Function
* Adjusts the development bias for copying.
This can be adjusted as a temporary
measure if faint copies appear due to an
aging drum.
* Adjusts the development bias for making
the ID sensor pattern for Vsp
measurement.
This should not be used in the field,
because it affects ID sensor pattern
density, which affects toner supply.
* Adjusts the development bias for copying
onto OHP sheets.
* Adjusts the development potential for
making the ID sensor pattern for Vsp
measurement.
Do not adjust.
Forces the toner bottle to supply toner to
the toner supply unit for 7 seconds.
This mode finishes automatically after the
toner is supplied 7 times (1 s for each
time). This process is not normally needed
in the field for this model.
* Selects the toner supply mode.
Use image pixel count mode only as a
temporary countermeasure if the ID or TD
sensor is defective.
* Adjusts the toner supply rate.
Increasing this value reduces the toner
supply clutch on time. Use a lower value if
the user tends to make lots of copies that
have a high proportion of black.
Changes the interval for making the ID
sensor pattern (V
SP
If the user normally makes copies with a
high proportion of black, reduce the
interval.
