Modular ink jet printhead assembly with obliquely overlapping printheads

摘要

A modular printhead assembly includes an elongate chassis. A plurality of elongate printhead modules is serially arranged along and engaged with the chassis. Each end of each printhead module is shaped so that each adjacent pair of printhead modules forms a complementary fit. Each printhead module includes an elongate printhead configured to eject ink. Each printhead is oriented obliquely with respect to the longitudinal axis of the chassis. Each adjacent pair of printheads overlaps to enable continuous printing along the axis.
