Frequently Asked Questions

Which cartridge is this, in the codes a purchase order uses?

It is the Q5942A, the cartridge HP also lists under the short name 42A. Both codes describe the same black cartridge, so a reorder sheet written either way points at this box. It is a single cartridge at $51.26, rated at 10,000 pages.

How long should one cartridge last in the base 4250?

The rating is 10,000 pages at 5% coverage, and the LaserJet 4250 is a steady workgroup printer rather than a personal one, so most offices measure that life in weeks of shared printing. Dense pages — forms with heavy rules and logos — shorten it; plain text stretches it.

Print is turning gray in patches. Is the cartridge empty?

Usually not yet. Toner settles as the cartridge nears its end, and rocking the cartridge gently side to side redistributes what is left so coverage evens out again. Treat it as a warning to order, not as the end — the fade returns once the remaining toner is truly spent.

Can the printer itself tell me how much is left?

Yes. The supplies status page, printed from the control panel menus, reports an estimated remaining percentage for the Q5942A alongside page counts. It is an estimate rather than a gauge, but it is reliable enough to time a reorder before the fade starts.

How should a spare be kept until it is needed?

Sealed in its box, lying flat, out of direct sunlight and away from heat sources. A cartridge stored that way is ready the moment the installed one fades mid-job, which is the whole point of keeping one on the shelf.

What cover does the purchase include?

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 is staffed Monday–Friday, 9 AM–5 PM CST.

About This Q5942A Cartridge for the LaserJet 4250

The base 4250 is the anchor of its family — a plain, durable workgroup machine that offices keep for years because it asks so little of them. Its cartridge should match that character: a standard 42A at $51.26 in our HP range, fitted in minutes and forgotten about for the next 10,000 pages.

Nothing about the swap is specialized. Open the top cover, slide the old cartridge out by its handle, seat the new one until it clicks, and the printer is back in service before the queue notices.
