MX3500N PHOTOCONDUCTOR SECTION i – 3
4) The whole surface of the OPC drum is discharged.
By radiating the discharge lamp light to the discharge lens,
light is radiated through the lens to the OPC drum surface.
When the discharge lamp light is radiated to the OPC drum
CGL, positive and negative charges are generated.
Positive charges generated in CGL are attracted to the nega-
tive charges on the OPC drum surface. On the other hand,
negative charges are attracted to positive charges in the alumi-
num layer of the OPC drum.
Therefore, positive and negative charges are balanced out on
the OPC drum surface and in the aluminum layer, reducing
positive and negative charged to decrease the surface voltage
of the OPC drum.
