Abstract
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.
