Product purpose

This MICR toner cartridge is built for businesses that print their own cheques and need magnetic ink character recognition for bank processing. It replaces the HP CE390X cartridge and fits the listed LaserJet Enterprise 600 M602, M603 and M4555 MFP models.

Who should buy and who should not

Offices that require secure cheque printing on compatible HP LaserJet Enterprise printers will meet banking standards with this cartridge. It is not for users who print only standard documents and do not need MICR toner, nor for printers outside the specified Enterprise 600 and M4555 series.

Capacity and headroom

The cartridge yields approximately 24000 pages at five percent coverage, supporting high-volume cheque runs without frequent changes. Very heavy daily workloads will exhaust the toner sooner, requiring replacement to maintain MICR print quality.

Questions about this item

Which printer must I already own for this MICRTHN90X cartridge to work?

The cartridge fits HP LaserJet Enterprise 600 M602, M603 and M4555 MFP series printers, plus the Troy MICR 602, 603 and 8000 Secure models.

How will the cartridge behave alongside the standard HP CE390X toner I still use for everyday printing?

It replaces the CE390X directly and prints magnetic MICR characters for checks while the standard toner handles normal documents; both yield up to 24000 pages at 5 percent coverage.

How can I verify the cartridge is working as intended after installation?

Print a check and confirm the bottom line shows clear magnetic MICR characters that a bank reader can capture.
