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.
