Our MICR formulations are tuned for consistent E-13B signal strength and clean character edges, helping reduce rejects at the bank when used with proper check stock and layouts. Every batch is quality-checked so you can run payroll or AP with confidence.

Look up your exact model (e.g., ST9730, ST9612, ST9800), then match the MICR part number on our product pages. If you’re unsure, message us your printer model and volume—we’ll recommend the precise OEM or premium compatible option (and high-yield if it fits your usage).

Yes: 1) Install the cartridge carefully—don’t touch the developer/drum surface. 2) Run density/calibration, then print a test check to verify MICR line placement and darkness. 3) Use compatible check stock and allow a short cure time before stacking or folding.
