Statement of Volatility
Type of memory | Description |
|---|---|
Volatile memory | The printer uses standard random access memory (RAM) to buffer temporarily user data during simple print and copy jobs. |
Non-volatile memory | The printer may use two forms of non-volatile memory: EEPROM and NAND (flash memory). Both types are used to store the operating system, printer settings, network information, scanner and bookmark settings, and embedded solutions. |
Hard disk memory | Some printers may have a hard disk drive installed. The printer hard disk is designed for printer-specific functionality. The hard disk lets the printer retain buffered user data from complex print jobs, form data, and font data. |
Erase the content of any installed printer memory in the following circumstances:
- The printer is decommissioned.
- The printer hard disk is replaced.
- The printer is moved to a different department or location.
- 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
To guarantee that all data are completely erased, destroy physically each hard disk where data is stored.
