摘要： A printhead for printing ink includes a particulate filter manufactured from a polymer sheet such as a polyimide sheet. Filter openings within the particulate filter can be formed using a mask and a laser beam to ablate exposed portions of the polymer sheet. Embodiments of the present teachings can result in the formation smaller filter openings at a smaller pitch within the polymer sheet than, for example, stainless steel particulate filters, and thus more openings which cover a larger percentage of the filter surface for a given filter size, which can result in a reduction of fluid pressure within the printhead. Thus smaller filter openings for improved filtering of smaller particulates can be formed while maintaining a sufficient ink flow at a sufficiently low pressure within the printhead during operation.
摘要翻译：用于印刷油墨的打印头包括由诸如聚酰亚胺片材的聚合物片材制成的微粒过滤器。可以使用掩模和激光束来形成微粒过滤器内的过滤器孔，以消除聚合物片的暴露部分。本教导的实施例可以导致在聚合物片材内以比例如不锈钢颗粒过滤器更小的间距形成更小的过滤器开口，因此，对于给定的过滤器尺寸，覆盖更大百分比的过滤器表面的更多的开口，这可能导致打印头内的流体压力的降低。因此，可以在操作期间形成用于改善过滤较小颗粒的较小的过滤器开口，同时在打印头内保持足够低的压力下的足够的油墨流动。

摘要： Systems and methods of ejecting ink drops from an inkjet printer are disclosed. The systems and methods can include a printhead with one or more actuators with associated nozzles and membranes. A voltage waveform can be applied to the actuators to fill the actuators with a volume of ink and eject the ink through the nozzles as ink drops. The voltage waveform can have associated pre-fill voltage to fill the actuator with ink and a firing voltage to eject the ink. The actuator membranes can have multi-height dimples to protect the membranes from contacting electrodes and reduce the electric field.

摘要： A system and method to provide pressure to de-prime a printhead. An image forming device comprises an ink reservoir that contains ink and provides the ink to a printhead. When a fault condition is detected that indicates a likelihood of a solidifying of the ink, the printhead is de-primed by applying pressure to the printhead to purge the ink from the printhead. The fault condition comprises any of a loss of power, a power-down process, or a printhead temperature being less than or equal to a threshold temperature.

摘要： An ink jet recording apparatus includes a die reservoir and at least one ink channel in communication with the die reservoir. The method and apparatus contemplate heating ink in the die reservoir to increase vapor pressure of the ink to cause mass transfer of water vapor molecules across an interface between the air bubble and the ink and removing air bubbles entrapped within the die reservoir and the ink channel. An ink jet recording apparatus may also include a heat sink provided to the die reservoir to cool the die reservoir below predetermined threshold temperatures. The heat sink may be fixably attached to either a carriage or maintenance station of the ink jet recording apparatus, or the heat sink may be integrally formed with the die reservoir and the ink channel as part of the replacement cartridge.
