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 operating system, device settings, and network
	information.

Erase the content of any installed printer memory in the following circumstances:

•The printer is being decommissioned.

•The printer is being moved to a different department or location.

•The printer is being serviced by someone from outside your organization.

•The printer is being removed from your premises for service.

•The printer is being sold to another organization.

Erasing volatile memory

The volatile memory (RAM) installed in your printer requires a power source to retain information. To erase the buffered data, simply turn off the printer.

Erasing non‑volatile memory

•Individual settings, device and network settings, security settings, and embedded solutions—Erase information and settings by selecting Wipe All Settings in the Configuration menu.

•Fax data—Erase fax settings and data by selecting Wipe All Settings in the Configuration menu.
