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.

Securing the printer
Using the security lock feature
The printer is equipped with a security lock feature. When a lock compatible with most laptop computers is attached,
the printer is locked. When locked, the controller board shield and the controller board cannot be removed. Attach a
security lock to the printer in the location shown.
Statement of Volatility
Your printer contains various types of memory that can store device and network settings, and user data.
Type of memory
Description
Volatile memory
Your printer uses standard
random access memory
(RAM) to
temporarily buffer user data during simple print 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, 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 print jobs,
as well as form data, and font data.
