Securing printers 58 • The printer is serviced by someone from outside your organization. • The printer is removed from your premises for service. • The printer is sold to another organization. Disposing of a printer hard disk • 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: To guarantee that all data are completely erased, destroy physically each hard disk where data is stored. Erasing volatile memory The volatile memory (RAM) installed on your printer requires a power source to retain information. To erase the buffered data, simply turn off the device. Erasing non‑volatile memory There are several methods for erasing data stored in non‑volatile memory, depending on the type of memory device installed and the type of data stored. • Individual settings-Erase individual printer settings using the control panel or the Embedded Web Server. For more information, see the printer User's Guide. • Device and network settings-Erase device and network settings, and restore factory defaults by resetting the NVRAM from the configuration menu. You can also use the Restore Factory Defaults setting from the Embedded Web Server. • Security settings-Restore factory defaults or erase security settings by selecting an action for the Security Reset Jumper setting in the Embedded Web Server. Then move the hardware jumper on the controller board. • Fax data-If no hard disk is installed, or fax storage uses NAND, then erase fax settings and data by resetting the NVRAM from the configuration menu. You can also use the Restore Factory Defaults setting from the Embedded Web Server. Note: If your printer has a hard disk that has been partitioned for fax storage, then reformat that partition to erase fax data and settings. • Embedded solutions-Erase information and settings associated with embedded solutions by uninstalling the solution, or by restoring factory defaults from the configuration menu. You can also use the Restore Factory Defaults setting from the Embedded Web Server.
