摘要： A filter structure having a plurality of pores through the structure each of the pores having a cross section with a length (L) and a width (W) wherein the dimension of L is greater than the dimension of W. The filter can be used with an improved ink jet printhead having an ink inlet in one of its surfaces, a plurality of nozzles, individual channels connecting the nozzles to an internal ink supplying manifold, the manifold being supplied ink through the ink inlet, and selectively addressable heating elements for expelling ink droplets, the improved ink jet printhead comprising a substantially flat filter having predetermined dimensions and being bonded to the printhead containing the ink inlet, the filter having a plurality of pores, therethrough, each of the pores having a cross section with a length=L and a width=W, wherein the dimension of L is greater than the dimension of W. Also disclosed is a method for fabricating a filter element comprising the steps of positioning a thin polymer film in the output radiation path of an ablating laser, and controlling the laser output so that a plurality of pores are formed in portions of the polymer film, each of the pores having a cross section with a length (L) and a width (W), wherein the dimension of L is greater than the dimension of W.

摘要： A printhead uses large and small drop ejectors to achieve efficient gray scale printing. The printhead is arranged with a close packed configuration of alternating large and small nozzles positioned to maximize coverage while minimizing the volume of ejected ink. The printhead may be operated in a single pass mode or dual pass mode. In the single pass mode, complete coverage is effected by rippling through the odd numbered jets first and then rippling through the even numbered jets. The position of the small spots from the even numbered jets can be adjusted to maximize coverage and counteract offset between nozzle centers. Printheads with different size nozzles can also be operated by a staggered firing method using dual passes to offset spots in the scan direction by shifting the printhead between passes or alternating between groups of large and small nozzles. Further improvements to image quality can be realized by shifting the spots in the direction perpendicular to the scanning direction by tilting the printhead or offsetting the nozzles with respect to the ink channels on the printhead.

摘要翻译： 打印头使用大而小的墨滴喷射器来实现高效的灰度打印。 打印头布置成具有交替的大和小喷嘴的紧密堆积构造，其被定位成最大化覆盖范围，同时最小化喷射墨的体积。 打印头可以在单程模式或双通道模式下操作。 在单程模式中，完全覆盖通过首先通过奇数射流波纹，然后通过偶数喷射波纹来实现。 可以调整来自偶数喷嘴的小点的位置，以最大化覆盖范围并抵消喷嘴中心之间的偏移。 具有不同尺寸喷嘴的打印头也可以通过交错的点火方法来操作，使用双程通过在扫描方向上偏移打印头，使打印头在通过之间移动或在大喷嘴和小喷嘴组之间交替。 通过倾斜打印头或相对于打印头上的墨水通道偏移喷嘴，可以通过使垂直于扫描方向的方向上的点移动来实现对图像质量的进一步改进。

摘要： Individual printheads are joined together in a manner to provide improved alignment and registration. The multiple printhead assembly is then installed and removed from the printer as a single unit. According to a preferred method of forming the assembly, individual printheads are temporarily mounted on a holddown plate. The location and position of the printheads is monitored and a fast-cure adhesive used to monolithically join the individual printheads together as a unitary assembly. Once the adhesive is cured, the temporary securing of the individual printheads is removed and the entire assembly removed as a single unit from the holddown plate.

摘要： An ink-jet printer includes a printhead disposed on a reciprocating carriage. The printhead includes two sets of ejectors spaced by a predetermined pitch, in collinear linear arrays. The two sets of ejectors are offset by a partial pitch to enable interleaving of print swaths by the two sets of ejectors, in order to print at a higher resolution than the predetermined pitch would allow.

摘要： A thermal ink-jet printhead adapted to emit ink onto a print sheet is automatically adjusted. The printhead is caused to emit ink onto a sheet in a manner consistent with an image of a first density, and then substantially immediately caused to emit ink in the form of a first test pattern on the sheet. The density of the first test pattern on the sheet is measured. The printhead is caused to emit ink onto the sheet in a manner consistent with an image of a second density, and then substantially immediately caused to emit ink in the form of a second test pattern on the sheet. The density of the second test pattern on the sheet is measured. The densities of the first test pattern and the second test pattern are correlated with a function relating a characteristic of an image printed with the printhead to a temperature of the printhead.

摘要： An inkjet printhead having a drop ejector array, an ink passageway for providing ink to the drop ejector array, and a thermally actuated degassing unit. The degassing unit itself includes a body enclosing an air chamber, a check valve configured to allow air to vent from the air chamber to ambient when the pressure in the air chamber exceeds ambient air pressure by a predetermined amount. The thermal degassing unit includes a thermally-induced pressure build-up time to increase the pressure in the air chamber. The air chamber is allowed to cool which causes internal pressure to drop below ambient and draws gas out of the ink.
