Frequently Asked Questions

Is the Q6511A on my cartridge label the same as the 11A?

Yes — they are two names for one cartridge. HP's packaging carries the 11A family name while the part number printed on the cartridge itself is Q6511A. If your old unit carries either marking, this 2-pack holds the cartridge your printer runs on.

Why do offices order this cartridge as a pair?

Because a printer that stops mid-week costs more than a cartridge on a shelf. With this $73.01 pair, one cartridge goes into the machine and the second waits sealed beside it, so the next change is a two-minute job instead of an emergency order.

Is each cartridge in the pack rated the same?

Each of the two Q6511A cartridges is individually rated at 6,000 pages, and each is sealed in its own bag and box inside the pack. You open them one at a time, months apart if that is how your printing runs — the second cartridge is not ageing on a countdown while the first works.

How should the spare cartridge be kept until it is needed?

Leave it in its sealed bag, flat in its box, in a dry cupboard away from direct sunlight and radiator heat. Stored that way, a toner cartridge keeps its quality for a long shelf life; toner does not dry out the way liquid ink can.

When the first cartridge fades, what is the routine?

Try the gentle rock first — tilt the cartridge side to side a few times to redistribute the toner and you may get a little more life from it. Once pages stay pale, swap in the shelf spare, and treat that moment as your reorder signal so the shelf is never empty for long.

What if one of the two cartridges turns out faulty?

Both are covered by the same 1-year warranty and 1-year free returns, whichever box the faulty unit came out of. Keep the order details handy, call us Monday–Friday, 9 AM–5 PM CST, and the cartridge is replaced or refunded.

About This 11A 2-Pack

This pack is built around a simple rhythm for a networked HP LaserJet 2420dn: one Q6511A working, one waiting. At $73.01 for two cartridges rated at 6,000 pages each, it removes the scramble that happens when a shared machine runs dry during a print run.

The pack ships from whichever of our IL, PA, GA or CA warehouses is nearest to you; the shipping & returns page covers the delivery details. More cartridges for this family are listed under HP.
