Disposing of a printer hard disk
Note:
Some printer models may not have a printer hard disk installed.
In high
‑
security environments, it may be necessary to take additional steps to make sure that confidential data
stored in the printer hard disk cannot be accessed when the printer—or its hard disk—is removed from your
premises.
•
Degaussing
—Flushes the hard disk with a magnetic field that erases stored data
•
Crushing
—Physically compresses the hard disk to break component parts and render them unreadable
•
Milling
—Physically shreds the hard disk into small metal bits
Note:
Most data can be erased electronically, but the only way to guarantee that all data is completely
erased is to physically destroy each hard disk where data is stored.
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.
Finding printer security information
In high-security environments, you may need to take additional steps to make sure that confidential data stored
in the printer cannot be accessed by unauthorized persons. For more information, check the
“Embedded Web
Server — Security” Administrator’s Guide
from your printer CD or from our Web site, or contact the place where
you purchased the printer.
