Ink pen assembly

摘要

An ink pen assembly (10) of a continuous ink jet printer includes a printhead nest and an ink pen cartridge (14) removably received within the nest. The cartridge includes a pen body (30) in electrical communication with the printhead nest, and a nozzle body (40) in fluid communication with the printhead nest. A charge electrode charges ink drops breaking off from ink jetted from an outlet of the nozzle body. A deflection electrode deflects the charged ink drops along an axis substantially transverse to a direction of travel of a substrate being printed. An ink block mount includes an ink blocking element for diverting deflected ink drops. An ink block actuator pivots with respect to the pen body to adjust the position of the ink blocking element. The printhead nest defines at least four ink outlets for delivering different colored inks, and at least four ink pen cartridges are removably received by the printhead nest. <IMAGE>
