Printer having printhead assembly with constrained nozzles

摘要

A printer is provided having a removably mounted printhead assembly. The printhead assembly has at least one printhead module having at least two printhead integrated circuits, each of which has nozzles formed therein for delivering printing fluid onto the surface of print media, and a support member supporting and carrying the printing fluid for the at least two printhead integrated circuits; and an elongate casing in which the at least one printhead module is removably mounted so as to constrain movement of the at least one printhead module relative to the casing in at least the direction of printing fluid delivery from the nozzles to the print media whilst allowing movement of the at least one printhead module in the longitudinal direction of the casing.
