Ricoh A156 - Quenching

10. QUENCHING
In preparation for the next copy cycle, light from the quenching lamp [A]
neutralizes any charge remaining on the drum.
The quenching lamp consists of a line of nine LEDs extending across the full
width of the drum.
Red LEDs are used to reduce ultra violet light which would cause light
fatigue of the OPC drum.
