2. Theory of Operation
(5) Fuser unit and paper unloading
1. The fuser unit and the unloading roller are driven by the DC motors as
shown in Fig. 2-8. When the fuser motor rotates (in counter-clockwise
direction), the heat roller rotates. This heat roller fuses the toner image on
the paper by the heat and pressure.
2. At the same time, the unloading roller rotates to unload the paper.
(6) Opening operation of the covers of the color registration error sensor and of the
density sensor
1. When the solenoid activated to ON as shown in Fig. 2-9, the link lever is
moved to open the covers of the color registration error sensor and of the
density sensor.
2. When the solenoid is deactivated to OFF, the spring presses the covers
so that the covers of the color registration error sensor and of the density
sensor are closed.
