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： An ink jet printer includes a printhead having a plurality of segments each having ink ejecting nozzles, each segment supplied with ink of a different characteristic. Means are provided for moving the printhead in a direction transverse to the advancing movement of a recording medium. Means are further provided for moving the printhead between two or more positions along the recording medium advance direction. Thus, the printhead can print a swath of ink of a first characteristic from one segment and then be moved to print a second swath from a second segment with ink of a second characteristic. In one embodiment, a printhead has two segments, one printing in black, and the other in color. A shift mechanism is enabled to move the printhead between a black print position and a color print position. The invention contemplates alternate color printing swaths at alternate printing positions along the same printing swath, or a combination thereof.

摘要： An ink jet printbar assembly is provided with a plurality of printhead die assemblies mounted on a single flat substrate. The printhead die assemblies are linearly aligned along the substrate length. Each die assembly includes a line of nozzles having the same active print length. The individual die assemblies are spaced from adjacent die assemblies such that the last functional nozzle on one end of a die assembly is spaced a distance which is less than the active print length from the first adjacent functional nozzle on the next adjacent die assembly.

摘要： A finishing apparatus for receiving and attaching sets of sheet material in succession. A movable bin array including plurality of bins are provided for receiving the sheet in each individual bin. Rollers are provided for transporting a copy sheet to the finishing apparatus to one of each individual bin. Registration of the sheet is accomplished by the uphill nature of the each individual bin in the bin array sloping towards a registering portion of a gate assembly, and the action of a tamper mechanism registers the sheets. A stapling means having a cam that is radially urged moves in a plane substantially parallel to the orientation of the the bin array. The action of the cam drives the stapler means into a notched area of each individual bin positioned thereat so that registered sheet sets therein may be stapled in the notched area. The action of the stapler means also opens the gate on an adjacent bin so that a retaining gate on each individual bin are moved to an output of the way position enabling sheet sets therein to slide off each individual bin onto a guide support and into the output tray.

摘要： An ink jet printer includes a platen having a planar surface sized to hold a sheet upon which an image is to be printed flat on the planar surface. The platen is movably mounted for linear reciprocal movement between a sheet receiving position and a sheet releasing position. In operation, a sheet is fed onto or otherwise acquired on the platen. The sheet can be held on the platen by a holddown force such as by vacuum or electrostatic attraction. The platen moves a sheet held thereon across a full width printhead located between the two positions to print an image on the sheet. Sheets are released from the platen at the sheet releasing position which may include an output tray. After the sheet is released from the platen, the platen is reciprocated back to the receiving position to accept another sheet. During periods when the platen is at either the sheet receiving position or at the sheet releasing position, a maintenance station located between the receiving position and the releasing position on a side of the platen opposite from the printhead may be used to perform maintenance on the printhead.

摘要： An ink supply for an ink jet printer, preferably comprises a bellows filled with liquid ink. The bellows has first and second opposite end walls and a bellowed side wall attached to and extending between the first and second end walls to define a variable volume ink chamber. The bellows is movable between an extended position and a contracted position and is biased toward the contracted position. The first end wall includes an outlet which, when opened, permits the ink to be expelled from the bellows at a low pressure. A rigid frangible shell is provided to support the bellows and to retain the bellows in an extended position during storage and prior to use. The bellows may include a magnet which, when used in combination with a printer and a sensing device, can detect and signal a near empty or empty ink supply condition.

摘要： The pages of a book being held at least partially open may be sequentially automatically turned over from one side of the book to the other by pivoting an elongated arm from one side of the book toward the other and turning over individual pages with a vacuum head pivoting relative to the elongated pivoted arm about a different pivot axis as the elongated arm moves to reduce undesirable forces on the individual book pages being turned over. The vacuum head may initially pivot to bend the edge of an individual page up away from the book, to aid in page separation, and then subsequently differently pivot to help peel the same page gently away from the vacuum head and flip it over onto the opposite side of the book. This may be assisted by moving frictional belts on the vacuum head.
