MicroMICR takes brand new original equipment manufacturer cartridges and replaces the regular toner with special Magic Ink Character Recognition toner which is specially made for encoding checks. The iron oxide in the toner allows the magic reader sorter at your bank to read the symbols at the bottom of the check. Printing your own encoded checks saves you the expense of ordering pre-encoded checks. All you need is the MICR toner blank check stock and the MICR font installed on your printer.Primary InformationProduct Type : Toner cartridge Printer Technology : Laser Output Color : Black Compatibility : DocuPrint N40 DocuPrint N24 DocuPrint N3225 DocuPrint N32 DocuPrint N4025 Yield : 23000 pages at 5% area coverage UNSPSC CodeUNSPSC Code : 44103103
