Quick answer: A "non-genuine cartridge" message is the printer's firmware telling you it did not recognize the cartridge as the manufacturer's own. It is a notice, not a fault, and on most machines you dismiss it once and carry on printing. The one thing you usually give up is the ink or toner level gauge.
The message is designed to alarm you. It is worth knowing exactly what it is reporting, what it is not reporting, and which of the two situations you are actually in — because a small minority of these messages are a genuine hard stop, and those are handled differently.
What the printer is actually detecting
Most modern cartridges carry a small chip. When you close the door, the printer reads it and expects a response it recognizes: an identity for the cartridge type, and on many machines a counter the printer uses to estimate remaining level. If the response does not match what the firmware is looking for, you get the message.
Note what is not being tested. Nothing is measuring the toner, the ink, or the print quality. The check happens before a single page has been printed. It is an identity check, and it is the only thing that message reports.
The variants you will see
The wording differs by brand, but the categories do not:
| What it says, roughly | What it means | What to do |
|---|---|---|
| Non-genuine / non-original supply installed | Identity check did not match | Acknowledge and continue printing |
| Used or refilled cartridge installed | The chip's counter is not in the state a factory-fresh cartridge would be | Acknowledge and continue |
| Cannot determine supply level | The gauge has been switched off for this cartridge | Nothing to fix; watch print quality instead |
| Cartridge problem / supply not recognized, and the job will not run | A hard stop, not a warning | Reseat once, then treat it as a fault — see below |
What to do with the warning kind
- Read which of the four it is. If printing still works, it is a notice. If nothing prints at all, skip to the hard-stop section.
- Choose the "continue", "OK", or "yes" option when prompted. On some machines the prompt appears once per cartridge; on others it reappears after a power cycle.
- Expect the level gauge to stop being useful. This is the real trade-off, and it is worth planning around rather than fighting.
- Keep a spare on the shelf. Once the gauge is unreliable, a spare cartridge is what turns "out of toner" from an emergency into an inconvenience.
Living without the level gauge
In practice the printer tells you anyway, just later and more physically. Toner announces itself with fading down one side of the page, and a laser cartridge that is nearly spent can usually be rocked gently side to side to redistribute the powder for a few dozen more pages. Inkjets fade or drop a color. Neither failure mode is sudden, and neither damages anything.
Firmware updates: the one to get ahead of
Some manufacturers ship firmware that changes which cartridges a printer will accept. A cartridge that worked last month can stop being recognized after an automatic update, and the update usually installs quietly.
If you would rather control that, the setting lives in the printer's own configuration — its embedded web page (reachable from the printer's IP address), the control panel under a name like Web Services, Preferences, or Printer Update, or the manufacturer's desktop utility. Turning automatic firmware updates off, or switching them to "notify me", is easier to do while the machine is working than after a cartridge has stopped being accepted.
When it is a real problem
Treat it as a fault, not a message, if the printer refuses to print at all, throws a numeric error code, or reports the same cartridge as missing after you have reseated it once.
- Power the printer down fully, wait, and power it back up. This clears a surprising share of one-off read failures.
- Take the cartridge out and check the chip contacts are clean, undamaged, and that any protective tab or seal has been removed.
- Reseat it once, firmly, until it clicks.
- If it still will not run, stop there and contact us. A cartridge that a compatible printer will not accept is covered — see Warranty for what we do about it, or Returns & Refunds if you would rather send it back.
Please do not keep power-cycling or reseating past that point. If the cartridge is not being read, more attempts will not change the answer, and they use up time you could spend getting a replacement moving.
Which of our products even have a chip
Every product page states whether a chip is included, because it changes what you should expect on screen. As a rule of thumb:
- Toner and ink cartridges generally carry a chip, so a recognition message is possible. See Toner Cartridges and Ink Cartridges.
- Ink bottles for tank printers have no chip at all — there is nothing to authenticate, and no message.
- Drum units vary. Where a drum is a plain mechanical assembly there is no chip; where the printer counts drum life, there is. The listing says which: Drum Units.
Common questions
Does dismissing this message void my warranty?
No — and neither does using the cartridge. We go through the law on that in Do compatible cartridges void your printer warranty?
Will the message come back every time I print?
Usually not. Most machines ask once per cartridge; some ask again after a power cycle. A prompt on every single job is unusual and worth telling us about.
Can the level gauge be restored?
Not reliably, and we would rather say so than sell you a workaround. Plan for the gauge to be unavailable, keep a spare, and judge by output.
Is there a cartridge that never triggers this?
Bottles for tank-based printers, and any consumable with no chip in it. Beyond that it depends on the printer's firmware more than on the cartridge.
