Charging process

In the charging process, the OPC belt is evenly charged by the charger. See “Printer theory of operation” on page 1-19for 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.
