摘要： A printhead includes a liquid manifold. A filter is in fluid communication with the liquid manifold. A nozzle plate includes a length and an array of nozzles extending along the length of the nozzle plate. A liquid chamber is positioned between the nozzle plate and the filter. The liquid chamber is in fluid communication with the array of nozzles and the filter and includes a width that is substantially perpendicular to the length of the nozzle plate. The liquid chamber includes a structure that is spaced apart from the nozzle plate and spaced apart from the filter. The structure spans the width of the liquid chamber. A liquid source provides a liquid through the manifold, the filter, the liquid chamber under pressure sufficient to jet individual streams of the liquid from the array of nozzles.

摘要： A printhead includes a liquid manifold. A filter is in fluid communication with the liquid manifold. A nozzle plate includes a length and an array of nozzles extending along the length of the nozzle plate. A liquid chamber is positioned between the nozzle plate and the filter. The liquid chamber is in fluid communication with the array of nozzles and the filter and includes a width that is substantially perpendicular to the length of the nozzle plate. The liquid chamber includes a structure that is spaced apart from the nozzle plate and in contact with the filter. The structure spans the width of the liquid chamber and includes a plurality of flow through channels. A liquid source provides a liquid through the manifold, the filter, the liquid chamber under pressure sufficient to jet individual streams of the liquid from the array of nozzles.

摘要： A catcher design is provided wherein vacuum channels are added to both sides of the catcher to remove ink from the face of the catcher and from the eyelid seal. An additional fluid port on the catcher allows the additional vacuum channels to maintain an increased level of vacuum. A restriction on the catcher line balances the fluid flow between the catcher and the additional vacuum channels. A scoop can be machined into the catch pan to remove fluid from below the catcher face. A manifold can be used to maintain a vacuum source for the catcher throat and the additional channels, while pulling the unprinted ink back to the fluid system. Finally, a wider eyelid seal can allow purge fluid used during shutdown to clear the channels.
摘要翻译： 提供捕手设计，其中真空通道被添加到捕集器的两侧以从捕获器的表面和眼睑密封件中去除墨水。 捕集器上的另外的流体端口允许附加的真空通道保持增加的真空度。 对捕集线的限制平衡了捕手和附加真空通道之间的流体流动。 勺子可以加工到捕集盘中以从捕获器表面下方排出流体。 可以使用歧管来保持捕集器喉部和附加通道的真空源，同时将未打印的墨水拉回流体系统。 最后，更宽的眼睑密封件可以允许关闭期间使用的清洗液清除通道。

摘要： A printhead includes a jetting module that forms drops, a catcher, and a deflection mechanism that deflects some of the drops toward the catcher. A moveable sealing mechanism has a first position in contact with the catcher and a second position removed from the catcher that permits drops to travel past the catcher. The moveable sealing mechanism includes a first portion that is fixed to the printhead and translates the sealing mechanism relative to the catcher, and a second portion that is removably fixed to the first portion and cooperates with the catcher to form a seal when the sealing mechanism is in the first position. A removal tool for use with the printhead includes a shaft, a magnet affixed to the shaft, and a spacer affixed to the shaft. The spacer includes a valley that is aligned with the at least one magnet.
