3.2.4 Fixing
stage
The toner image transferred to the paper in the transfer stage is held only by electrostatic
attraction and slight physical adhesion, so even a light touch will smear the image.
In the fixing stage, the toner image is fixed by heating the paper and applying pressure.
This fuses the toner particles to the paper to make a permanent image.
Step 6 Fixing
Figure 2.15
The upper roller surface is PFA-coated. The upper and lower roller surfaces are
grounded via a diode to prevent the negative potential of the upper roller becoming higher
than that of the lower roller, resulting in the toner being drawn to the lower roller, and
adhering to the lower roller surface.
3.2.5 Drum cleaning stage
In the transfer stage, not all the toner is transferred to the paper. Some remains on the
photosensitive drum. This residual toner is cleaned off in the drum cleaning stage so that
the next print image will be clear.

drum
Figure 2.16
Prior to the next printing, the residual toner on the drum surface is scraped away by the
cleaning blade to clean the drum surface. The removed toner is collected in the cleaner
container.
