Watch how the Xerox ColorQube(TM) delivers 150 million ink drops per second through microscopic nozzles - half the width of a human hair. Don Titterington, vice president, print head and ink research and development at Xerox, explains how the heart of the ColorQube 9200 series is a print head that increases ink flow by 400%, through more than 3,500 nozzles.

Xerox's innovative print head and solid ink sticks combine to create the world's first high-speed solid ink office printer - the newly announced Xerox ColorQube(TM) 9200 Series. The print head, about the size of deck of cards, packs in 880 nozzles - twice the number per linear inch compared to prior print heads - enabling molten solid ink to print 85 pages per minute. Development of the miniscule nozzles (each only 37.5 microns wide) is considered a major achievement because they deliver higher flow rates - 150 million drops of ink per second -- despite their reduced size.
