Serial Numbers and Soggy Pages: Vetting an Ink Bargain Before It Reaches Your Doorstep

Nobody sets out to buy counterfeit ink. You see a cartridge at roughly two-thirds of the price you expected, the listing photo looks like the real thing, the seller has a decent star rating, and you click. That's the whole trick — fakes don't survive on gullibility, they survive on busy people doing a quick shop on a phone at half nine at night.

The good news is that a few minutes of checking catches most of them. Not all, but most. Here's the routine.

Start with the boring truth

Plenty of cheap cartridges are perfectly legitimate. Compatible and remanufactured ink is a normal, lawful part of the UK market, and a low price on its own proves nothing. What you're looking for isn't "cheap", it's inconsistent — a price that doesn't match the seller, the packaging that doesn't match the brand, or a story that doesn't hold together. Keep that distinction in your head and you'll avoid both fakes and the low-level panic that makes people overpay at the till.

The price that makes you blink

Genuine branded cartridges have a fairly narrow price band across UK retailers. If a listing is dramatically under everyone else — not 10% under, more like 50% — ask yourself what the seller knows that Tesco, Argos and your local stationer don't. Sometimes it's grey imports, sometimes it's short-dated stock, sometimes it's a bulk-buy reseller with thin margins. And sometimes it's a box of something that isn't what the label says.

A useful sanity check: work out the cost per page. Fakes are often sold as high-yield XL cartridges at a standard-yield price. If the numbers look too generous, treat it as a question rather than a verdict.

Five minutes of seller homework

Before you pay, look at the seller rather than the product.

• Age and history. A marketplace account opened eight weeks ago with 400 reviews is worth a second look. Long-established sellers with mixed but human-looking feedback are usually safer.
• What else they sell. A shop that stocks cartridges alongside phone cases, kitchen gadgets and dog toys may be a general reseller. Not automatically bad, but less accountable than a specialist.
• The reviews that aren't five stars. Scroll past the top ones. Look for repeated mentions of smudged printing, cartridges "not recognised", or packaging that arrived opened.
• Contact details. A UK trading address and a phone number you can actually find is a decent signal. A listing with none at all is a weaker one.
• Where the ad came from. Social media ads for ink are a common route for counterfeits in 2026. Treat a sponsored post with the same suspicion you'd give a stranger in a car park.

The box in your hands

If you buy in person, or once the parcel arrives, the packaging does a lot of talking.

Genuine branded boxes are printed to a high standard: crisp text, consistent colour, no fuzzy edges on the logo. Fakes tend to slip on the details — slightly off brand colours, wonky alignment, thin cardboard, spelling mistakes in the small print, a hologram that's just shiny foil rather than a proper changing image. Check the security seal: it should be intact, and it should be difficult to peel and reapply without leaving evidence.

Also read the batch and expiry information. Real cartridges carry it. Fakes often carry something that looks like it, printed slightly crooked in a font that doesn't match the rest of the box.

The cartridge itself

Pull it out and look closely.

• The label should be clean, straight and legible.
• The plastic shouldn't feel brittle or rough along the seams.
• Genuine cartridges usually have a small amount of protective tape that peels cleanly; fakes sometimes use a cheaper film that leaves residue.
• If the cartridge is meant to be new, there should be no sign of refilling — dried ink around the fill hole, a slightly discoloured sponge, or a reset chip that looks recently handled.

Serial numbers and chips

Most major manufacturers print a serial or batch code on the box and on the cartridge, and some offer an online verification tool. Use it if it exists — but don't panic if it doesn't. A serial number that doesn't match between box and cartridge is a genuine red flag. So is a chip that your printer refuses to recognise on a supposedly genuine cartridge, especially when the seller blames your printer.

One caveat: modern printers can reject legitimate third-party cartridges too, usually because of a firmware update rather than a forgery. If the listing said "genuine" and the chip won't talk to your printer, that's a conversation to have with the seller either way.

If it's already in the printer

The first page tells you a lot. Genuine ink in good condition prints cleanly. A fake might deliver streaky bands, colour that looks muddy next to your last print, or nozzles that clog within a week. Run a test page and compare it to something you printed before. Keep the box, the receipt and the packaging until you're satisfied — without them, a return gets much harder.

If a fake slips through

Don't bin it and don't shrug. In the UK you have proper routes:

1. Message the seller first, in writing, through the platform. Ask for a refund and say plainly that you believe the item is counterfeit.
2. Escalate to the marketplace if the seller stalls. Most have a counterfeit reporting process and will expect photos of the packaging, the cartridge and the serial numbers.
3. If you paid by card, remember Section 75 for purchases over £100 and chargeback for smaller amounts through your bank.
4. Report it. Trading Standards takes counterfeit goods reports via Citizens Advice, and manufacturers generally want to know about fakes carrying their name.

Keep it factual. "This cartridge is counterfeit because the serial number on the box doesn't match the cartridge, and the printer rejected the chip" lands better than a paragraph of fury.

The unglamorous conclusion

You don't need to become an ink detective. Buy from sellers with a traceable UK presence, be suspicious of prices that don't fit, check the seal when the parcel lands, and keep your paperwork for a fortnight. That's it. Boring, quick, and it's the difference between a bargain and a soggy test page.
