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.

摘要： A chip used for dispensing a fluid such as ink provides ink-dispensing ejectors having an ink cavity over a supporting substrate, and further provides a heater for heating the ink in the cavity. The heater can be interposed between the substrate and the ink cavity to provide direct heating of ink as it is being dispensed. Various embodiments further comprise the use of the heater structure as a temperature probe to measure the temperature of the ink in the ink cavity. Other embodiments provides a chip having both a temperature probe and a heater as separate structures interposed between the ink cavity and the substrate. Further described is a temperature probe and/or heater which traverses a majority of a width of a substrate, and surrounds each drop ejector on at least two sides.

摘要： A method and apparatus for removing dissolved air in ink and air bubbles or air pockets from ink passageways in ink jet printer cartridges by use of a permeable membrane tubing member positioned in the ink at a location adjacent the ink inlet of the printer's droplet ejecting printhead. The permeable membrane tubing member is connected to a vacuum source to diffuse air into the vacuum in the tubing member interior. The vacuum source may be by a direct connection to the printer's vacuum priming pump at its maintenance station, a separate vacuum pump, or a vacuum accumulator.

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。
