Function/[Setting]
Adjusts the TD sensor reference voltage
(Vref) manually.
[0~5.0 / 2.5 / 0.01 V]
Change this value after replacing the
development unit with another one that
already contains toner. To use a
development unit from another machine
for test purposes:
1) Check the value of SP2220 and
SP2906 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 VREF for this unit into
SP2220 and the Vcont for this unit into
SP2906.
3) After the test, put back the old
development unit, and change
SP2220 and SP2906 back to the
original value.
Displays the current TD sensor output
voltage. [0~5.0 / 2.5 / 0.01 V]
This SP removes toner from the toner
bank and sends it to the toner hopper.
After turning the toner supply motor and
the toner bank motor on, the toner supply
coil clutch turns on and off at 2 second
intervals. The motors and clutch stop
when the toner near-end sensor (in the
toner bank unit) detects no toner. Even if
the sensor continues to detect toner, this
operation stops when the clutch has been
turned on and off 10 times, so this SP
may have to be repeated to clean out the
system completely.
Displays the toner supply mode used for
the last copy.
1: ID Sensor and TD Sensor (from the
11th copy, using VT – VREF)
2: ID Sensor and TD Sensor (using
VSP/VSG) – before the 10th copy of a
job
3: TD Sensor – temporary mode when ID
sensor output is abnormal
4: Image Pixel Count
Adjusts the current applied to the transfer
belt during copying, depending on the
side, media type, and operation mode
(normal or low speed).
