Abstract:
1. A removable printhead assembly for a printer which prints onto a moving web, comprising: a full width stationary printhead with an elongate casing; a rail mounted within the printer, the elongate casing and the rail having complementary external features extending longitudinally along each such that inserting the printhead into the printer requires an end of the elongate casing to engage an end of the rail via the complementary external features in order to slide along the rail into operative position within the printer; a number of replaceable ink reservoirs mounted in the printer, the replacable ink reservoirs being configured to supply the printhead with different inks; the printhead comprising a color printhead which is at least as wide as the web; and the printhead being supplied with the different inks through tubes which can be disconnected so the printhead may be removed by sliding longitudinally with respect to the rail until the complementary external features on the rail and the elongate casing disengage.
