ABSTRACT:
A type 2 IP-5000 toner cartridge is converted to a type 1 HP-5000 toner cartridge. The device and method are utilized by placing a repair contact over-plate over a double-spring contact subassembly to make a flat surface for the coil-spring contactor to engage while it rotates so that there will be electrical communication between the double-spring contact subassembly, the repair contact over-plate, the coil-spring contactor, the flange and the developer roller. The repair contact over-plate has at least two attachment-alignment holes used to lock into posts of the gear housing. Various forms of locking, removable locking or non-locking may be implemented into the repair contact over-plate. Installation of the repair contact over-plate may be facilitated by using a tool. The tool may consist of one plate, bar or flat srewdriver with at least one attachment-alignment hole to press the repair contact over-plate over the posts.
