Charge

In this machine,  there are charge rollers for each color to reduce the ozone generation.

The charge roller, which is a rubber-covered roller that has a metal shaft, rotates in the forward direction contacting with the OPC drum and applies a charge to the OPC drum surface uniformly.

The life of the PCU is extended by separating the charge roller from the OPC drum by about 50 µ.

When the charge roller is dirty, an uneven charge is generated, so a cleaning roller (charge roller) always contacts the charge roller.
