Ink and toner cartridges are expensive enough that they've become a genuine, organized target for scammers — real industry figures from the Imaging Supplies Coalition, an alliance of printer manufacturers that tracks this specifically, put the counterfeit cartridge market at roughly $3.5 billion a year worldwide. Most of these scams follow a small number of recognizable patterns.
1. The "surprise invoice" scam
A business receives an invoice for toner or ink it never ordered. In a busy office, a convincing-looking bill for a routine supply item can slip through accounts payable without anyone double-checking it — especially if it references a real printer model the office actually uses (often gathered from an earlier "survey" call, see below).
2. The fake "technician" or "surveyor" call
Someone calls pretending to be a technician or conducting a routine survey, and asks for your printer's model number and account details. This pattern is common enough in the office-supply industry that it has its own name — "toner piracy" — and the gathered information is later used to make a follow-up scam call or invoice sound much more legitimate and specific.
3. "Too good to be true" pricing
A caller offers toner at an unusually low price — then either the quoted single-cartridge price turns into a large multi-pack charge, or what actually arrives is a cheap, counterfeit cartridge that leaks, jams, or simply fails within a few pages.
4. Pressure and urgency
A real supplier rarely needs you to decide in the next five minutes. Urgency ("your stock is almost out, act now") is a classic pressure tactic scammers use before you've had a chance to verify anything against your own actual purchase records.
5. Look-alike company names
Some scam operations use a name that sounds almost identical to a real, well-known supplier — close enough that a quick glance doesn't catch the difference, especially over the phone.
How to protect yourself
- If someone calls unprompted offering to sell you toner, treat it as a scam until proven otherwise.
- Never confirm your printer's exact model or account number to an unsolicited caller.
- If a caller claims to be your regular supplier, hang up and call the supplier back on their known, official number — not one the caller gives you.
- Check any unfamiliar invoice against your own purchase records before paying it.
- Inspect any cartridge that does arrive for leaking, poor print quality, or obviously low-quality packaging (see our companion piece on spotting a counterfeit cartridge).
- In the US, a suspected scam can be reported directly to the Federal Trade Commission.
Why small businesses are targeted more than individuals
Scammers specifically favor small offices over individual consumers, for a simple structural reason: a small business typically has one person handling purchasing across many categories, not a dedicated procurement team that would recognize an unfamiliar vendor immediately. A busy front-desk employee who isn't the one who normally orders supplies is exactly the target these calls are designed for — which is why the fix isn't "be smarter," it's building a habit of always routing unexpected supply calls or invoices back to whoever actually manages that relationship, every time, no exceptions.
What a legitimate supplier call actually sounds like
A genuine account manager already knows your account number, your order history, and your contract terms without needing you to read anything off your own printer — because they're the ones with the records, not you. If a caller needs YOU to supply identifying details before they can tell you anything about "your account," that's already backwards from how a real existing business relationship works.
