Abstract
An image-forming apparatus and print media recognition method therefor, wherein the apparatus comprises a first light-emitting element for emitting light to a print medium at a predetermined first incident angle, a second light-emitting element for emitting light to the print medium at a predetermined second incident angle, and a light-receiving element installed along an optical axis of total reflection light emitted from the first light-emitting element and reflected from a surface of the print medium. The apparatus further comprises a control unit for controlling the first and second light-emitting elements to alternately emit light for deciding a print medium material based on a reflection amount of light received by the light-receiving element and establishing print conditions adapted to the print media.
