The low-end color laser printer market has expanded rapidly in recent years. The design of small light-weight, high image quality, and low-cost color laser printers has been an issue. Authors have described a patented, magnet-less, removable toner cartridge in this article. This add-on low-cost cartridge can be designed such that it can be easily removed and replaced by a casual non-trained operator. Also, the replacement of the carrier in a dual-component development system can be easily accomplished in this way. These magnet-less cartridges can also be cost-effectively used in a single-component or a dual-component xerographic black & white printing, copying or faxing equipment. The architecture of color xerographic systems will be greatly simplified resulting in cost-savings and efficiency.

At this stage, we have demonstrated the feasibility of the magnetic brush and the magnet-less cartridge concepts. Our commercialization strategy calls for licensing the patents and additional knowledge of the office equipment manufacturers.
