Securing data 51 4 Select one of the following: • Erase Memory-Erase all settings, applications, and job data. • Erase Memory and Hard Disk (Single Pass)-Erase all settings, applications, and job data (including all the contents of the hard disk) in a single pass with a repeating bit pattern. • Erase Memory and Hard Disk (Multiple Pass)-Erase all settings, applications, and job data (including all contents of the hard disk) with random bit patterns several times, followed by a verification pass. A secure erase is compliant with the DoD 5220.22‑M standard for securely erasing data from a hard disk. Highly confidential information should be erased using this method. 5 Follow the instructions on the printer display. Warning-Potential Damage: Do not turn off the printer while erasing data. This process may take several hours to complete. 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 as follows: • Volatile memory-Your device utilizes standard random access memory (RAM) to temporarily buffer 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 buffered user data from complex scan, print, copy, and fax jobs, as well as form data, and font data. You may want to erase the contents of the memory devices installed in your printer when: • The printer is being decommissioned. • The printer hard drive is being replaced. • The printer is being moved to a different department or location. • The printer is being serviced by someone from outside your organization. • The printer is being removed from your premises for service. Disposing of a hard disk Note: Some printer models may not have a hard disk installed. High‑security environments may require additional steps to ensure that confidential data on the printer or hard disk cannot be accessed when either is removed from premises. • 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: Most data can be erased electronically, but to guarantee that all data is completely erased, physically destroy each hard disk where data is stored.

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 as follows:
•
Volatile memory
—Your device utilizes standard random access memory (RAM) to temporarily buffer 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 buffered user
data from complex scan, print, copy, and fax jobs, as well as form data, and font data.
You may want to erase the contents of the memory devices installed in your printer when:
•
The printer is being decommissioned.
•
The printer hard drive is being replaced.
•
The printer is being moved to a different department or location.
•
The printer is being serviced by someone from outside your organization.
•
The printer is being removed from your premises for service.
Disposing of a hard disk
Note:
Some printer models may not have a hard disk installed.
High
‑
security environments may require additional steps to ensure that confidential data on the printer or hard
disk cannot be accessed when either is removed from premises.
•
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:
Most data can be erased electronically, but to guarantee that all data is completely erased, physically
destroy each hard disk where data is stored.
