Change this value after replacing thedevelopment unit with another one thatalready contains toner.For example, when using a developmentunit from another machine for testpurposes, do the following:1. Check the value of SP2-220 in both themachine containing the test unit and themachine that you are going to move it to.2. Install the test development unit, theninput the VREF for this unit into SP2-220.3. After the test, put back the olddevelopment unit, and change SP2-220back to the original value.
