Abstract
A head (13) comprises a closed container (15) carrying internal (139) and external electrodes and a nozzle (18) and is mounted removably on a carriage (14) on which it is held by a permanent magnet (43) in such a way that the head bears with the external electrode against a metal sheet (32). The magnet is of an annular shape and is carried by the carriage. It attracts a metal plate (39) in the bottom of the container, which carries a pin (41) for centering the head on the carriage and is utilized to make connection to the internal electrode (139). A protuberance adjacent the nozzle (18) presses against the metal sheet (32) which in turn presses the paper (11) against a platen (10). The protuberance establishes the jet-to-paper spacing.
