Introduction
This service manual is to be used to service and maintain the 8830 DDS (Digital Document
System) and to provide direction as to the maintenance and service of the other elements resi-
dent within the 8830 Digital Document System.
The 8830 DDS is an Integrated solution for electronically scanning and printing images for
engineering or architectural use. Printing and Copying can be done concurrently in this system,
so there is no need to wait for the printer to finish printing before scanning the next image. The
system is comprised of the following elements:
• Xerox 7356 Scanner and the attached Xerox 8830 DDS Control Panel - for capturing
Images.
• Xerox 8830 Controller - for processing these images.
• Xerox 8830 Printer • for making good quality copies of the captured Images In engineer-
ing or architectural sizes.
• Xerox 8830 Folder • optional device for folding the printed images.
