Developer material | Toshiba FC-22 specification

(b)Cleaning every 60K (which should be give priority when coincides with every-30K cleaning)

Note: This cleaning should be done subsequent to “automatic removing of developer material”.

(1)Move the developer removal shutter lever in

the direction of the arrow shown to close the developer removal opening.

(2) Remove the developer unit from the EPU.

(3)Remove the developer unit cover. Insert the

doctor blade cleaning jig between the doctor blade and the sleeve and move the jig back and forth; make 3 return movements to clean the doctor blade.

(4)After the cleaning, return the developer re- moval shutter lever to open the developer re-

moval opening (move the lever in a direction reverse to (1)).

(5)Making the developer removal opening point

downward, remove the developer material re- maining in the developer unit. (Shake the de- veloper unit to the right and left, and rotate the mixer and the sleeve alternately.)
