Your printer contains various types of memory that can store device and network settings, and user data.
Your printer uses standard random access memory (RAM) to temporarily buffer user data during simple print jobs.
Your printer may use two forms of non-volatile memory: EEPROM and NAND (flash memory). Both types are used to store operating system, device settings, and network information.
