3) After transfer operation, remaining toner is removed by the
cleaning blade.
Toner removed from the OPC drum surface is transported to
the waste toner section by the waste toner transport screw.
OPC drum rotation control
The OPC drum (K) is driven by the DV motor (DVM_K), and
the rotation speed is monitored by the OPC drum rotation sen-
sor (DHPD_K).
The color OPC drums (C, M, and Y) are driven by the DV
motor (DVM_CL), and the rotation speed is monitored by the
OPC drum rotation sensor (DHPD_CL).
Based on the signals monitored by the two sensors, the rota-
tion speeds of K OPC drum and the color OPC drums and the
rotation phase are controlled.
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.
