In high‑security environments, it may be necessary to take additional steps to make sure that confidential data stored
in the printer hard disk cannot be accessed when the printer—or its hard disk—is removed from your premises.
• 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: Most data can be erased electronically, but the only way to guarantee that all data is completely erased is to
physically destroy each hard disk where data is stored.
Erasing volatile memory
The volatile memory (RAM) installed in your printer requires a power source to retain information. To erase the buffered
data, simply turn off the printer.
Erasing non‑volatile memory
Erase individual settings, device and network settings, security settings, and embedded solutions by following these
steps:
1 Turn off the printer.
2 From the control panel, hold down 2 and 6 while turning the printer on. Release the buttons when the screen with
the progress bar appears.
3 From the Configuration menu, navigate to:
Restore Factory Defaults > Erase Printer Memory > Yes
The printer restarts several times during this process.
4 Touch Back, and then exit the Configuration menu.
Note: The printer performs a power‑on reset, and then returns to normal operating mode.
