ABSTRACT:
An image forming apparatus has a printer engine which forms an image on a medium; a unit which supplies the medium to the engine through a path; an element which emits light onto the medium at a position on the path; a receiving element which receives transmitted light of the light emitted which is transmitted through the medium; another receiving element which receives reflected light of the light emitted which is reflected by the medium; a unit which executes a detection through the emission and reception; a unit which determines a characteristic of the medium based on detection signals output by the receiving elements as a result of the detection; and a control unit which executes a control in the apparatus based on the characteristic.
