Compatible MICR Cartridge

The SuppliesMax HP C3909A-MICR compatible toner cartridge delivers magnetic ink character recognition output for secure check and barcode printing. It replaces the HP C3909A-MICR original and fits a wide range of HP LaserJet 5si, 8000 and Mopier 240 models as well as Troy MICR 524, 5si, 624 and 8000 devices.

Build Fit and Yield

The single black cartridge installs directly into supported 110V U.S.-based printers without hardware changes. It yields up to 15000 pages at 5% coverage, freeing high-volume environments from frequent replacements while maintaining bank-compliant print quality.

Sustained Load Behaviour

Magnetic toner formulation is engineered for consistent density across long print runs, reducing the risk of read errors on financial documents. Manufactured to OEM specifications, the cartridge maintains sharp output over its full rated life rather than fading after a short burst.

Questions about this item

Will the 15000-page yield hold up during continuous check-printing runs?

The cartridge is rated for 15000 pages at 5% coverage; sustained high-coverage check printing will reduce the actual page count.

Does the magnetic toner generate extra heat or fan noise in an HP LaserJet 8000 during all-day operation?

The toner is engineered to OEM specifications for the 110V LaserJet 8000 series, so heat and acoustic levels match the printer's normal profile.

Which printer models must I already own for this C3909A-MICR cartridge to work?

It fits HP LaserJet 5si, 5si Mopier, 5si Mx, 5si Nx, 8000, 8000DN, 8000N, 8000-MFP, Mopier 240 and Troy MICR 524, 5si, 624, 8000 printers.
