Double Letter size
A standard paper size used in the United States and other countries (17 × 11 in.).
dpi (dots per inch)
A measurement of resolution that is used for scanners and printers. Higher dpi indicates better resolution.
Duplex scanning mode
A mode for scanning both sides of the document at once. (
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.
E
Edge Extract
A function that traces the boundaries between white and black areas to extract contours.
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.
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.
