SP2000 Drum
D131/D132/D133 3-24 SM Appendix
2220
Vref Manual Setting
Adjusts the TD sensor reference voltage (Vref) manually.
[1 to 4/2.5/0.01 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.
Install the test development unit, then input the VREF for this unit into
SP2220.
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 to 5 / 4 / 0.02 V]
2301 Trans Current Adj
Adjusts the current applied to the transfer belt during copying.
Note: If this SP is too high, toner on the paper can go back to the drum.
