ABSTRACT:
A method of measuring a paper size using a paper feeder having a fixedly mounted body part and a fastener apparatus movable depending on the paper size includes receiving light reflected from the body part with respect to an amount of a sent light, measuring the amount of the received light, and extracting information on a paper size corresponding to the measured amount of light from stored information. The extracted information of the paper size can be transmitted to a display unit, so that a user can recognize the information.
