Office automation device and method of installing, reinstalling, and upgrading a driver thereof

摘要

An office automation (OA) device and methods of installing, reinstalling, and upgrading a driver of the OA device. The OA device includes a class information storage unit to store class information based on which a host device identifies the OA device and to output class information when being accessed by the host device; an program storage unit to store a driver program and a driver installation program for the OA device; and a control unit to control the host device to access the program storage unit when the class information read from the class information storage unit by the host device is a CD-ROM class, to control the OA device to perform inherent functions of the OA device when the class information is an inherent class of the OA device, and to change the class information set in the class information storage unit to a predetermined class in response to completion of installation of the OA device driver or an external input. The method of installing an OA device driver stored in an OA device in a host device connected to the OA device includes installing the OA device driver in the host driver by enabling the OA device to be recognized a class different from an inherent class of the OA device.
