2.4.4 Transfer

As the paper travels between the BTR and the drum surface, the Bias
Transfer Roll (BTR) applies a positive charge to the back of the printing
paper. This positive charge transfers the negative charged toner image
from the drum surface to the top surface of the paper. The toner image
is now on the paper and the paper is now stuck to the drum surface, due
to the relative electrical differences between the negative electrical
charge of the inner conductive layer of the drum and the positive
electrical charge of the paper.

Figure 2-28. Transfer

2.4.5 Detack

After the toner image transfers to the surface of the paper, the Detack
Saw (a thin strip of metal that resembles a saw blade) applies a low
voltage negative charge to the back of the paper to neutralize the
positive voltage that was applied to it by the BTR. Once the positive
voltage is neutralized, the paper strips releases easily from the drum
surface and continues along the paper path to the Fuser.
