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
• Operational summaries
• Data flow
• Data security considerations

• Serial communication between the external charge device I/F and external coin/card-operated
devices
• External controller I/F board: Acts as the interface between the MFP and external controller
• File Format Converter: Converts the file format of image files
• RC Gate: Intermediary device connected to the MFP/LP via an Ethernet connection for performing
remote diagnostic operations including firmware updates and settings changes
• SD card I/F: Used for performing service maintenance and as an interface for firmware storage media
• RAM, HDD: Image data stored in the RAM and HDD memory undergoes compression, decompression
and other image processing
• HDD storage: Data stored on the HDD is encrypted
• TPM (Trusted Platform Module): When the MFP/LP main power is turned on, this security module
(chip) performs a verification on the validity of the software installed on the hardware platform, which
includes checking for any illegal alterations
