Statement of Volatility

Type of memory Description

Volatile memory The printer uses standard random access memory (RAM)

to buer 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.
