ABSTRACT:
An apparatus for obtaining data on scan starting times for laser scanning units for a color printer is provided. The apparatus includes charge-coupled devices arranged to receive light beams emitted from the respective laser scanning units to predetermined positions at the ends of respective image writing regions; an analog/digital converter for converting analog signals output from the charge-coupled devices into digital signals, the analog signals corresponding to the receiving of the light beams emitted from the laser scanning units; and a central processing unit for adjusting the driving of laser emission of the respective laser scanning units and reading the received digital signals to obtain data on the scan starting time. Adjusting synchronization of scanning is then accomplished by simply storing the data on the scan starting times obtained by the apparatus in the printer. Thus, an additional process of test printing is not required.
