Erasing volatile memory, Back Exit Config Menu

Using C746x

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, turn off the printer.

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 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 powered up, the printer displays a list of functions.

3Press the up or down arrow button until Wipe All Settings appears. The printer will restart several times during this process.

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

4Navigate to:

Back > Exit Config Menu

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

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 scan, print, copy, and fax jobs, by securely overwriting files that have been marked for deletion.
