Abstract: An image forming device is provided. The device includes a main body which includes a main controller controlling operations of the image forming device, a consumable unit mounted on the main body to enable communication with the main controller, and a CRUM chip which is provided in the consumable unit and stores usage information of the consumable unit and characteristics information The main controller and the CRUM chip transmit and receive signals which include data and integrity detection data between each other. The integrity detection data is generated by accumulating and reflecting integrity detection data included in a previous signal.

Abstract: An image forming apparatus and a document description information input method thereof includes a display unit on which a graphic user interface is displayed and a storing unit in which at least one document is stored, the document description information input method includes displaying a list including at least one document on the display unit; selecting at least one document from the list; determining whether there exists any description information set for the document, selecting a description information input menu if there exists no description information set for the document; and inputting the description information in the image forming apparatus using the description information input menu. With this configuration, it is possible to easily identify documents required by a user by inputting description information on documents stored in the apparatus through a GUI and storing the input description information to correspond to the stored document.
