Erasing printer hard disk memory

Using the printer control panel



1. Turn off the printer.



2. Hold 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.



3. Touch 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.


4. Touch 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.


5. Touch Back > Exit Config Menu.

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