Buying cartridges goes wrong in one specific place: the moment you have to turn "the printer in the corner" into a part number. Everything below exists to take that step off you.
Step 1 — Tell us your printer, once
There are three ways in, and they all end in the same place:
- Pick it from a list. Brand, then series, then model. Use Find your printer.
- Type the model number. Whatever is printed on the front of the machine — LaserJet Pro M404dn, PIXMA TS3320, EcoTank ET-2800. Partial is fine.
- Search the cartridge number if you already know it — CF248A, 245XL, TN760. The Compatibility Guide explains where to find that number if you do not.
Your choice is remembered as you browse, so you only do this once. A thin bar at the top of the site shows which printer you are shopping for, and you can change or clear it at any time. Nothing about it is required to check out — it just stops the site showing you cartridges you cannot use.
Step 2 — We cut the catalog down to what fits
Once we know the printer, the site stops being a catalog and starts being a short list.
Every listing tells you where it stands
Green means this item fits your printer. Red means it does not, and links you to the ones that do. There is no third state where we let you guess.
You still choose the things that are genuinely a choice
- Color — black on its own, a single color, or the full set.
- Yield — standard or XL. Same cartridge shell, more toner or ink inside. XL is nearly always cheaper per page; it is only the wrong call if the cartridge will dry out or go obsolete before you finish it.
- Pack size — one, two or four.
Each variant carries its own page yield and its own OEM comparison price, so the saving you see is the saving for the exact thing in your cart.
The awkward details are on the page, not hidden
Whether a chip is included, how many pages the ISO standard measured, which printers the item fits in full. If something about an item is a compromise, it is written on the item.
Step 3 — Install it in about a minute
Toner and ink are designed to be swapped by whoever owns the printer, without tools. Pull the old one, unwrap the new one, seat it until it clicks. The installation guides cover toner cartridges, ink cartridges, drum units and maintenance boxes, plus what to do in the one case that actually trips people up — a printer that refuses to recognize a brand new cartridge.
When you are done, the empty box is not trash. See Recycling.
What happens if it still does not fit
Occasionally we get it wrong, or a printer turns out to have a variant we did not know about. In that case the return shipping is on us and you get a full refund — that is not a goodwill gesture, it is written into the Return Policy. Faults that show up later are covered for two years under the Warranty, including damage a cartridge of ours does to your printer.
Where the savings actually come from
Not from less ink. From not paying for the printer twice. We compare against the manufacturer's own price for the equivalent cartridge and show the yield both were measured at, so you can check the per-page math yourself rather than trust a percentage. The basis for those comparisons is stated in our Terms of Service.
