Check the surface of the cylinder of the developer unit is not worn, remember that the cylinder of the developer unit of this machine is black.
check if values ​​are equal up to the values ​​of service mode.

Go to SM and disable the potential control.
COPIER>OPTION>BODY>PO-CNT (enable/disable potential control)
0: disable potential control
1: enable potential control

If u want it "on" then change C/T corona and clean the PO senzor.
There is no same problems
