Statement of Volatility
Type of memory Description
Volatile memory The printer uses standard random access memory (RAM)
to buer 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 buered
user data from complex print jobs, form data, and font
data.
