Rotates the toner bottle to supply toner to the toner supply unit. Press Execute to force toner
supply.
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.
2208 [Toner Supply Mod] Toner Supply Mode
Selects the toner supply mode: Sensor Control or Image Pixel Count.
[0~1/1]
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 Rat] Toner Supply Rate
Adjusts the toner supply rate.
[50~995/5 mg per sec]
Increasing this value reduces the time the toner supply clutch remains on. Use a lower value if
the user tends to make many copies that have large areas of black.
2210 [ID Sensor Patter] ID Sensor Pattern Interval
Adjusts the time interval between making ID sensor patterns onto the drum for Vsp/Vsg de-
tection.
[-~200/1]
Reduce the interval for copies that contain a high proportion of black.
2220
[Vref Manual Sett] Vref Manual Setting
Adjusts the TD sensor reference voltage (Vref) manually.
[1.00~4.00/0.11 V]
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:
• Check the value of SP2220 in both the machine containing the test unit and the machine
that you are going to move it to.
