Quenching - Ricoh Neptune-P1 Service Manual

6. Details
After you put the empty bottle back in the machine, if toner is not detected by the used toner bottle sensor,
then the machine returns to normal operation mode. If toner is detected, the used toner bottle motor turns
on for 30 seconds. If toner is still detected, then the machine stops and the bottle must be removed.

The quenching lamp [A], an array of LEDs, is behind the LPH [B].
After the drum is cleaned by the cleaning blade, light from the quenching lamp removes unwanted charge
on the drum. This prepares the drum for the subsequent copy cycle.
The quenching lamp switches on and off with the drum motor (the lamp stays on while the OPC drum turns).
