Statement of Volatility
Your printer contains various types of memory that can store printer and network settings and user data.
Type of memory Description
Volatile memory Your printer uses standard random access memory
(RAM) to buer user data temporarily during simple print
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, printer settings, network
information and bookmark settings, and embedded
solutions.
Hard disk memory Some printers have a hard disk drive installed. The printer
hard disk is designed for printer-specific functionality.
The hard disk lets the printer retain buered user data
from complex print jobs, 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, extra steps are needed to make sure that
confidential
data stored in the printer
hard disk cannot be accessed. This precaution is necessary 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 are completely
erased is to destroy physically each hard disk where data is stored.
