Statement of Volatility
Your scanner contains various types of memory that are capable of storing device and network settings, information
from embedded solutions, and user data. The following are the types of memory and the types of data they store:
• Volatile memory—Your device utilizes standard Random Access Memory (RAM) to temporarily buffer user data
during simple print and copy jobs.
• Non‑volatile memory—Your device may utilize two forms of non-volatile memory: EEPROM and NAND (flash
memory). Both types are used to store the operating system, device settings, network information, scanner and
bookmark settings, and embedded solutions.
• Hard disk memory—Some devices have a hard disk drive installed. The scanner 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.
There are several circumstances where you may want to erase the contents of memory of devices installed in the
scanner. A partial list includes:
• The scanner is being decommissioned.
• The scanner hard drive is being replaced.
• The scanner is being moved to a different department or location.
• The scanner is being serviced by someone from outside your organization.
• The scanner is being removed from your premises for service.
Disposing of a printer or scanner hard drive
Note: Not all printers or scanners 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 scanner hard disk cannot be accessed once the scanner—or its hard disk—is removed from your premises.
• Degaussing—Flushes the hard drive 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: 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 in your scanner requires a power source to retain information. To erase the
buffered data, simply turn off the scanner and the printer.
