Statement of volatility
Your printer contains various types of memory that are capable of storing device and network settings, information
from embedded solutions, and user data. The types of memory—along with the types of data stored by each—are
described as follows:
•
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 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.
