ABSTRACT:
An apparatus and method for providing a removable closure seal between the toner hopper and the toner feed roller compartment of a toner cartridge assembly used in printers, copy machines and facsimile machines. The seal prevents toner from leaking from the toner hopper into the feed roller compartment during shipping and handling. In one embodiment, the seal has a slotted seal insert placed over the passage between the hopper and roller compartment. A removable tape closes the slot. In another embodiment, a slotted seal insert is slid between grooves in the toner cartridge assembly into position between the hopper and feed roller compartment. The insert is attached to the cartridge assembly by glue, tape, or other adhesive. An insert tool is used to facillitate this attachment. A reusable, removable closure seal is slid between the grooves to close the slot. The closure seal may have a metal spine to increase its rigidity. A crush-resistant velvet material with a foam backing is used to improve the seals at the ends of the feed roller compartment.
