Securing the printer 144 Notes: • To avoid loss of data, do not turn off the printer during the encryption process. • This process can take from several minutes to more than an hour, making the printer unavailable for other tasks. • After encryption, the printer automatically restarts. Restoring factory default settings From the home screen, touch Settings > Device > Restore Factory Defaults > Restore Settings > Restore all settings > RESTORE > Start. For more information, see "Erasing printer memory" on page 143. Statement of Volatility Type of memory Description Volatile memory The printer uses standard random access memory (RAM) to buffer temporarily user data during simple print and copy jobs. Non-volatile memory The 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, scanner and bookmark settings, and embedded solutions. Hard disk memory Some printers may have a hard disk drive installed. The printer hard disk is designed for printer-specific functionality. The hard disk lets the printer retain buffered 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 decommissioned. • The printer hard disk is replaced. • The printer is moved to a different department or location. • The printer is serviced by someone from outside your organization. • The printer is removed from your premises for service. • The printer is sold to another organization. Disposing of a printer hard disk • 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: To guarantee that all data are completely erased, destroy physically each hard disk where data is stored.

Statement of Volatility
Type of memory
Description
Volatile memory
The printer uses standard random access memory (RAM)
to buffer temporarily user data during simple print and
copy jobs.
Non-volatile memory
The 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, scanner and bookmark settings, and
embedded solutions.
Hard disk memory
Some printers may have a hard disk drive installed. The
printer hard disk is designed for printer-specific
functionality. The hard disk lets the printer retain buffered
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 decommissioned.
The printer hard disk is replaced.
The printer is moved to a different department or location.
The printer is serviced by someone from outside your organization.
The printer is removed from your premises for service.
The printer is sold to another organization.
Disposing of a printer hard disk
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:
To guarantee that all data are completely erased, destroy physically each hard disk where data is
stored.
