SuppliesMax Unisys MICR Toner Cartridge

The SuppliesMax Unisys 81-6304-978-MICR is a compatible black toner cartridge built for high-volume check printing. It delivers up to 15000 pages at .05 coverage using magnetic toner formulated for bank-compliant MICR output. The cartridge replaces the Unisys OEM equivalent and is manufactured in ISO 9001 and ISO 14001 certified facilities. It is engineered for reliable performance in supported 110V U.S.-based laser printers.

Check Printer Model and Voltage Before Ordering

Verify that your printer is a Unisys UDS-630MRN, UDS-630-N11, UDS-635MRN or UDS-635-N11 before purchase. This cartridge is designed for 110V machines sold in the U.S. and will not function correctly in other voltage environments. Confirm the OEM part number 81-6304-978-MICR matches your current supply to ensure proper fit. Buyers who need toner for non-MICR printing or different printer models cannot use this cartridge.

Sustained High-Yield Check Printing Performance

Magnetic toner maintains consistent signal strength across the full 15000-page yield for secure check and barcode processing. The formulation resists density drift during long print runs, keeping MICR read rates within banking standards. Components are built to OEM specifications to prevent premature wear during continuous operation. Users who require colour output or standard non-magnetic toner will not be served by this product.
