The energization of SL6 (occur when MSS is "ON" and density is low) results in plunger
and lever movements as depicted by the black arrows in Fig. 4-43.
The white arrows re-
present the motion as the components return to their normal positions when SL6 turns
"OFF".
The above mentioned lever motions result in the upward pivot action of the toner valve
trip lever to release concentrated toner into the Developer Assembly. The toner valve ac-
tuated is part of the cap of the concentrated toner bottle mounted on the front end of the
Developer Assembly. Fig. 4-44 depicts these actions.
