Purpose-built MICR toner

This microMICR THN81A cartridge prints 10500 pages of black MICR output for cheque processing. It replaces the HP 81A (CF281A) and is designed for LaserJet M604, M605, M606 and M630 series printers. Financial offices and service bureaus use it to meet banking readability standards.

Verify printer model first

Confirm the exact model number on your device matches the supported M604, M605, M606 or M630 series listed in the specifications. MICR toner is formulated differently from standard toner, so ensure your workflow requires magnetic ink character recognition before installing this cartridge.

Consistent yield across long runs

The 10500-page rating reflects sustained printing under typical office coverage rather than a short burst. MICR formulation maintains signal strength for reader-sorters throughout the cartridge life, reducing rejections on high-volume cheque batches.

Questions about this item

Does the THN81A box contain only the black toner cartridge or are drums or waste bins included?

The box contains one black toner cartridge only; drums, waste bins or other supplies are not included and must be purchased separately if required.

How do I decide between the THN81A and a high-yield alternative for my HP LaserJet M605dn?

The THN81A is a standard-yield cartridge rated at 10500 pages; if your print volume regularly exceeds that figure a high-yield version would reduce change frequency.

Will the 10500-page yield hold up when printing dense MICR cheque batches on an M606x?

The 10500-page figure follows industry standard coverage; dense MICR cheque runs use more toner per page so the actual count will be lower.
