Abstract
A staggered array printhead, recording medium support and capping and/or maintenance assembly for use in an ink jet printer is described. Capping and maintenance of printhead sub-units of the staggered array is performed by self-positioning and aligning members located on a capping and/or maintenance member which is movably positioned on one side of a recording medium support. The printhead is located on an opposite side of the recording medium support, staggered openings being provided in the support to enable contact between the capping and/or maintenance members and front faces of the printhead subunits. Heat management of the printhead is provided by an ink manifold positioned over the printhead subunits. The manifold includes fingered portions which extend into spaces between the subunits. Assembly of a staggered array printhead is facilitated by the use of a high precision fixture having recesses for the receipt of printhead subunits.
