							Securing the memory before moving the printer
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 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.
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 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
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.
Erasing volatile memory
The volatile memory (RAM) installed on your printer requires a power source to retain information. To erase the
buffered data, simply power down the device. Securing the memory before moving the printer 212 
						

							Erasing non‑volatile memory
Individual settings, device and network settings, security settings, and embedded solutions—Erase information
and settings by selecting Wipe All Settings in the Configuration menu.
Fax data—Erase fax settings and data by selecting Wipe All Settings in the Configuration menu.
1Turn off the printer.
2Hold down  and 6MNO while turning the printer on. Release the buttons only when the screen with the progress
bar appears.
The printer performs a power-on sequence, and then the Configuration menu appears. When the printer is fully
powered up, the touch screen displays a list of functions, instead of the standard home screen icons.
3Touch Wipe All Settings.
The printer will reboot several times during this process.
Note: Wipe All Settings securely removes device settings, solutions, jobs, faxes, and passwords on the printer.
4Touch Back > Exit Config Menu.
The printer will power‑on reset, and then return to normal operating mode.
Erasing printer hard disk memory
Notes:
Some printer models may not have a printer hard disk installed.
Configuring Erase Temporary Data Files in the printer menus lets you remove residual confidential material left
by print jobs by securely overwriting files that have been marked for deletion.
Using the printer control panel
1Turn off the printer.
2Hold down 2 and 6 while turning the printer on. Release the buttons only when the screen with the progress bar
appears.
The printer performs a power-on sequence, and then the Configuration menu appears. When the printer is fully
turned on, the touch screen displays a list of functions.
3Touch Wipe Disk, and then touch one of the following:
Wipe disk (fast)—This lets you overwrite the disk with all zeroes in a single pass.
Wipe disk (secure)—This lets you overwrite the disk with random bit patterns several times, followed by a
verification pass. A secure overwrite is compliant with the DoD 5220.22‑M standard for securely erasing data
from a hard disk. Highly confidential information should be wiped using this method.
4Touch Yes to proceed with disk wiping.
Notes:
A status bar will indicate the progress of the disk wiping task.
Disk wiping can take from several minutes to more than an hour, during which the printer will be unavailable
for other user tasks.
5Touch Back > Exit Config Menu. Securing the memory before moving the printer 213 
						

							The printer will perform a power‑on reset, and then return to normal operating mode.
Configuring printer hard disk encryption
Note: Your printer may not have a hard disk installed.
Enabling hard disk encryption helps prevent the loss of sensitive data in the event your printer or its hard disk is stolen.
Using the Embedded Web Server
1From the Embedded Web Server, click Settings > Security > Disk Encryption.
Note: Disk Encryption appears in the Security Menu only when a formatted, non‑defective printer hard disk is
installed.
2From the Disk encryption menu, select Enable.
Notes:
Enabling disk encryption will erase the content of the printer hard disk.
Disk encryption can take from several minutes to more than an hour, during which the printer will be
unavailable for other user tasks.
3Click Submit.
Using the printer control panel
1Turn off the printer.
2Hold down  and 6MNO while turning the printer on. Release the buttons only when the screen with the progress
bar appears.
The printer performs a power-on sequence, and then the Configuration menu appears. Once the printer is fully
powered up, the touch screen displays a list of functions, instead of standard home screen icons such as Copy or
Fax.
3Touch Disk Encryption > Enable.
Note: Enabling disk encryption will erase the contents of the printer hard disk.
4Touch Yes to proceed with disk wiping.
A status bar will indicate the progress of the disk wiping task. After the disk has been encrypted, the printer will
return to the Enable/Disable screen.
Notes:
Do not turn off the printer during the encryption process. Doing so may result in loss of data.
Disk encryption can take from several minutes to more than an hour, during which the printer will be
unavailable for other user tasks.
5Touch Back, and then Exit Config Menu.
The printer will power‑on reset, and then return to normal operating mode. Securing the memory before moving the printer 214 
						

							Maintaining the printer

							Ordering supplies
To order supplies in the U.S., contact Lexmark at 1-800-539-6275 for information about Lexmark authorized supplies
dealers in your area. In other countries or regions, go to the Lexmark suport Web site at 
www.lexmark.com or contact
the place where you purchased the printer.
Notes:
The toner gauge is an estimate of how much toner is left in your cartridge.
All life estimates for printer supplies assume printing on letter‑ or A4‑size plain paper.
Ordering a print cartridge
When 88 [color] cartridge low or 88 [color] cartridge nearly low appears, order a new
cartridge.
Estimated cartridge yield is based on the ISO/IEC 19798 standard. Extremely low print coverage (less than 1.25%) for
extended periods of time may negatively affect actual yield and may cause cartridge parts to fail prior to exhaustion
of toner.
