Securing the printer

Statement of Volatility

Your printer contains various types of memory that can store device and network settings, and user data.

Type of memory

Volatile memory

Non-volatile memory

Description

Your printer uses standard random access memory (RAM) to temporarily buffer user data during simple print jobs.

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

•

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.
