摘要： A printing machine of the type in which liquid ink is deposited on a recording medium for printing gray scale images. The printing machine includes a printhead having ink ejecting nozzles of different sizes. Nozzles of the same size are arranged in groups and groups of nozzles are offset from one another. Ink drops of one group are deposited at locations corresponding to the points of a grid and ink drops of another group are deposited at locations corresponding to points not on the grid. Gray scale printing is achieved by the variation in drop size produced by different groups of nozzles as well as offsetting nozzles of one or more groups of nozzles from a reference group of nozzles printing on the points of a grid.

摘要： The invention discloses a system and method for sensing changes in the weight of an ink reservoir which supplies ink to a printhead which ejects ink onto a recording medium during a printer operational mode. The ink reservoir, whether located separately from the printhead, as in a plotter or pagewidth printer embodiment, or mechanically attached to the printhead and moved in a scanning printhead architecture, has its weight supported by a structure. A strain gage or other weight sensor is affixed to the supporting structure and incorporated in a circuit which produces an output signal representative of resistive changes in the weight sensor. Since a resistive change in the weight sensor is caused by a decrease in the supply of ink in the reservoir during continued printer operation, the output signal is proportional to the ink level. The output signal is digitized and sent to a system controller where it is compared to a predetermined reference level and a low level output signal is generated for use as a warning to a operator or user. In one embodiment, the strain gage is a leg of a resistor in a bridge circuit and provides continuous ink level readout. In another embodiment, multiple warning levels are enabled by inserting the resistor in a circuit where comparators compare the resistance of the strain gage to reference resistance levels.
摘要翻译： 本发明公开了一种用于感测墨水储存器的重量变化的系统和方法，该墨水储存器向在打印机操作模式期间将墨水喷射到记录介质上的打印头提供墨水。 油墨储存器，无论是与打印头分开设置，如在绘图机或页宽打印机实施例中，或机械地附接到打印头并以扫描打印头架构移动，其重量由结构支撑。 应变计或其他重量传感器固定到支撑结构上并且包括在产生表示重量传感器中的电阻变化的输出信号的电路中。 由于重量传感器中的电阻变化是由连续打印机操作期间储存器中墨水供应的减少引起的，所以输出信号与油墨水平成正比。 输出信号被数字化并发送到系统控制器，在那里将其与预定参考电平进行比较，生成低电平输出信号以用作对操作者或用户的警告。 在一个实施例中，应变片是桥接电路中的电阻器的腿，并且提供连续的墨水量读出。 在另一个实施例中，通过将电阻器插入电路中来实现多个警告电平，其中比较器将应变计的电阻与参考电阻电平进行比较。

摘要： A finishing apparatus adapted to receive and fasten collated sets of copy sheets is provided. The finishing apparatus includes a stacking tray in which successive sets of fastened copy sheets can be stacked. The copy sheets are compiled on a movable compiling member, a portion of which is positioned selectively over the stacking tray. A paper path is used to transport the copy sheets to both the stacking tray and the movable compiling member so as to position one portion of each copy sheet in the stacking tray with the remaining portion of each copy sheet being located in the movable compiling member. A fastener, such as a stapler is positioned adjacent to the movable compiling member. A retracting mechanism is employed to move the portion of the movable compiling member supporting the copy sheets away from both the copy sheets and the stacking tray after the copy sheets of the set of copy sheets have been fastened to one another so that the entire set of fastened copy sheets is supported in the stacking tray.

摘要： In a sorter for sorting sheets fed from a sequential source of sheets, with a closely vertically spaced array of sorter bins, and apparatus to vertically move the array of sorter bins relative to the source of sheets for sequentially loading individual sheets into individual sorter bins, the improvement including partially horizontally displacing one individual sorter bin at a time from the superposed array, in coordination with the vertical movement, towards the source of sheets to provide an enlarged bin entry opening without requiring any change in the vertical spacing between the bins, and subsequently horizontally moving a bin so displaced back into vertically superposed alignment with the other bins of the array. Also disclosed is stapling sheets sorted into the bins, wherein the same system for partially horizontally displacing the sorter bins also functions to move one displaced bin at a time into the stapler for stapling the sheets sorted in that bin without removal therefrom. The system for partially horizontally displacing the sorter bins may utilize individual pins connecting with respective individual sorter bins in a substantially vertically aligned array and an open jaw actuating system through which the array of pins is movable, which open jaw is adapted to engage and horizontally move a selected pin therein. An alternative cam track system with a horizontal displacement transition therein is also disclosed for this function.
