SERVICE PROGRAM MODE TABLES
2207* Forced Toner Supply
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 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 Rate
Adjusts the toner supply rate.
[50~995/5 mg pers 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 Pattern Interval
Adjusts the time interval between making ID sensor patterns onto the drum for
Vsp/Vsg detection.
[-~200/1]
Reduce the interval for copies that contain a high proportion of black.
2220* 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:
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 VREF for this unit into
SP2220.
3)
After the test, put back the old development unit, and change SP2220 back
to the original value.
2223* Vt Display
Displays the current TD sensor output voltage.
[0~5.0 V]
