Warning—Potential Damage: Restoring factory defaults returns most printer settings to the original factory default
settings. Exceptions include the display language, custom sizes and messages, and network/port menu settings. All
downloads stored in the RAM are deleted. Downloads stored in the flash memory or in a printer hard disk are not
affected.
From the home screen, navigate to:
> Settings > General Settings > Factory Defaults > Restore Now >
Securing the printer
Locking the system board
To limit access to the system board, attach a security lock to the printer in the location identified in the illustration. The
printer is compatible with most laptop computer security locks.
Statement of Volatility
Your printer contains various types of memory that can store device and network settings, and user data.
Types of memory Description
Volatile memory Your printer uses standard Random Access Memory (RAM)
to temporarily buffer user data during simple print and copy
jobs.
Non-volatile memory Your printer may use 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 printers have a hard disk drive installed. The printer
hard disk is designed for device-specific functionality. This lets
the device retain buffered user data from complex scan, print,
copy, and fax jobs, as well as form data, and font data.
