A xerographic printing machine having the capability to output documents at a high resolution (600 spi) requires input documents of the same resolution, or a means for recognizing the lower resolution (300 spi) of the input document and modifying it to enable printing at the higher resolution. The figure illustrates the logical control algorithm used to implement the recognition and conversion of low resolution document images.
