2.4.7 Erase Lamp

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.
