Disposing of a printer hard disk

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

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 are 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:

1Turn off the printer.

2Hold down 2 and 6 on the keypad 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, a list of functions appears on the printer display instead of the standard home screen icons.

3Touch Wipe All Settings.

The printer will restart several times during this process.

Note: Wipe All Settings securely removes device settings, solutions, jobs, and passwords from the printer memory.

4Touch Back > Exit Config Menu.

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