摘要

A print engine assembly includes an elongate chassis; a pair of bearing moldings operatively mounted to either end of the chassis; a rotatable platen supported by a rotary shaft extending between and mounted in the pair of bearing moldings; and a printhead assembly mounted to the chassis, the printhead assembly including an elongated pagewidth printhead having a plurality of ink printing integrated circuits. The rotatable platen includes an extruded material shaped to define a cavity in which a blotting material is disposed, and the rotatable platen defines an aperture extending along a length thereof through which aperture the blotting material is exposed.
