[OPC Refresh]
1 Temperature * This SP determines the temperature threshold for
determining whether refresh mode is done just
after the machine is switched on.
The charge roller generates NOx (nitrogen
oxides), and these contaminate the OPC drum
surface and may cause a smeared image.
Just after the main switch is turned on, if the
temperature measured by both the thermistor
located at the right side on the laser optics
housing unit and the temperature/humidity sensor
is greater than the temperature specified in this
SP mode, refresh mode is done before initial
process control.
During refresh mode, toner is developed on the
OPC with 50V development potential and cleaned
to remove NOx. This cycle is repeated a few
times.

2 Humidity * This SP determines the humidity threshold for
determining whether refresh mode is done just
after the machine is switched on.
Just after the main switch is turned on, if the
humidity measured by the temperature/humidity
sensor is greater than the humidity specified in
this SP mode, refresh mode is done before the
initial process control self-check.

3 Prints * Specifies how often refresh mode is done.
When the total number of prints since the last
refresh mode exceeds the number specified in this
SP mode, refresh mode is done before the job
end process control self-check.
