ABSTRACT:
An improved toner cartridge and contact which pertains to the recycling of the cartridge is disclosed by providing an alternate or additional way of completing the electrical bias connection to the magnetic feed roller by the addition of a simple contact, which is attached to a doctor blade, having a finger extending to ride onto the surface of the magnetic roller. This contact can be attached at either end, or both ends, of the doctor blade thereby connecting the doctor blade to the feed roller, the contact being held in place by the hold-down screws of the doctor blade.
