SuppliesMax Sindoh SMF4525K-MICR MICR High Yield Toner Cartridge 25000 Pages

MICR Toner for Secure Check Printing

This SuppliesMax cartridge supplies magnetic toner formulated for bank-compliant MICR output on the Sindoh MF-4550H. It replaces the OEM SMF4525K-MICR and yields up to 25000 pages at .05 coverage. The product is built in ISO 9001 and ISO 14001 certified facilities using new and recycled components. It is engineered for 110V U.S.-based printers and carries a 30 day manufacturer warranty.

Practical Limits of Aftermarket MICR Cartridges

Magnetic toner must meet strict signal standards for cheque clearing, so print density and particle consistency are critical. Aftermarket formulations are validated against OEM specifications, but batch variation can affect read rates on high-speed sorters. The cartridge is rated for 25000 pages at standard coverage; heavy graphics or dense forms will reduce actual yield. Compatibility is confirmed only for the Sindoh MF-4550H and the listed OEM part number.

Upgrade from Standard Black Toner

Standard black toner lacks the magnetic oxide required for MICR encoding, so it cannot produce machine-readable cheques. This cartridge adds that capability while matching the 25000 page yield of the high-yield OEM unit. The jump is worthwhile when a business prints its own cheques or barcodes and needs bank-accepted output without buying a dedicated MICR printer. It is not for users who only print general documents and have no MICR requirement.
