Erasing Volatile Memory; Erasing Non-Volatile Memory - Lexmark MS610dn Administrator's Manual

Using security features in the Embedded Web Server
•
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 FTP information directly from a client device. The hard disk can retain buffered user data from complex
scan, print, copy, and fax jobs, as well as form data, and font data.
You may want to erase the contents of the memory devices installed in your printer when:
•
The printer is being decommissioned.
•
The printer hard drive is being replaced.
• 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.
Disposing of a hard drive
Note: Not all printers have a hard disk installed.
In high‑security environments, it may be necessary to take additional steps to ensure that confidential data stored on
the printer hard disk cannot be accessed once the printer or its hard disk is removed from your premises. While most
data can be erased electronically, you may want to consider one or more of the following actions before disposing of
a printer or hard disk:
•
Degaussing—This flushes the hard drive with a magnetic field that erases stored data.
•
Crushing—This physically compresses the hard disk to break component parts and render them unreadable.
• Milling—This physically shreds the hard disk into small metal bits.
Note: While most data can be erased electronically, the only way to guarantee that all data is completely erased is to
physically destroy each memory device on which data could have been stored.

Erasing volatile memory

The volatile memory (RAM) installed on your printer requires a power source to retain information. To erase the
buffered data, simply turn off the device.
Erasing non‑volatile memory
There are several methods available for erasing data stored in non‑volatile memory, depending on the type of memory
device installed and the type of data stored by that device.
• Individual settings—You can erase individual printer settings using the printer control panel or the printer
Embedded Web Server. For more information, see the User's Guide.
•
Device and network settings—You can erase device and network settings and restore factory defaults by resetting
the NVRAM using the printer Config menu.
•
Security settings—You can restore factory defaults or erase security settings by selecting a behavior for the Security
Reset Jumper in the Embedded Web Server, and then moving a hardware jumper located on the motherboard.
