Electrodes for a drop-on demand printer

摘要

The invention provides a drop-on-demand printer having a row of ink ejection locations for ejecting plural ink droplets, each ejection location having an associated ejection electrode for causing electrostatic ejection of the droplets from the respective ejection location. An intermediate electrode system has one or more rows of intermediate electrodes 3 spaced from the ejection locations between the ejection locations and a substrate on to which the droplets are printed during use. Plural conductive tracks 5 are provided, each corresponding to a respective intermediate or ejection electrode 3 and supplying a voltage to an electrode in use. Tracks 5 have a resistive element 14 either disposed immediately adjacent the corresponding electrode or actually forming the electrode 3.
