Abstract

A Customer Replaceable Unit Monitoring (CRUM) chip, an image forming apparatus, and a method of authenticating are provided. The apparatus includes a main body that includes a main controller controlling operations of the apparatus, a consumable unit mounted on the main body to communicate with the main controller, and a CRUM chip that is provided in the consumable unit and stores information regarding the consumable unit. The main controller and the CRUM chip transmit and receive signals that include data and integrity detection data between each other. The integrity detection data is generated by accumulating and examining integrity detection data included in a previous signal.

Description

[0001] This application is a divisional application of an invention patent application with an application date of July 18, 2013, an application number of 201380073466.8, and an invention title of "CRUM chip and imaging device for authentication and communication and its method". technical field [0002] Embodiments discussed herein relate to CRUM chips and imaging devices and methods thereof for authentication and communication, and more particularly, to authentication and communication during communication for use of integrity detection data to detect whether data is complete Customer replaceable unit monitoring (Customer Replaceable Unit Monitoring, CRUM) chips and imaging devices, and methods thereof. Background technique [0003] As computers have become more ubiquitous, the rate at which peripheral devices for computers have spread has also increased. Computer peripherals include imaging devices such as printers, fax machines, scanners, copiers, and multifunction print...
