Multi-function input/output device and method

A multi-function input/output device comprising:

• a document input unit acquiring document data from a document;
• a document-input control setting unit controlling the document input unit according to unit-control-setting information of the document input unit;
• a document data processing unit processing the document data acquired by the document input unit;
• a document-data-processing control setting unit controlling the document data processing unit according to unit-control-setting information of the document data processing unit;
• a document data output unit outputting processed document data;
• a document-data-output control setting unit controlling the document data output unit according to unit-control-setting information of the document data output unit;
• an optical reading unit optically reading an optically readable code from a device control setting medium on which device control setting information, including use authentication information and at least one unit-control-setting information for the document input control setting unit, the document-data-processing control setting unit, and the document-data-output control setting unit, is recorded;
• a control setting information recognizing unit recognizing the device control setting information, including the use authentication information, from the optically readable code read by the optical reading unit;
• a user authentication unit authenticating a user by using a use authentication code of the use authentication information;
• and
• a setting processing unit setting at least one of the respective unit-control-setting information of the document input unit, the document data processing unit, and the document data output unit, based on a recognition result of the device control setting information and the use authentication information.
