3.5 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 transfer FTP information directly from a client
device. The hard disk can retain buffered user data from complex print jobs, as well as form data
and font data.
To erase volatile memory, turn off the printer.
To erase non-volatile memory, see the menu item under
