Securing the hard disk and other installed

memory

Statement of Volatility

Your printer contains various types of memory that are capable of storing device and network settings,

information from embedded solutions, and user data. The types of memory—along with the types of data stored

by each—are described below.

• Volatile memory—Your device utilizes standard Random Access Memory (RAM) to temporarily buer user

data during simple print and copy jobs.

• Non‑volatile memory—Your device may utilize two forms of non-volatile memory: EEPROM and NAND (ﬂash

memory). Both types are used to store the operating system, device settings, network information, scanner

and bookmark settings, and embedded solutions.

• Hard disk memory—Some devices have a hard disk drive installed. The printer hard disk is designed for

device‑speciﬁc functionality and cannot be used for long term storage for data that is not print‑related. The

hard disk does not provide the capability for users to extract information, create folders, create disk or

network ﬁle shares, or FTP information directly from a client device. The hard disk can retain buered user

data from complex scan, print, copy, and fax jobs, as well as form data, and font data.

There are several circumstances under which you might wish to erase the contents of the memory devices

installed in your printer. A partial list includes:

• The printer is being decommissioned

• The printer hard drive is being replaced

• The printer is being moved to a dierent department or location

• The printer is being serviced by someone from outside your organization

• The printer is being removed from your premises for service

• The printer is being sold to another organization

Disposing of a hard drive

Note: Not all printers have a hard disk installed.

In high‑security environments, it may be necessary to take additional steps to ensure that

conﬁdential

data

stored on the printer hard disk cannot be accessed once the printer—or its hard disk—is removed from your

premises. While most data can be erased electronically, you may want to consider one or more of the following

actions before disposing of a printer or hard disk:

• Degaussing—Flushes the hard drive with a magnetic

ﬁeld

that erases stored data

• Crushing—Physically compresses the hard disk to break component parts and render them unreadable

• Milling—Physically shreds the hard disk into small metal bits

Note: While most data can be erased electronically, the only way to guarantee that all data is completely

erased is to physically destroy each memory device on which data could have been stored.
