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. Nonvolatile memory The printer may use two forms of non-volatile memory: EEPROM and NAND (flash memory). Both types store the operating system, printer settings, and network information. They also store scanner and bookmark settings and embedded solutions. Hard disk storage drive 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. Intelligent storage drive (ISD) Some printers may have an ISD installed. ISD uses nonvolatile flash memory to store 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 or ISD is replaced. • The printer is moved to a different department or location. • The printer is serviced by someone from outside your organization.
