•
Any potential remaining on the surface of the PC Drum is neutralized by both light from the Erase Lamp
and a DC negative voltage applied by the Charge Neutralizing Sheet.
•
The Charge Neutralizing Sheet applies a negative charge on the surface of the PC Drum which is
positively charged by the Image Transfer Roller. A voltage of -820V is applied to the Charge Neutralizing
Sheet from the High Voltage Unit. The Erase Lamp then illuminates the surface of the PC Drum to
further neutralize it.
•
The Erase Lamp consists of ten tungsten lamps.
