ROCHESTER, N.Y., - Xerox Corporation (NYSE: XRX) announced today that it has been chosen to provide major printer upgrades at more than 30 Automatic Data Processing, Inc. (ADP®) payroll locations across the United States. The technology improvements are expected to increase ADP's ability to process and print payroll checks for the more than 29 million wage earners it serves worldwide each payday. Under the seven-year, $17 million contract, Xerox will provide service and support and upgrade existing Xerox equipment with 110 newer, faster and more cost-effective Xerox DocuPrint 180 MX Laser Printing Systems. The DocuPrint 180 MX printer, at speeds up to 180 pages per minute, allows ADP to print paychecks up to 30 percent faster than before. The DocuPrint 180 MX uses Magnetic Ink Character Recognition (MICR) technology to create the highest quality checks with a 99.9 percent read rate - which is measured by the rate of checks printed that can be accurately read by a bank reader/sorter unit. "The Xerox DocuPrint technology helps ADP deliver world-class service solutions to our extensive customer base," said Gary Butler, president and chief operating officer, ADP. "Using Xerox's advanced technology, we're able to print paychecks faster and decrease our processing time, while increasing operational effectiveness and accuracy to benefit our customers." In addition, Xerox is supporting ADP's Internet strategy with technology that helps shift payroll processing and management of payroll-data documents to the Web. The DocuPrint 180 MX technology will allow ADP the flexibility to direct payroll data it receives over the Internet to the Xerox printer fleet, via its network, while still processing other payroll through the mainframe, further increasing ADP's efficiency. "The companies have been working together since 1988, and this renewed association reaffirms ADP's confidence in Xerox technology, service and support," said Mike MacDonald, president, Xerox North American Solutions Group. ADP (NYSE: ADP), with more than $6 billion in revenue and 500,000 clients, is one of the largest independent computing services firms in the world. ADP Employer Services provides payroll services, human resource information systems and benefits administration to 450,000 employers worldwide.
