IMAGING FORMING DEVICE HAVING A DIAGNOSIS FUNCTION BY USING POTABLE STORAGE DEVICE AND DIAGNOSIS METHOD OF IMAGAING FORMING DEVICE USING POTABLE STORAGE DEVICE

摘要

The image forming apparatus provided with a method of diagnosing the functions of the image forming apparatus using a removable storage device, a diagnostic program of the image forming apparatus is stored, and such a function is disclosed. The present invention is stored on removable storage accessory image forming apparatus diagnostic method comprising the steps of: in an image forming apparatus, diagnosis method for diagnosing the functionality of the image forming apparatus, providing an interface with a removable storage device the diagnostic program stored in the portable storage device using storing the diagnosis result based on the steps to run the diagnostic program downloaded in step, a storage medium that stores a download the diagnostics to the storage medium for diagnosing the function of each component of the image forming apparatus, and diagnostic programs running on a portable storage device and in that it comprises the steps according to claim. Accordingly, the diagnostics of the image forming apparatus is upgraded, and the diagnostic program easier it is stored in the external removable storage device, it is unnecessary additional cost of increased space for the diagnostic program upgrade when the image forming apparatus of the internal storage medium.
