[FlashROM]

A memory in which MFP Control Software is installed.

[RAM]

A volatile memory that is used for an image processing memory.

[NVRAM]

A non-volatile memory in which MFP Control Data to configure the MFP operation is stored.

[Ic Key]

A security chip that has the functions of random number generation and encryption

key generation, and

is used to detect the tampering of MFP Control Software.

Ic Hdd

Ic Hdd is a security chip that has the functions to encrypt the information to be stored on HDD and to decrypt

the information to be read from HDD.

HDD

HDD is a hard disk drive in which image data and user information for identification and authentication are

stored.

Network Unit
