SCX6220/6320F can be divided into the following main constituent parts: Main Controller, Operator's Panel, PC
Interface, Scanner, DADF, Line Interface and Power Supply. The Main Controller uses the SPGPm processor
which is common to many FAX and Printer products.

on a separate Network Interface card.
Each Part is designed with emphasis on Common-Use/Standardization with other models as independent
modules.
