MICR toner for Lexmark MS4

The microMICR Corporation MICR-TLN-551 is a monochrome toner cartridge engineered for the Lexmark MS4 printer. It is designed for businesses and financial institutions that require magnetic ink character recognition for cheque printing and secure document handling. This cartridge supplies the specialised MICR toner formulation needed for automated clearing systems.

Direct replacement installs in seconds

The cartridge fits the Lexmark MS4 exactly like the original 55b1000 unit, so no tools or firmware steps are required. The only common issue is forgetting to remove the sealing tape before insertion, which can cause blank pages on the first print run. Ensure the printer is powered on and the front cover is fully closed after installation.

Monochrome MICR yield matches 551 reference

The single specification that decides fit is the monochrome MICR toner type matched to the Lexmark MS4 platform. If your workflow demands standard colour or non-MICR black toner, this cartridge will not meet that requirement. Buyers needing high-capacity colour output or non-magnetic black ink should select a different product.
