ABSTRACT:
The present invention is a device for separating a toner cartridge hopper from its mounting member so that the cartridge can be reliably resealed and refilled with toner for repeated use. A container holds the cartridge while leaving the outer edge of the gasket exposed. In one embodiment, the container is provided with wheels that travel in a track. The container moves linearly along the track past a blade that cuts away the outer edge of the gasket. In a second embodiment, the container is positioned on a rail aligned to pass between two spaced-apart blades. The rail is mounted on a linear bearing so that the rail moves linearly past the blades to remove both gasket outer edges in a single pass. By removing the outer edges of the gasket, the welds that join the hopper and mounting member to the gasket are broken and the hopper can be separated from the mounting member.
