2220
Adjusts the TD sensor reference voltage (Vref). Change this value after replacing
the development unit with another development unit that contains toner.
[1.00 ~ 5.00 V / 4.00V / 0.01 step]
(1) Check the value of SP2-220 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, and then input the VREF for this unit into
SP2-220.
(3) After the test, put back the old development unit, and change SP2-220 back to
the original value.
