Statement of Volatility
Your printer contains various types of memory that can store device and network settings, and user data.
Types of memory Description
Volatile memory Your printer uses standard Random Access Memory
(RAM) to temporarily buer user data during simple print
and copy jobs.
Non-volatile memory Your printer may use 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 printers have a hard disk drive installed. The printer
hard disk is designed for device-specific functionality.
This lets the device retain buered user data from
complex scan, print, copy, and fax jobs, as well as form
data, and font data.
Erase the content of any installed printer memory in the following circumstances:
• The printer is being decommissioned.
• The printer hard disk 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 printer hard disk
Note: Some printer models may not have a printer hard disk installed.
In high‑security environments, it may be necessary to take additional steps to make sure that confidential data
stored in the printer hard disk cannot be accessed when the printer—or its hard disk—is removed from your
premises.
• Degaussing—Flushes the hard disk 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: Most data can be erased electronically, but the only way to guarantee that all data is completely
erased is to physically destroy each hard disk where data is stored.
Erasing volatile memory
The volatile memory (RAM) installed in your printer requires a power source to retain information. To erase the
buered
data, simply turn
o
the printer.
