摘要： The new heater element design has a pit layer which protects the overglaze passivation layer, PSG step region, portions of the Ta layer and dielectric isolation layer and junctions or regions susceptible to the cavitational pressures. Further, the inner walls of the pit layer define the effective heater area and the dopant lines define the actual heater area. In alternative embodiments, the dopant lines define the actual and effective heater areas, and an inner wall and a dopant line define the actual and effective heater areas. Further, when the new heater element designs are incorporated into printheads having full pit channel geometry and open pit channel geometry, the operating lifetime of the printhead is extended because the added protection of the pit layer prevents: 1) passivation damage and cavitational damages of the heater elements; and 2) degradation of heater robustness, hot spot formations and heater failures well into the 109 pulse range. The printhead incorporating the new heater element design can be incorporated into drop-on-demand printing systems of a carriage type or a full width type.

摘要： A method and apparatus for drying liquid ink deposited, in response to image data, on a recording medium moving along a path at a predetermined rate. A recording medium having liquid ink deposited thereon is moved past a dryer in multiple passes to dry areas of high ink coverage. Ink characteristics are optimized for minimum print defects by determining the time between printing and drying. In the case of text only images only one pass through the dryer is required. For areas of high ink coverage, however, multiple passes through the dryer are required and completed either by reciprocation or recirculation at the same predetermined rate.
摘要翻译：一种用于干燥液体墨水的方法和装置，其响应于图像数据在沿着路径以预定速率移动的记录介质上。具有沉积在其上的液体油墨的记录介质在多次通过干燥器之后被移到高油墨覆盖的干燥区域。油墨特性通过确定打印和干燥之间的时间来优化最小打印缺陷。在仅文本的情况下，仅需要一个通过烘干机的图像。然而，对于高油墨覆盖的区域，需要多次通过干燥器并且以相同的预定速率往复运动或再循环完成。

摘要： A method and apparatus for controlling the volume of ink droplets ejected from thermal ink jet printheads is disclosed. The electrical signals applied to heating elements for generating droplet ejecting bubbles thereon are composed of packets of electrical pulses. Each pulse and spacing therebetween are varied in accordance with one or more whole, clock or timing units. The number of pulses per packet and width of pulses and spacing therebetween are controlled in accordance with the manufacturing tolerance variations, the location of the addressed heating element in the printhead, the number of parallel heating elements concurrently energized, and optionally the temperature of the printhead in the vicinity of the heating elements to maintain the desired volume of the ejected droplets.

摘要： A multi-pass printbar for providing full width printing on a recording medium is provided. The full width printing may be achieved by stepping the printbar in increments corresponding to the combination of the array width of a printhead die and the gap spacing between the printhead dies until full width print coverage on the recording medium occurs. Ink is ejected from an array of orifices on the printbar as the recording medium passes under the printbar. Alternatively, the full width printing may be achieved by fixing the printbar, and its array of orifices, but stepping the document handler, for example a recirculating drum document handler, the recording medium is mounted upon as it passes under the fixed printbar. Yet another alternative provides full width printing by providing a combination of motions of the printbar and a recirculating drum document handler simultaneously such that the printbar moves continuously and at a constant rate in a linear fashion while the recirculating drum document handler rotates the recording medium under the linearly moving printbar. The result is a “barber pole” style placement of printing information ink droplets on the recording medium which occurs repeatedly due to the rotational recirculation of the recording medium on the drum under the linearly moving printbar until full width print coverage is achieved.

摘要： An ink jet printer is configured in a hybrid architecture wherein a full width printbar is combined with a partial width color scanning assembly to provide the capability of selectively printing in black only or, alternately, of producing color prints by operating the color scan assembly exclusively. The cost of the hybrid system, when compared to a full width color system using four full width printbars, is greatly reduced. Throughput time is reduced by providing the control circuitry for distinguishing between black only and color operation and selectively controlling the printer mode of operation. The hybrid architecture is particularly useful in a LAN system since it provides a mechanism for balancing the relative color versus black page decomposition speed limitations. Also, the hybrid architecture enables a relatively simple implementation of a checkerboarding technique to suppress banding in output prints.
摘要翻译：喷墨打印机被配置为混合架构，其中全宽度打印条与部分宽度彩色扫描组合组合，以提供选择性地以黑色打印的能力，或者通过专门操作彩色扫描组件来产生彩色打印。与使用四个全宽度打印棒的全幅彩色系统相比，混合系统的成本大大降低。通过提供用于区分黑色和彩色操作的控制电路并选择性地控制打印机操作模式来减少吞吐时间。混合架构在LAN系统中特别有用，因为它提供了用于平衡相对颜色与黑色页面分解速度限制的机制。此外，混合架构使得能够相对简单地执行棋盘棋技术来抑制输出打印中的条带。

摘要： An electrohydrodynamic stimulated ink jet printing device and method of manufacture which eliminates the prior art problem of ink wetting the dielectric spacer between the stimulating electrode and the ink jet nozzles. The nozzles are electroformed on one side of a sheet of dielectric material and the EHD electrodes are electroformed on the other side of the dielectric material in registration with the nozzles. The dielectric material is removed from the nozzles by using the nozzles or the electrodes as masks. The internal surface of the dielectric material is coated with a one of a number of coatings non-wettable by the ink such as a mixture of paraffin and ethylene vinyl acetate copolymer dissolved in a light aliphatic hydrocarbon, such as VMP naphtha.

摘要： A plurality of disposable, individually replaceable ink supply cartridges are mountable on the carriage of an ink jet printer. Each cartridge has a thermal printhead fixedly attached thereto. A constant slightly negative pressure is maintained at the nozzles of the printhead by means of a secondary reservoir with a level of ink maintained below the ink supply. The majority of the ink is stored in a hermetically sealed main reservoir in the cartridge which contains the ink supply at the negative pressure. A passageway provides ink from the main reservoir to the printhead nozzles. The secondary reservoir holds an air pocket at atmospheric pressure and releases air into the main reservoir as required to maintain the desired negative pressure constant therein as the ink supply is depleted. The passageway entrance is sized to maintain a meniscus when the cartridge is tilted to prevent loss of the desired nozzle pressure by air from the second reservoir. A membrane filter passes air to the secondary reservoir, but is impervious to ink. Means to reduce the effects of fluid inertia on the ink caused by sudden changes of printing duty cycles is optionally provided.

摘要： A thermal ink jet printer including a frame, a printhead mounted to the frame for printing ink images onto a heated and supported substrate, and an efficient substrate heating and supporting assembly mounted to the frame. The efficient substrate heating and supporting assembly includes a heating device, and a substrate supporting member having a front surface including a substrate supporting area for supporting substrates of various sizes one at a time and border areas having a polished finish. The efficient substrate heating and supporting assembly also includes a heat absorbing back surface facing the heating device. The heat absorbing back surface includes an increased heat absorbing area located opposite and centered relative to the substrate supporting area on the front surface. The increased heat absorbing area, relative to a rest of the back surface, has a coat of paint thereon for increasing heat absorption thereinto from the heating device, thereby resulting advantageously in relatively nonuniform heat absorption into the back surface, and relatively in more uniform, adequate and efficient substrate heating and drying temperatures on the front surface, when continuously running a most often run size of substrates.
