Electrical belt cleaning is accomplished by an erase lamp radiating
on the OPC belt. Radiation discharges the residual charge -VR(V)
remaining on the belt after the first transfer process. Electrical
cleaning occurs after each toner color transfer. The erase lamp is a
luminous source consisting of 24 light emitting diodes. After the
electrical belt cleaning, the OPC belt is cleaned with a mechanical
blade.
