3.2 OPTICAL PATH
The output path from the laser diode to the drum is shown above.
The LD unit [A] outputs the laser beam to the polygon mirror [B] through the
cylindrical lens [C].
Each surface of the polygon mirror reflects a full main scan line. The laser
beam goes to the F-theta mirror [D], 1st mirror [E], and BTL [F]. The 2nd
mirror [G] reflects the laser beam to the drum through the toner shield glass.
The laser synchronizing detector [H] determines the main scan starting
position.
