Erasing printer hard disk memory

Note: Some printer models may not have a printer hard disk installed.

Configuring Disk Wiping 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.

The printer will perform a power‑on reset, and then return to normal operating mode.

Configuring printer hard disk encryption

Enable hard disk encryption to prevent loss of sensitive data in the event the printer or its hard disk is stolen.

Note: Some printer models may not have a printer hard disk installed.

Using the Embedded Web Server

1Open a Web browser, and then type the printer IP address in the address field.

Notes:

•View the printer IP address on the printer home screen. The IP address appears as four sets of numbers separated by periods, such as 123.123.123.123.

•If you are using a proxy server, then temporarily disable it to load the Web page correctly.

2Click Settings > Security > Disk Encryption.

Note: Disk Encryption appears in the Security Menu only when a formatted, non‑defective printer hard disk is installed.

3From the Disk encryption menu, select Enable.
