Disclosed is a printing system employing a Magnetic Ink Character Recognition (MICR) toner developer housing, and a non-MICR toner developer housing, and which system affords high quality, low cost MICR and optionally non-MICR documents. The system is capable of producing either or both MICR and non-MICR documents. For example, the system prints a MICR readable line with only a MICR toner developer whereas the remainder of the document is printed with a significantly lower cost non-MICR toner developer. Advantages of the system include: an ability to produce MICR documents of the highest quality, that is, the MICR line printed with the MICR toner ensures high fidelity of magnetic properties required thereof, whereas the non-MICR areas are printed with non-MICR developer to provide superior print quality which is not necessarily always obtainable when non-MICR line areas of the document are printed with MICR type developers. Another signifcant advantage provided by the present system is the ability to provide sigmfkant cost reductions in the price per impression formed thereby. The proposed system does not require precise registration of the MICR and non-MICR developer housings, particularly where the developer housings are configured in tandem, for example, in a single pass xerographic process.
