Glossary Double Letter size A standard paper size used in the United States and other countries (11 × 17 in.). dpi (dots per inch) A measurement of resolution which is used for scanners and printers. Higher dpi indicates better resolution. Driver A program specifically designed for operating systems, which enables interaction with a hardware device. Dropout color A function which removes a specified color from a scanned image. Duplex scanning mode A mode for scanning both sides of the document at once. (Ù simplex scanning mode) E Edge Extract A function which traces the boundaries between black and white areas, and extracts them as outlines. Edge Processing A function which decreases the density of bright colors (except for white) around black areas. Increasing the value for this function removes dotted image noise and also produces "softened" images. Eject roller Rollers that feed documents from the ADF onto the stacker. Energy Star ENERGY STAR is an international standard for energy-efficient electronic equipment which was established by the US Environmental Protection Agency (EPA) in 1992. The standard program has now been adopted by countries around the world. Error diffusion Method of halftone (pseudo-grayscale) image processing which is based on black & white pixel binarization. It sums the optical density of a pixel and its adjacent pixels, then relocates black pixels in the order of density to minimize the difference between scanned and output images. By diffusing the errors onto other pixels, the density data of adjacent pixels can be binarized. This function suppresses moire patterns of dotted halftone images such as newspapers, and reproduces its grayscale gradation.
