System Overview
The system is divided into two main components: the Image Input Terminal (IIT - Document
Feeder/Scanner) and the Image Output Terminal (IOT - Print Engine).
Figure 1 Main System Components
This section covers the basic theory of operation for all major assemblies and subassembly
interactions for this system. This section is broken down into the following:
• The Image Input Terminal (IIT)
– DADF and paper path
– The Scanner Assembly with Control Panel
• System Electronics
– Electronics Module
– Scanner Power Supply
– Exit Module Control Board
• The Image Output Terminal
– Paper Path
– Sensing
– Drive
– Image Process
– Exit
Image Input Terminal
The IIT generates the image data for copies and scans and is made up of two major sub-
systems:
• Duplex Automatic Document Feeder (DADF)
• Scanner Assembly with Control Panel
