An LED printer constructed with a lower body frame, an upper body frame, a process unit having an upper leading end for mounting a photo-sensitive drum in a housing, an LED frame for supporting an LED head array beneath its right end portion, a pair of through holes formed adjacent to the right end of the LED frame, a pair of blind holes formed on the LED head array facing and aligned with the pair of through holes, and a pair of threaded bolts respectively received by the pair of through holes for connecting the LED head array to the LED frame by respectively fixing the lower ends of the pair of threaded bolts in the pair of blind holes. A pair of compression springs are interposed between the LED frame and head array and enclose corresponding ones of the pair of threaded bolts in order to exert a resilient force on the LED head array. A pair of LED positioning plates formed on both upper side ends of the housing. When an image process unit is installed inside the upper body frame, the upper leading end pushes the lever so as to pivot the LED frame together with the LED head array clockwise, so that both lower side end surfaces of the LED head array respectively contact the pair of LED positioning plates under the resilient force of the pair of compression springs and thus the gap between the photo-sensitive drum and LED head array is properly established and maintained.
