Selects the toner supply ratio for
Fixed Supply Mode.
Use a higher value if the user tends
to make lots of copies that have a
high proportion of black.
Adjusts the toner supply rate for
Detect Supply Mode.
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 (VSP/VSG
detection).
Reducing the interval will also reduce
the CPM.
Do not adjust this.
Adjust the VTREF of the TD sensor.
Change this value after replacing the
development unit with another one
that already contains toner.
For example, when using a
development unit from another
machine for test purposes, do the
following:
1. Check the value of SP2220 in both
the machine containing the test unit
and the machine that you are going
to move it to.
2. Install the test development unit,
then input the VTREF for this unit into
SP2220.
3. After the test, put back the old
development unit, and change
SP2220 back to the original value.
Displays the TD sensor output
voltage.
Adjusts the current applied to the
transfer belt during copying on the
1st side of the paper.
