Compatible HP Q5942A Toner Cartridge Black MICR HP 42A Toner produce superior quality and consistency for a wide array of printing needs
HP Q5942A Toner Cartridge Black MICR HP 42A Toner is designed to deliver the best image quality and reliable printing. Toner cartridge is compatible with HP LaserJet 4240 4250 4350 printer series and yields up to 10000 pages.
Features:
The toner. This is the MICR version of the 42A: its toner is magnetic, formulated so the account and routing characters along the bottom of a cheque can be read by bank sorting equipment. In every other respect — fit, handling, the 10,000-page rating — it behaves as the family cartridge for machines such as the LaserJet 4240 and the 4250/4350 series.
Yes. MICR toner prints normal text perfectly well, and many small offices run one cartridge for both cheques and correspondence rather than swapping. The premium — $153.59 for this single — is paid for the magnetic formulation, so heavy cheque volume is what justifies it.
That depends on the whole print chain, not the cartridge alone: cheque stock, character placement and printer condition all feed the reader's verdict. We therefore cannot promise any bank's acceptance. Print test cheques on your actual stock and have your bank verify a sample before a live run — that check, done once, is the professional way to start.
Weak signal from a cartridge at the very end of its life, or characters drifting out of position. Keeping the MICR cartridge reasonably fresh, and re-verifying after any printer service, removes most of the risk that sits within your control.
Keep the cartridge sealed until fitting, as with any toner — and treat printed cheque stock with the same care you would the cartridge: it is a financial instrument from the moment the MICR line lands on it.
A 1-year warranty and 1-year free returns, set out on our shipping & returns page. Orders ship from warehouses in IL, PA, GA, and CA, and support runs Monday–Friday, 9 AM–5 PM CST.
Cheque printing is the one job in the office where the reader is a machine at a bank, not a person at a desk — which is why this specialised version of the 42A exists in our HP range. Payroll and accounts-payable runs on a 4250 or 4350 are its natural home.
The cartridge asks for one habit ordinary toner does not: verify before you rely. A short test batch, confirmed with your bank, converts MICR from a hope into a procedure — and after that, it is simply the cartridge you fit when cheques are on the schedule.
It is little costly but Producing nice prints which is very important for work.
Long lasting but not sure how to find the same product again. I purchased some others that were identical and they didn't last nearly as long as it.
