• Mirror / Lens
    Each color LD board [A] emits light at the time of paper transfer, which heads to each color drum through the following parts; the cylinder lens (laser beam radial-adjustment), the polygon mirror (horizontal-line scan) [D], the scan lens (L1) [C], the 1st mirror [B], the scan lens (L2) [K], 2nd mirror [J], 3rd mirror [G], the laser synchronization mirror [I], the dust shield glass [H].
    Lower layer (C, Y) beams go to each color drum through the following parts: the cylinder lens, polygon mirror [E], the scan lens (L1) [L], the scan lens (L2) [P], the 1st mirror [O], the synchronization mirror [N], the dust shield glass [M].
  • Polygon Motor
    The polygon motor [F] is composed of a motor and two mirrors attached on a drive shaft (four-sided double-layered mirrors). Laser beams are emitted to the polygon mirrors [D], [E] to write two colors alternately.
  • Scan Lens Adjustment
    For each color, the scan lens (L2) [A] has an image skew correction motor [B] to correct skew. This corrects color registration errors in the main scan direction.
