ABSTRACT:
An apparatus for and method of operating a printer recognizes and allocates a unique identification (ID) to each of a plurality of trays, which are mounted in a printer as options. The apparatus includes a signal transmission unit transmitting a recognition signal to trays from a main frame of a printer, and a recognition unit reading the recognition signal from the trays, recognizing unique codes which correspond to the trays, and transmitting the unique codes of the trays to the main frame of a printer. The unique IDs of trays, which are mounted as options, can be recognized without a manual operation by a user, thereby giving convenience to the user and preventing errors from occurring during an operation of the printer.
