Securing the printer 224

Types of memory

Hard disk memory

Description

Some printers have a hard disk drive installed. The printer hard disk is designed for device-specific functionality. This lets the device retain buffered user data from complex scan, print, copy, and fax jobs, as well as form data, and font data.

Erase the content of any installed printer memory in the following circumstances:

•The printer is being decommissioned.

•The printer hard disk is being replaced.

•The printer is being moved to a different department or location.

•The printer is being serviced by someone from outside your organization.

•The printer is being removed from your premises for service.

•The printer is being sold to another organization.

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 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

•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 touch screen displays a list of functions, instead of the standard home screen icons.
