Data security notice

Identifying printer memory
•
Volatile memory—The printer uses standard random access memory (RAM) to buffer user data temporarily
during simple print and copy jobs.
•
Non-volatile memory—The printer may use two forms of non-volatile memory: EEPROM and NAND (flash
memory). Both types are used to store the operating system, printer settings, network information, scanner
and bookmark settings, and embedded solutions.
•
Hard disk memory—Some printers have a hard disk drive installed. The printer hard disk is designed for
printer-specific functionality and cannot be used for the long‑term storage of 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 transfer FTP information directly from a client device. The hard disk can retain buffered
user data from complex print jobs, form data, and font data.
The following parts can store memory:
•
Printer control panel
•
User interface controller card (UICC)
•
Controller board
•
Optional hard disks
Note: The printer control panel and controller board contain NVRAM.
