Securing the printer 33

Statement of Volatility

Your printer contains various types of memory that can store device and network settings, and user data.

Type of memory Description

Volatile memory Your printer uses standard random access memory

(RAM) to temporarily buer user data during simple print jobs.

Non-volatile memory Your printer may use two forms of non-volatile memory:

EEPROM and NAND (ﬂash memory). Both types are used to store the operating system, device settings, network information and bookmark settings, and embedded solutions.

Hard disk memory Some printers have a hard disk drive installed. The printer

hard disk is designed for printer-speciﬁc functionality. This lets the printer retain buered user data from complex print 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 dierent 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 are completely erased is to physically destroy each hard disk where data is stored.
