development bias, and charge unit to operate toner supply for 10 consecutive 1 sec.
intervals from the toner bank to the toner hopper.
This mode finishes automatically after the toner supplied 10 times. Use to determine if
toner supply is operating correctly. If forcing toner supply with this SP does not darken
the image, then toner supply is not operating correctly.
002 Toner Bank Toner Setup
Touch [Execute]. Touching [Execute] checks the toner lever in the toner supply cylinder
and the toner hopper. The toner transport mechanism then supplies toner to the
cylinder or hopper (or both) if the toner level is low.
The 1) toner bank motor, 2) toner supply clutch, and 3) cylinder agitator motor turn on
to supply toner to the toner supply cylinder, then switch off with the toner reaches a
sufficient level.
To supply toner to the toner hopper, in addition to the 3 items above that turn on to
supply toner to the toner supply cylinder, the 4) development agitator motor, and 5)
toner pump motor turn on. This requires about 4 minutes.
Note: Use this SP to fill the toner transport path with toner after cleaning the toner
supply unit, or at installation.
2208 Toner Supply Mode
Selects the toner supply mode: Sensor Control or Image Pixel Count.
[0~1 / 0 / 1]
0: Sensor Control
1: Pixel Count
Select Image Pixel Count only if the TD sensor has failed and cannot be replaced
immediately, so that the customer can use the machine. Return the setting to Sensor
Control after replacing the sensor.
2209 Toner Supply Rate
Adjust the toner supply amount from the hopper for the normal operation.
[100~2000 / 1300 / 10 mg/s]
Increasing this value reduces the toner supply roller clutch on time. Use a lower value if
the user tends to make lots of copies that have a high proportion of black.
2210 ID Sensor Pattern Interval
Changes the interval for making the ID sensor pattern (VSP/VSG detection).
[1~500 / 10 / 1 copy]
If the user normally makes copies with a high proportion of black, reduce the interval.
