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 illumi-
nates the surface of the PC Drum to further neutralize it.
• The Erase Lamp consists of ten tungsten lamps.
