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： A banding adjustment method for an ink jet imaging device having a plurality of printheads comprises printing a plurality of test bands, each test band being printed by a plurality of printheads such that each printhead of the plurality prints a section of each test band. The drop mass generated by each printhead of the plurality is selectively adjusted between a default drop mass and an adjusted drop mass to print each test band of the plurality such that the plurality of printed test bands have various combinations of sections having the default drop mass and the adjusted drop mass. The user is then prompted to select a test band from the plurality of printed test bands.

摘要： A printhead reservoir has an input ink port and a chamber to receive ink from an ink source through the input ink port. The reservoir also has a filter in a path between the input ink port and the chamber. A printhead includes a reservoir having an input ink port, a chamber to receive ink from an ink source through the input port and a filter in a path between the input port and the storage plate. The printhead also includes an array of jets to draw ink from the chamber and control circuitry to control the jets so as to selectively output ink through the jets onto a substrate. A reservoir has a filter to receive ink, a vented chamber to collect ink received from the filter and at least one jet to receive ink from the vented chamber. The vented chamber is between the ink filter and the fluid path to the jets in order to remove the filter portion of the pressure drop to the jets.

摘要： An inkjet array has been developed that enables inlets for one group of inkjet ejectors to be laterally offset from the nozzles of the inkjet ejectors in the group and also enables inlets for another group of inkjet ejectors to be laterally offset from the nozzles of the inkjet ejectors in the other group. The lateral offset distance increases the distance between the inlets of the two groups to provide a wider bonding area between the two groups and improve the fluidic isolation between the two groups of inkjet ejectors.

摘要： An aperture plate for a print head of a printer can include a first layer having a first emissivity which is covered by a second layer having a second emissivity which is less than the first emissivity. In an embodiment, the second layer can be etched at nozzle locations to form openings in the second layer which have widths/areas greater than widths/areas of nozzles formed in the first layer. In another embodiment, the second layer can have a smaller thickness at the nozzle locations and a larger thickness away from the nozzle locations. Forming the openings in the second layer which are larger than the nozzles, or forming the second layer thinner at the nozzle locations prior to forming the nozzles, can provide a well-formed nozzle and an aperture plate having a low emissivity.
