摘要： A system includes a print head including multiple nozzles formed in a bottom surface of the print head. The nozzles are configured to eject a liquid onto a substrate. The system includes a gas flow module configured to provide a flow of gas through a gap between the bottom surface of the print head and the substrate. The gas flow module can include one or more gas nozzles configured to inject gas into the gap. The gas flow module can be configured to apply a suction to the gap.

摘要： An apparatus includes an inkjet assembly having inkjet nozzles through each of which ink flows at a nominal flow rate as it is ejected from the nozzle onto a substrate. Ink is held under a nominal negative pressure associated with a characteristic of a meniscus of the ink in the nozzle when ejection of ink from the nozzle is not occurring. The apparatus includes recirculation flow paths, each flow path having a nozzle end at which it opens into one of the nozzles and another location spaced from the nozzle end that is to be subjected to a recirculation pressure lower than the nominal negative pressure so that ink is recirculated from the nozzle through the flow path at a recirculation flow rate. Each recirculation flow path has a fluidic resistance between the nozzle end and the other location such that a recirculation pressure at the nozzle end of the flow path that results from the recirculation pressure applied at the other location of the flow path is small enough so that any reduction in flow rate below the nominal flow rate when ink is being ejected is less than a threshold, or a change in the nominal negative pressure when ink is not being ejected is less than a threshold, or both.
摘要翻译：一种设备包括具有喷墨喷嘴的喷墨组件，当喷嘴从喷嘴喷射到基板上时，墨水以标称流速流动。当没有发生从喷嘴喷射墨水时，墨水保持在与喷嘴中的墨水的弯月面的特性相关的标称负压下。该设备包括再循环流动路径，每个流动路径具有喷嘴端部，在喷嘴端部处，其通向一个喷嘴，并且与喷嘴端部隔开的另一个位置将经受比标称负压低的再循环压力，使得墨水以再循环流量从喷嘴通过流路再循环。每个再循环流动路径在喷嘴端与另一个位置之间具有流体阻力，使得由在流动路径的另一个位置处施加的再循环压力引起的流动路径的喷嘴端处的再循环压力足够小，使得任何当墨水喷射时低于标称流量的流量减小小于阈值，或者当墨未被喷射时标称负压的变化小于阈值或两者。
