K Service Source Basics Color OneScanner
Basics Overview - 1 Overview The Color OneScanner is a 24-bit one-pass flatbed scanner with a scanning resolution up to 1200 dpi. The Color OneScanner uses a tri-linear CCD to capture eight bits each of red, green, and blue in one pass. As a one-pass scanner, it samples all three colors at the same time, resulting in truer color and better registration than a scanner that makes separate passes for each primary color.
Basics Overview - 2 Features The Color OneScanner offers • Selectable 75- to 1200-dpi scanning resolution • Scanning of documents up to 8.
