Ricoh Aficio Common Security Features Guide
RAM-based Security
Several low-end digital systems use RAM (Random Access Memory) for document processing tasks, not
a hard disk drive. Though a hard drive may be available as an option, there is security benefit to non-
HDD equipped systems in that jobs processed through RAM are volatile. This means that when power to
the system is turned off, all temporary print data is immediately erased. Without a means to permanent-
ly store data, such as a hard drive, the security threat of unauthorized reprinting is eliminated. As such,
RAM-only devices can be proposed for environments where information security is the top priority.
Removable Hard Disk Drive
Several Ricoh high volume MFPs offer the Removable
Hard Drive option for ultra-security conscious
customers. The Removable Hard Drive (RHD) option
provides an ideal security solution for government,
military, and other office environments that require
high security. The system's internal hard drive is
externally mounted in a secure bay, allowing the hard
drive to be unlocked, removed and stored in a secure
external location. To add an extra layer of security, an
additional removable hard drive may be purchased to
keep classified and unclassified information separate.
Unauthorized Copy Control/Masked Type
This function discourages the illegal copying of
documents that were originally created and
printed using the RPCS driver. When the optional
Copy Data Security Unit is installed, files printed
via the RPCS driver can be embedded with
a special message that instructs the scanners of
other Ricoh devices not to copy, scan, or send
the page. Instead, page content is either grayed
out, or overprinted with one of 10 possible
obscuring patterns and/or a customized text
message to deter illegal copying.
