Abstract
A method of cleaning an electrostatic printhead which has one or more ejection tips from which, in use, ink is ejected, the method comprising: stopping a prior flow of ink to a region around the ejection tip(s) for, in use, printing; causing a pressure differential to occur at the tip region thereby causing the ink meniscus to retreat from the tip; and passing a rinse into the tip region to clean the tip.
