Replacing The Developing Unit
CAUTION Do not replace the developing unit unless you have been
trained to do so. Be careful not to damage the sensors while
cleaning the developing unit. (If damage occurs, contact your
service representative.)
Removal
1. Turn the power switch OFF.
2. Open the printer upper doors. (See page 109.)
3. Open the waste toner recovery unit. (See page 113.)
4. Rotate the developing unit lever fully clockwise so that it is
pointing straight up. This separates the developing unit from
the photoreceptor drum.
