Figure 5 Side View Block Diagram of the Transfer Process
5. Discharge (Figure 6)
After the toner image has transferred to the surface of the paper, the Detack Saw (a thin
strip of metal that resembles a saw blade) applies a negative charge to the back side 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 easily off of the drum surface.

6. Fusing (Figure 7)
The paper moves to the Fuser Assembly where it passes between the Heat Roll and the
Pressure Roll. The Heat Roll melts the toner image and bonds it permanently to the
paper. The paper then is transported to the output tray.
7. Cleaning (Figure 7)
The Cleaning Blade removes any toner that remains on the drum after the transfer pro-
cess. Immediately after passing the Cleaning Blade, the drum passes under the BCR.
The BCR applies an AC voltage to the surface of the drum to neutralize any electrical pat-
terns remaining from the last print cycle.
