Remanufactured cartridges are different from recycled or refilled cartridges, commonly referred to as, "drill and fill." Drill and fill operations merely top off empty cartridges, but do not check critical components such as drums, gears and wipers. A remanufactured cartridges on the other hand, are completely disassembled, worn out parts are discarded and then remanufactured like a new unit. Some of the critical aspects of the remanufacturing process that ensure that they perform as well as OEM are as follows. Unused toner in old cartridges is discarded. Toner that was not used in a cartridge are particles that were not able hold an electrostatic charge and would be useless. Drums are resurfaced and refinished to eliminate blemishes and give it a renewed magnetic surface. It is the drum that transfers toner to paper so it is the most critical element to image quality.
