(7) 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 drives (counterclockwise), the Fuser roller rotates.
And then, the fuser belt rotates. This roller fuses toner images by heat and
pressure.
2. With the decurler mechanism, the paper is corrected toward up curl to decrease
curl of the paper.
3. At the same time, the eject rollers rotate and eject printouts.
