Page 31 Chapter 2 The leaser beam reflected by the 4 facet mirror moves through the imaging lens arranged in front of the 4 facet mirror and the reflecting mirror to reach and focus on the photosensitive drum. When the 4 facet mirror rotates at a specific speed, the laser beam scans the photosensitive drum in keeping with the mirror rotation, thus drawing static images on the photosensitive drum.

Chapter 2 Pickup and Feed Operation (from the cassette) If the cassette paper sensor detects the presence of paper while the absence of paper is identified in the manual feed pickup assembly, the machine picks up paper from the cassette. When the main motor operates and the cassette pickup solenoid goes on, the cassette pickup roller makes a single rotation to pick up paper.
