Belt discharge (erase lamp) process

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.
