摘要： A large array or pagewidth printhead fabricated from printhead elements or subunits. The printhead subunits are butted together at either adjacent channel elements or adjacent heater elements to form a pagewidth printhead. The butting element, either heater or channel element, is slightly wider than the non-butting element thereby providing gaps between the non-butting elements of a printhead element array. Where channel elements are used as the butting element, gaps between the heater elements provide for reduction or elimination of potentially damaging thermal compressive forces between adjacent heater elements. Where heater elements are used as the butting element, structural strength is increased since the heater wafer is stronger than the channel wafer. In addition, the width of the polyimide wall at the edges of the heater wafer is increased providing greater protection for thermal transducers located at the edges of individual heater elements.

摘要翻译： 由打印头元件或子单元制造的大阵列或页宽打印头。 打印头子单元在相邻的通道元件或相邻的加热器元件对接在一起以形成页宽打印头。 对接元件（加热器或通道元件）比非对接元件稍宽，从而在打印头元件阵列的非对接元件之间提供间隙。 在使用通道元件作为对接元件的情况下，加热器元件之间的间隙用于减少或消除相邻加热器元件之间潜在的有害的热压缩力。 当加热器元件用作对接元件时，由于加热器晶片比通道晶片更强，所以结构强度增加。 此外，加热器晶片边缘处的聚酰亚胺壁的宽度增加，为位于各个加热器元件边缘的热传感器提供更大的保护。

摘要： A method for assembling a printhead such as an ink jet printhead can include the use of a laser to bond two or more printhead layers together. In an embodiment, a laser beam is directed through a transparent layer to an energy-absorbing layer, where the energy-absorbing layer is melted such that after removal of the laser beam the melted layer solidifies to adhere the energy-absorbing layer to the transparent layer. In another embodiment, heating the energy-absorbing layer melts the transparent layer to adhere the energy-absorbing layer to the transparent layer after removal of the laser beam. The laser transmission lamination process described can result in a fluid-tight seal which requires less processing time and materials over an adhesive-based process.

摘要： A method and structure for an ink jet printhead, and a printer including the ink jet printhead. The printhead can include a polymer as a film spacer which separates an electrical interconnect such as a printed circuit board or a flexible circuit from a printhead diaphragm, such that the film spacer is interposed between the electrical interconnect and the diaphragm. In an embodiment, a piezoelectric actuator is free from contact with the film spacer. Embodiments of a process for forming the printhead may have reduced processing stages requiring fewer manufacturing tools than some other processes. Embodiments of the resulting printhead and printer may have fewer structural components than some other printheads and printers.

摘要： A method and structure for forming an ink jet print head having a dielectric interstitial layer. A flexible top plate attached to a press can be used to apply pressure to an uncured dielectric interstitial layer. The uncured dielectric interstitial layer is cured while contacting the uncured dielectric interstitial layer with the flexible top plate and applying pressure using the press. Using a flexible top plate rather than a rigid top plate has been found to form a cured interstitial layer over an array of piezoelectric elements which has a more uniform or planar upper surface. An interstitial layer so formed can result in decreased processing time, reduced problems with ink communication in the ink jet print head during use, and decreased manufacturing costs.

摘要： System and method for encapsulating edges of a paper in digital printing systems. A spray applicator can include a set of stationary sprayers with spray nozzles, a set of transfer rollers and an inkjet print head. The stationary sprayers can be positioned at both marginal ends of the paper. The stationary sprayers apply the fluid through the spray nozzles at edges of the moving paper to encapsulate the edges of the paper such that loose paper fibers and debris are bound to the paper. The fluid can be applied when the transfer rollers can pass the moving paper through a printer or printing press. Thus, the system can protect various subsystems of the printer or printing press against contamination due to the loose paper fibers and debris.
