This machine changes the transfer belt bias voltage for every mode and
every copy cycle.
For 1C copy mode, which is more influenced by environmental conditions,
the transfer belt bias output is divided into five ranges by four threshold
values (as mentioned in the table above) and is determined by the output of
the humidity sensor. Only three different bias settings are present as the
factory setting for each environment.
The transfer belt bias voltage data can be monitored in the SP Adjustment
Mode P-5 and 6. These data should not be changed. For more details, see
the SP Mode Section.
