Abstract

A printer and a control method thereof. The printer includes an optical scanner for scanning light to a photosensitive medium according to image information, a developing unit for developing an electrostatic latent image formed by the optical scanner, a transfer unit for transferring the image of the photosensitive medium to paper, an engine driving unit for driving the optical scanner and the developing unit, a feed unit having a paper feed distance shorter than an image feed distance, and being disposed at a predetermined position of a main body, for stacking paper, a residual amount sensing unit for sensing a residual amount of paper, and a control unit for controlling the engine driving unit to perform a normal printing mode when the residual amount of paper exceeds a predetermined limit value, and to perform a contamination prevention mode when the residual amount of paper is below the predetermined limit value. As a result, the photosensitive medium is prevented from being contaminated due to lack of paper in the consecutive printing process, by using the feed unit having the paper feed distance shorter than the image feed distance.
