ABSTRACT:
A multicolor liquid ink printer for printing unmottled, high quality images on sheets of plain paper. The multicolor liquid ink printer includes a flat, generally rectangular stationary platen having a first long side, a second long side, a first short end, a second short end, and a sheet supporting surface for supporting a sheet of plain paper. The multicolor liquid ink printer also includes a heating device for heating the stationary platen, and a sheet containing and feeding assembly for containing and feeding sheets of plain paper onto the sheet supporting surface of the stationary platen. Importantly, the multicolor liquid ink printer includes a bidirectionally movable sheet driving and printing assembly that is movable over and relative to the stationary platen and to a sheet being supported on the stationary platen. The sheet driving and printing assembly includes (i) a carriage; (ii) drive rollers mounted to the carriage for driving and moving a sheet on the stationary platen relative to the stationary platen, and (iii) a plurality of full width array printheads mounted to the carriage. Each full width array printhead of the plurality of full width array printheads contains a different color liquid ink for printing an unmottled, high quality liquid ink image onto a sheet of plain paper that is stationarily supported on the flat platen, thereby together forming an unmottled, high quality multicolor liquid ink image on the plain paper.
