Abstract

In order to transfer toner from a cartridge 10 to a sump 12 without opening either to the surrounding environment and thus avoiding the risk of dropping the open cartridge, a rectangular closed slide 14 and a foam seal 16 are visualized. As shown, the sump also has a rectangular closure slide 18 with a lip, a seal 17 to close off the toner chamber, a recess 20 and a seal 21 for docking the cartridge and detents 15 to capture it. In operation, the cartridge 10 would be inserted into the sump recess 20 and held against seal 21 by detents 15. The cartridge closure slide 14 would nest into the sump closure slide 18, being captured by the molded lip of the sump closure.

TONER CARTRIDGE (Cont'd)

Molded into the underside of the sump closure slide would be a rack feature 22.
This would be actuated by a molded gear segment 24 mounted on its own plastic shaft 26 that would be rotated by an external lever 28.

Actuating the external lever 28 would move the sump closure slide 18 away from the opening it covers. Because the cartridge closure slide 14 is captured by the sump closure slide 18, actuation of the lever would move both closure slides together opening both containers simultaneously and allowing the toner to pour into the sump.

Actuating the lever 28 to the closed p...
