A laser scanning unit module is provided. The laser scanning unit module (30) includes at least one or more laser scanning units (40, 50, 60, 70), a base plate (31) on which the laser scanning units (40, 50, 60, 70) are installed, and a memory device (80) for storing data required for scanning control of each laser scanning unit (40, 50, 60, 70) installed on the base plate (31). In the LSU module (30), information for controlling the scanning synchronization of each LSU (40, 50, 60, 70) is provided from the memory device (80) such that misregistration of images is prevented after the LSU module (30) is installed in the printer. Thus, a test printing process for controlling the scanning synchronization is not required. Also, when replacing the laser scanning unit module of a printer, a required laser scanning unit module can be easily selected by reading information of the scanning characteristics provided from the memory device. <IMAGE> |
