    • A method of monitoring gaseous accumulation within an ink flow path in fluid communication with a printhead comprising: (a) supplying a first printhead with ink using a first ink flow path; (b) mounting a first ink filter in fluid communication with the first printhead; and (c) sensing downstream from the first ink filter for gaseous components within the first ink flow path. In addition, the invention provides a printing device comprising: (a) a first printhead that includes a first set of nozzles, a first ink filter, and a first conduit between the first ink filter and the first set of nozzles for delivering filtered ink to the first set of nozzles; and (b) a sensor operative to detect at least one of bubble formation and bubble growth within the first conduit.
    • 一种监测与打印头流体连通的油墨流动路径中的气体积聚的方法,包括:(a)使用第一墨水流路向第一打印头供应墨水; (b)安装与第一打印头流体连通的第一墨水过滤器; 和(c)从第一墨水过滤器的下游感测第一墨水流动路径内的气体成分。 另外,本发明提供了一种打印装置,包括:(a)第一打印头,其包括第一组喷嘴,第一墨水过滤器和第一墨水过滤器与第一组喷嘴之间的第一导管,用于将过滤的墨水输送到 第一套喷嘴; 和(b)可操作以检测第一导管内的气泡形成和气泡生长中的至少一个的传感器。
