Overview

This document describes the structural layout and functional operations of the hardware and software for

the multi-functional products and laser printers listed below (herein referred to as the “MFP” and “LP”,

respectively), which were designed and developed by Ricoh Co. Ltd. (herein referred to as Ricoh), as well

as the information security of image data and other information handled internally by Ricoh MFP/LPs.

The explanations will primarily focus on the following, with particular attention to demonstrating how

unauthorized access is not possible to local network environments via FAX telecommunications lines, nor

to any of the data stored in the MFP/LP.
