3. OPERATION AND TIMING
The CLC1000 is equipped with a laser unit for each color (Y, M, C, Bk), each unit directing a laser beam
against its corresponding photosensitive drum. The polygon mirror consists of top and bottom blocks,
generating four channels of laser beams as shown in Figure 3-402.
Figure 3-402
Since the positions of the laser units and the direction of rotation of the polygon mirror differ for M/Y and
C/Bk, the laser beam scans the photosensitive drums in the opposite directions as shown in Figure 3-403.
