1. Cleaning
Clean the doctor blade so as to prevent developer material from adhering to it when the drum
is being replaced.
Space the front shield from the developer sleeve and then insert a doctor blade cleaning jig
into the doctor sleeve gap. Then clean the doctor blade by running the jig for 3 times to and
fro along with the edge of the blade.
