Abstract: Provided is an image forming apparatus that eliminates the necessity for resetting a single-sided document even if a set error of the single-sided document is occurred. The automatic document feeder includes a switchback mechanism that inverts the front and back of the single-sided document to switch a surface of the single-sided document.

Abstract: An example embodiment may involve obtaining an a×b pixel macro-cell from an input image. Pixels in the a×b pixel macro-cell may have respective pixel values and may be associated with respective tags. It may be determined whether at least e of the respective tags indicate that their associated pixels represent edges in the input image. Based on this determination, either a first encoding or a second encoding of the a×b pixel macro-cell may be selected. The first encoding may weigh pixels that represent edges in the input image heavier than pixels that do not represent edges in the input image, and the second encoding might not consider whether pixels represent edges. The selected encoding may be performed and written to a computer-readable output medium.
