  • Patent number: 6003969
    Abstract: A pixel matrix printer 10 scales a pixel input image into a dot matrix output image printed on paper 10R by selectively depositing discrete pixel toner units onto the paper. A toner source array 12A carried by mounting head 12H is responsive to the input image to selectively deposit the discrete toner units. The toner source array has N uniformly spaced toner sources extending along an array axis which forms a known cant relative to the advance direction. A pixel scanner mechanism provides a scanning relative motion between the toner source array and the paper along the scan direction. Each scan cycle forms a raster of N matrix rows as the toner units are deposited. Successive cycles form successive rasters in registration with the paper advance collectively forming the output image on paper 10R. A raster advance mechanism provides advance relative motion between the toner source array and the paper along the advance direction.
