Glossary 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 High-quality halftone (pseudo-grayscale) image processing based on black-and-white pixel binarization. A pixel's optical density and that of adjacent pixels are summed, with black pixels relocated in their order of density as they relate to adjacent pixels. The purpose of this technique is to minimize the average error between scanned and printed densities. Density data for adjacent pixels is modified by diffusing errors on the objective pixel into several pixels, which are then binarized. This maintains high grayscale levels and resolution during scanning, while suppressing more patterns by dotted halftone images such as newspaper photographs. F FCC Acronym for "The Federal Communications Commission", an independent United States government agency which is in charge of regulating interstate and international communications via radio, television, wire, satellite and cable. The Part 15 of the FCC regulations mentioned in this manual is designed to prevent harmful interferences on radio communication of radio receivers and other devices which radiate radio frequency energy, and provides for the certification of radio receivers. It also provides the certification of low power transmitters and the operation of certificated transmitters without a license. Feed roller Rollers that feed documents through the ADF. Filter Refers to the following types of processing on scanned images. Digital Endorser: Adds character strings such as alphabets and numbers to the scanned image data. Page Edge Filler: Fills in the margin area around the scanned image with a specified color.
