Resistively coated deflection ribbon for an ink jet printing device

摘要

A conductive deflection ribbon (52) is provided in an ink jet printing device (10) in which the ribbon (100) is coated with a highly resistive material (101). The deflection ribbon (52) is positioned adjacent a row of orifices (26) in an orifice plate (18) from which are expelled series of droplets (84). Selected ones of the droplets (84) are charged in such a manner they are deflected towards a catching device (54) by an electrostatic field established between the deflection ribbon (52) and the catching device (54). The resistive coating (101) inhibits the production of shorts between the charge plate (50), orifice plate (18) catcher (54) and the ribbon (52).
