed individual cards along the card feed path in a feed direction (160). The card holder is configured to support a stack (108) of card substrates (110) and provide the card feed roller access to a top card (110T) in the stack. The card holder includes a pivot member (152) positioned below the card feed roller and configured to pivotally support a bottom card (110B) of the stack of card substrates.
