2.4.7 OPTICAL PATH
The output path from the laser diode to the drum is shown above.
The LD unit [A] outputs eight laser beams to the polygonal mirror [B] (six mirror
surfaces) through the cylindrical lens [C] and the 1st mirror [D].
Each surface of the polygon mirror reflects eight full main scan lines. The laser beams
go to the F-theta lens 1 [E], F-theta lens 2 [F], BTL (barrel toroidal lens) [G], and mirror
[H]. Then these laser beams go to the drum through the toner shield glass [I].
The laser synchronizing detector [J] determines the main scan starting position. This
sensor sends a synchronization signal when the laser synchronization detector mirror
[K] reflects the laser beam to the detector as the laser beam starts its sweep across
the drum.
The laser synchronization detector detects only the beams emitted from Channels 1
and 0, the uppermost beams of each parallel array.
