摘要： In one embodiment, a non-contact print head cleaning device includes an elongated cavity underlying a print head and a vacuum port connected to the elongated cavity and generating a low pressure in the elongated cavity. A slot in a wall of the elongated cavity has a geometry that varies along its length to produce an airflow with a substantially uniform velocity into the slot. The airflow sucks contaminants off the print head into the slot. A method for non-contact print head cleaning is also provided.
摘要翻译：在一个实施例中，非接触式打印头清洁装置包括在打印头下方的细长空腔和连接到细长腔并且在细长空腔中产生低压的真空端口。细长腔的壁中的狭槽具有沿其长度变化的几何形状，以产生具有基本均匀的速度进入槽的气流。气流将污染物从打印头吸入槽中。还提供了一种用于非接触式打印头清洁的方法。

摘要： An apparatus includes a tank for holding a fluid for delivery to a printhead, the tank being open to the atmosphere. A manifold enables the fluid to flow from the tank to the printhead, a height of the manifold being lower than a level of the fluid in the tank when the fluid is flowing from the tank to the printhead. A siphon has a lower end of the siphon that is connectable to the manifold. An upper end of the siphon extends above the level of the fluid and is openable to the atmosphere. A height of a segment of the siphon between the upper end and the lower end is lower than the height of the manifold.
摘要翻译：一种装置包括用于保持用于输送到打印头的流体的罐，罐对大气开放。歧管使流体能够从罐流到打印头，当流体从罐流向打印头时，歧管的高度低于罐中流体的高度。虹吸管具有可与歧管连接的虹吸管的下端。虹吸管的上端在流体的水平面上方延伸，并且可以向大气敞开。上端和下端之间的虹吸段的高度低于歧管的高度。

摘要： In one embodiment, an actuator connected to a printhead structure is activated with a waveform to cause vibration of the structure sufficient to move fluid within a printhead channel adjacent to the structure and not cause the fluid to eject from the channel during a nonprinting period. In another embodiment, a first pulse module applies a pulse at a printhead structure at a combination of voltage, duration, and frequency to cause shaking of printhead structure to move fluid within a printhead channel adjacent to the structure without ejecting the fluid from the channel during a nonprinting period. In another embodiment, an actuator connected to a printhead structure is activated during a nonprinting period to pulse the structure to move fluid within a printhead channel adjacent to the structure without causing the fluid to be expelled from the channel.
摘要翻译：在一个实施例中，连接到打印头结构的致动器被激活，以使得结构的振动足以在与该结构相邻的打印头通道内移动流体，并且在非打印期间不使流体从通道喷出。在另一个实施例中，第一脉冲模块以电压，持续时间和频率的组合在打印头结构处施加脉冲，以引起打印头结构的抖动，以在与该结构相邻的打印头通道内移动流体，而不会在通道期间弹出流体非印刷期。在另一个实施例中，连接到打印头结构的致动器在非打印周期期间被激活以脉冲结构以在与结构相邻的打印头通道内移动流体，而不会使流体从通道排出。
