Data Security Notice
This printer contains various types of memory that are capable of storing device and network settings,
information from embedded solutions, and user data. The types of memory-along with the types of data stored
by each-are described below.
•
Volatile memory
—This device utilizes standard Random Access Memory (RAM) to temporarily buffer
user data during simple print and copy jobs.
•
Non-volatile memory
—This device may utilize two forms of non-volatile memory: EEPROM and NAND
(flash memory). Both types are used to store the operating system, device settings, network information,
scanner and bookmark settings, and embedded solutions.
•
Hard disk memory
—Some devices have a hard disk drive installed. The printer hard disk is designed for
device-specific functionality and cannot be used for long term storage for data that is not print-related. The
hard disk does not provide the capability for users to extract information, create folders, create disk or
network file shares, or FTP information directly from a client device. The hard disk can retain buffered user
data from complex scan, print, copy, and fax jobs, as well as form data, and font data.
To erase volatile memory, turn off the printer.
