<p>The LED printer includes: a photosensitive drum (2); a resist roller (5) for feeding a printing medium to the photosensitive drum (2) at a first constant speed; a fixing device (6) for discharging the printing medium from the photosensitive drum (2) at a second constant speed; a separation type LED head (3) arranged zigzag; and a printing control circuit (1) for detecting a position of the printing medium fed by the resist roller (5) or the fixing device (6) and adjusting printing timings of a first portion LED head (31,33) and a second portion LED head (32) based on the detected position and the LED head interval. The LED printer can normally correct a print length in each of a front end region and a rear end region of a sheet.</p> |
