2. DESCRIPTION OF OPERATION
(5) Fuser unit and paper ejection
1. As illustrated in Figure 2-8, the fuser unit and the eject roller are driven by the
DC motor. As the fuser motor rotates (counterclockwise), the heat roller rotates.
This roller fixes toner images by heat and pressure.
2
. At the same time, the eject rollers rotate and eject printouts.
(6) Cover-opening motion of the color registration sensor and the density sensor
1. As illustrated in Figure 2-9, when the solenoid is energized, the link lever moves,
causing the cover of the color registration sensor and the density sensor to
open.
2. As the solenoid is de-energized, the spring pushes the cover, causing the cover
of the color registration sensor and the density sensor to close.
