Charging process
In the charging process, the OPC belt is evenly charged by the
charger. See “Printer theory of operation” on page 1-19 for
charger unit location.
The charger unit consists of a charging brush and a discharge roller.
1. The charge brush charges the OPC belt surface to
-Vo(V) potential. The charge on the surface of the OPC belt is
then smoothed to an even -Vo(V) by the discharge roller.
2. The charger unit controls the grid to a constant voltage of ZD(V)
for even charging.
