Turn your HP 5MP into an in-house bank-check printer with the HP 03A C3903A MICR toner cartridge from MICR Toner Mart. It lays down the magnetic (MICR) ink that bank scanners read along the routing and account line of your checks, so you print bank-ready checks yourself — no separate check printer needed. Yields approximately 4,000 pages. Each cartridge is custom-built and signal-tested for a strong, bank-accepted MICR line.
