Abstract:
1. An ink jet printhead assembly that comprises a chassis; an ink distribution assembly that is mounted on the chassis, the ink distribution assembly being connectable to at least one supply of ink and defining a number of converging ink distribution conduits that terminate at elongate chip slots; a number of printhead chips mounted in respective chip slots so that inlets of each chip are in fluid communication with respective ink distribution conduits; a rotatable, multi-purpose platen assembly that is mounted on the chassis, in spaced relationship with respect to the printhead chips, the platen assembly including at least a platen surface for supporting sheets of print media fed between the platen assembly and the printhead chips and being linearly displaceable with respect to the printhead chips in a direction orthogonal to the platen surface in order to control the separation between the printhead chips and print media disposed on the platen during a print operation; and a print media feed mechanism for feeding the sheets of print media between the platen assembly and the printhead chips.
