Breakthrough Scanning Technology Developed for DocuTech

Faster Speed or Better Quality? Xerox Innovates to Deliver Both
Professional document image scanners traditionally offer speed or quality - not both.
Much as cameras suffer image degradation at faster shutter speeds and lower light levels,
scanners require certain amounts of time and light to optimize image quality. Until Xerox
innovators came along, that meant that high-speed scanners could capture as many as 160
pages per minute (ppm), but would top out at 60 ppm for the 600 dots-per-inch (dpi)
resolution required in high-quality publishing applications.
Xerox Corporation engineers and scientists knew it was important to break that barrier if
digital printing was to replace offset in many applications. So they scrutinized the
scanner to find a way to provide both speed and quality. The result: a new system that
doubled the speed of 600-dpi scanning to 120 ppm. Independent observers say it establishes
a new image-quality benchmark.
First deployed at the beginning of 2004 as the integrated scanner in the new Xerox
DocuTech 100 and 120 Copier/Printers, it delivers the fastest speed and the best image
quality ever on this class of product. In addition, these are the first copier/printers
in their class to employ dual-scan heads for simultaneous scanning of the front and back
sides of a page, delivering the world's fastest high-quality, two-sided scanning (120
impressions per minute).
Advances in electronics, mechanics and software all played a role in the scanning
breakthrough. Among the most significant innovations: the Xerox patented silicon-based,
FWA (full-width array) image sensors. Image sensors on traditional scanners require
magnification and other intermediary processing, but the innovative Xerox technology
captures the full width of the page at full size as it passes by, eliminating the need for
magnification and much processing.
It also captures more light than other sensors, boosting speed and quality. In addition,
new Xenon gas illuminators replace traditional mercury to deliver immediate warm up,
superior image uniformity, greater stability and greater environment friendliness.
Innovative paper handling systems also play a critical role. Where most automatic
document handlers have a single actively driven feed roller, the Xerox system has two,
improving reliability and media latitude. "Side fluffers" which actively respond to paper
weight, blow air on paper stacks to separate the sheets and reduce multi-feeds and jams.
A wide turning radius and simple paper path enable an extensive range of paper sizes and
weights. Additional rollers on the glass platen - one in front of each scan head and one
behind - keep paper flat against the platen and provide tight control of paper transport
speed. And a 300-sheet capacity input tray for big jobs and the ability to handle
mixed-size originals help maximize productivity. The result: a breakthrough scanning
system that finally eliminates the need to choose between speed and quality.
