摘要： A fluid (liquid or water) wash is used to clean the front surface of an ink jet printer cartridge. In addition, a nozzle plate that overlies the nozzle shields the nozzle array from the splatter of ink. In ink jet printers, ink droplets are propelled from an array of orifices in a nozzle plate in the printer head. During the ink droplet ejection, ink is sprayed or deposited around the orifices. The ink droplets are deposited on a paper web adjacent the nozzle and mist from the droplets drifts back to coat the face of the nozzle plate. Some ink seeps behind the nozzle plate onto the array of nozzle orifices. The ink coating attracts particles that tend to clog the nozzle orifices. The ink coating is washed away by fluid streams that flow over the nozzle surface and in some embodiments flow over the nozzle orifices themselves. The fluid may be water, ink or other liquid that is channelled across the nozzle surface, or the fluid may be an air stream that blows across the nozzle surface.

摘要： In a printer assembly having a rack of ink-jet print cartridges, a backup cartridge is moved into alignment with a cartridge to be cleaned and the backup cartridge substitutes for printing of the cartridge being cleaned until the cleaned cartridge is moved back to its printing position. The backup cartridge is then moved into alignment with another cartridge and prints for that cartridge which is then cleaned. Ink-jet print cartridges must be periodically cleaned to wipe excess ink and particles from the nozzle array on the front face of the cartridge. Cartridges are cleaned by moving them to a cleaning station that wipes clean the front face of the cartridge. To avoid interruption of printing while cartridges are being cleaned, a backup cartridge is moved into alignment and substitute prints for a cartridge to be cleaned.
摘要翻译：在具有喷墨打印墨盒架的打印机组件中，将备用墨盒移动成与要清洁的墨盒对准，并且备用墨盒代替正在清洁的墨盒的打印，直到清洁的墨盒移回其打印位置。然后将备用墨盒移动到与另一个墨盒对齐并打印该墨盒，然后将其清洁。必须定期清洁喷墨打印墨盒，以从墨盒前表面上的喷嘴阵列中清除多余的墨水和颗粒。通过将墨盒移动到清洁墨盒的前面的清洁站清洁墨盒。为了避免在清洁墨盒时打印中断，将备用墨盒移动到对齐位置，并替换要清洁的墨盒的打印件。

摘要： Substantially optimum print quality is maintained for an ink jet printer which includes a nozzle plate having a number of orifice openings from which ink droplets for printing are sprayed. It is electronically determined when a particular orifice opening has been inactive for a predetermined period of time, and then an exercise print command is supplied to the orifice causing an ink droplet to dribble out of the orifice, rather than being sprayed out of the orifice, to keep the orifice clear for printing when a print command is supplied to it. The dribbling drops have a smaller size than the sprayed drops, and may be formed by supplying heater elements associated with the openings with pulses of shorter duration than normal. Dribbling ink droplets are automatically removed from the printer cartridge by one or more strands (e.g. continuous filament rayon thread) moving past the nozzle at a speed of between about 1-3 feet per hour while being positively guided.
摘要翻译：对于喷墨打印机来说，维持基本上最佳的打印质量，喷墨打印机包括具有多个孔口的喷嘴板，喷墨用墨滴从喷嘴板喷出。当特定孔口已经停止预定的时间段时，它是电子地确定的，然后向孔口提供运动打印命令，使得墨滴从孔中运出而不是从孔口喷出，当打印命令提供给它时，保持孔口清洁以进行打印。滴液滴具有比喷雾液滴更小的尺寸，并且可以通过以比正常持续时间短的脉冲提供与开口相关联的加热器元件形成。通过一个或多个股线（例如连续细丝人造丝线），通过一个或多个股线（例如连续长丝人造丝线）自动地将墨滴从打印机的速度移动到大约1-3英尺/小时的同时被积极引导。

摘要： A modular ink delivery system using ink jet heads effectively supplies ink to a multi-level array of ink jet heads, and ensures that the heads remain in position during printing even if there is vibration of the supporting structures. Delivery is provided by a number of ink containing chambers, at least one for each level and stacked one atop the other. A connection extends from each chamber to at least one ink jet, and ink is automatically supplied to all of the chambers for example by pumping ink to the upper of the chambers, the ink then cascading downwardly from each upper chamber to a lower chamber through standpipe connections between them. The heads are positively held in place by a first circular bar and a second non-circular bar, which bars are operatively engaged by a mounting block for each head for guided movement. A tightenable screw and spring plunger may cooperate with an arcuate bushing for engaging the first bar, and a channel on a releasable clip and rollers on a portion of the mounting block may engage the second bar.
摘要翻译：使用喷墨头的模块化墨水输送系统有效地将油墨供应到喷墨头的多级阵列，并且确保在打印期间头部保持在适当位置，即使是支撑结构的振动。输送由多个含有墨水的腔室提供，至少一个用于每个级别并且堆叠在一起。连接从每个室延伸到至少一个喷墨，并且油墨例如通过将油墨泵送到室的上部而自动地供应到所有室，然后油墨从每个上室向下通过立管他们之间的联系。头部通过第一圆形杆和第二非圆形杆被牢固地保持在适当位置，该杆通过用于每个头部的安装块可操作地接合以用于引导运动。可紧固的螺钉和弹簧柱塞可以与用于接合第一杆的弧形衬套配合，并且可释放夹子上的通道和安装块的一部分上的辊可以接合第二杆。
