2.2.4 Quenching
In preparation for the next copy cycle, light from the quenching lamp [A]
neutralizes any charge remaining on the drum [B].
The quenching lamp turns on at the same time as the drum motor activates.
Red LEDs are used for the quenching lamp to reduce ultra-violet light that
would cause light fatigue on the OPC drum.
