There are two modes:

■

Mask Type for Copying is a standard RPCS feature that

embeds a masking pattern and/or message within the

original printout. If copies are made, an embedded

message or the document originator's name appears

on top of one of the selected masking patterns (shown

above). Users can design the message just as they

would a typical watermark.

■

Data Security for Copying produces a page in which

the entire image area is grayed out, making the

document illegible.

Commercial Facsimile Security Solutions

Facsimile is included in this Security Solutions review as it remains a viable communication technology

and Ricoh supports a complete line of stand-alone Super G3 laser fax solutions, as well as network fax

systems and fax board options that can be installed within MFPs.

Even though a standard G3 fax unit utilizes digital scanning and printing it uses a modem for

communication over a standard phone line. Since most standard phone lines are analog the modem

converts the digital data to a format that can be sent over the analog phone lines. The receiving

machine converts the analog data back to digital data so that the fax system can process and print it.

Therefore, fax has a different set of security features and customers have a different set of questions for

fax based solutions.

The most common question is whether a customer's data network can be penetrated via the fax

connection on stand-alone fax system, network fax system, or an MFP with fax capability. The answer is

NO. A Ricoh standalone fax, network fax or MFP with fax uses only a Class 1 modem that only controls

fax transmission/reception. Regardless if fax is part of a network fax or an MFP connected to a network,

the modem is physically separated from the main processor or any other network port. The fax modem

cannot accept or understand any PDL or device command stream other than those conforming to

established fax protocols, and therefore a data network cannot be breached via the fax modem.
