Xerox says its new Acolor 620 colour copier offers versatility and speed and can print six colour pages or 24 black-and-white pages per minute. Paper sizes range from A6 to 12 inches by 18 inches, and paper types include coated, postcards, transparencies, tracing, plain and recycled. Adjustments can be made to sharpness, colour saturation, colour control and copy density and there are four pre-programmed colour schemes. The Acolor 620 uses 400 dpi resolution and 256 colour gradations. When connected to a PC the copier can also function as a colour laser printer or scanner.
