SuppliesMax MICR Toner Cartridge

The SuppliesMax MICR Toner Cartridge is a compatible replacement for Lexmark E250A21A-MICR and several equivalent OEM part numbers. It delivers up to 3500 pages at 5% coverage and is engineered for bank-compliant check and barcode printing. The cartridge is manufactured to OEM specifications and designed for use in supported 110V U.S.-based printers. It comes new in a single pack with black magnetic toner.

Upgrade from standard toner for MICR needs

This cartridge replaces a standard black toner when magnetic ink character recognition is required for secure financial documents. The jump is worth it for businesses that print cheques or barcodes and must meet banking standards for readability and fraud prevention. It fits the same Lexmark E250, E350 and E352 series printers as the original E250A21A-MICR cartridge. No hardware changes are needed beyond swapping the cartridge.

Suits offices printing cheques and barcodes

This product suits offices and organisations that produce cheques, drafts or MICR-encoded documents on compatible Lexmark laser printers. It is not for users who only need standard black text printing and do not require magnetic toner. Buyers with printers outside the listed Lexmark E250, E350 or E352 series should verify compatibility before purchase. Those needing colour output or higher page yields must look elsewhere.
