"Non-HP Chip Detected" on Your HP Printer: What It Means and What to Do

Quick answer: "Non-HP Chip Detected" means your HP printer read the cartridge's chip and decided it isn't an HP chip. On printers with HP dynamic security, that can block printing, and a firmware update can make a cartridge that worked yesterday stop working today. First reseat the cartridge and power-reset the printer. If it's a compatible cartridge, turn off automatic firmware updates and contact the seller for a replacement with an updated chip. If it's a genuine HP cartridge, it may be counterfeit or faulty; HP's anti-counterfeit team can check it.

Key Takeaways

• The message appears when an HP printer reads a cartridge chip it doesn't recognize as HP's, on both LaserJet and OfficeJet/ENVY models.
• HP says printers with dynamic security are designed to work with cartridges that have a new or reused HP chip, and firmware updates can block cartridges that previously worked.
• Turn off automatic firmware updates before installing compatible cartridges; it's the single most effective prevention.
• HP+ printers (models ending in "e" with HP+ activated) are locked to Original HP supplies; compatible cartridges are not an option there.
• Using non-HP supplies does not by itself void your warranty under U.S. law, though HP can charge for repairs it attributes to a third-party cartridge.

What Does "Non-HP Chip Detected" Mean?

It means the printer checked the small electronic chip on your ink or toner cartridge and concluded the chip isn't made by HP. Every modern HP cartridge has a chip that reports the cartridge type and ink or toner level. Many compatible and remanufactured cartridges use a third-party chip, and HP printers can detect that.

What happens next depends on the printer. On some models it's a warning you can acknowledge and keep printing. On printers with dynamic security, the cartridge can be blocked and the printer won't print with it. You may also see related messages such as "Supply Problem," "Cartridge Problem," "Incompatible cartridge" or a note that a used or counterfeit cartridge is installed.

Why Did My Printer Suddenly Say "Non-HP Chip Detected"?

If the same cartridge printed fine before, a firmware update is the most likely cause. HP states that firmware updates delivered over the internet keep its cartridge security measures effective and may block cartridges that previously worked. Printers are often set to install updates automatically, so the change can happen overnight without you noticing.

HP's dynamic security has been part of its firmware since 2016, and it has prompted repeated complaints and lawsuits from owners. We cover the background in printer firmware updates and third-party ink and the 2026 HP firmware lawsuits.

How Do I Fix "Non-HP Chip Detected"?

Start with the free mechanical fixes, because a dirty or poorly seated chip can trigger the same message as a rejected one. Then deal with the firmware side.

1. Reseat the cartridge. Remove it, check that all packing tape and the protective strip are gone, and push it back in firmly until it clicks. HP's support replies list improper seating as one cause of this message.
2. Clean the chip contacts. Gently wipe the cartridge chip and the printer's contacts with a lint-free cloth. Don't touch them with your fingers afterward.
3. Power-reset the printer. With it on, unplug the power cord for 60 seconds, then plug it straight into a wall outlet. See how to reset an HP printer.
4. Try another cartridge from the same pack. If only one is rejected, that chip may be faulty.
5. Turn off automatic firmware updates so the situation doesn't get worse (steps below).
6. Contact the seller. Reputable compatible brands release cartridges with updated chips after HP firmware changes and will replace a cartridge your printer refuses.
7. If it's a genuine HP cartridge, HP's LaserJet documentation directs you to hp.com/go/anticounterfeit to confirm it's authentic.

How Do I Turn Off Automatic Firmware Updates on an HP Printer?

Change the printer's update setting to "Do not check" or "Notify only" from the control panel, the Embedded Web Server, or HP Smart. The exact labels vary by model:

• Control panel: Setup (or Settings) > Printer Maintenance or Tools > Update the Printer > Printer Update Options, then choose not to install updates automatically.
• Embedded Web Server: type the printer's IP address into a browser, open Tools > Product Updates (or Firmware Update), and turn off automatic updates. Need the IP? See how to find your printer's IP address.
• HP Smart app: open your printer's Printer Settings > Advanced Settings and disable automatic updates.

What Is HP Dynamic Security?

Dynamic security is HP's name for firmware that checks cartridge chips and blocks cartridges with non-HP chips or circuitry. HP's own LaserJet guide says these printers are designed to work with cartridges that have a new or reused HP chip, block cartridges with a non-HP chip, and can receive updates that keep those measures effective. HP labels affected products as "dynamic security enabled" in its product documentation.

Not every HP printer has it, and policies have shifted over the years. Some older OfficeJet Pro models received firmware that removed dynamic security, while newer models ship with it. If you're choosing a printer for low-cost ink, read which printers work best with compatible ink.

What Is HP Cartridge Protection?

HP Cartridge Protection is a separate setting. When it's on, the printer "marries" HP cartridges to that one printer so they can't be used in another. It's about theft and reuse, not chips, and it can be turned off in the printer's settings or Embedded Web Server on models that offer it. It doesn't cause "Non-HP Chip Detected."

Does "Non-HP Chip Detected" Happen on HP LaserJet Printers?

Yes. It's common on LaserJet Pro and Color LaserJet Pro models, including the M254dw and the current Color LaserJet Pro 4201 and MFP 4301 series that use HP 210A/210X toner. On those models the message can block printing rather than being a warning you can dismiss. That's why we tell buyers of our HP 210X compatible toner to switch off automatic updates before installing. HP's LaserJet documentation also notes that the control panel or the supplies status page flags a non-HP cartridge.

Will Using Non-HP Ink or Toner Void My Warranty?

No, not by itself. In the U.S., the Magnuson-Moss Warranty Act bars a manufacturer from voiding a warranty just because you used another brand of supplies. HP's own policy says the same: using a non-HP cartridge doesn't affect your warranty or support contract, but if a failure is attributed to a non-HP or refilled cartridge, HP charges its standard rates for that repair.

Can I Bypass "Non-HP Chip Detected"?

Sometimes, depending on the model and firmware. Where the message is only a warning, pressing OK or Continue keeps printing. Where dynamic security blocks the cartridge, the realistic options are a replacement cartridge with an updated chip, an older firmware version if HP still offers one for your model, or Original HP supplies. We don't recommend unofficial firmware hacks; they can brick the printer. See HP printer not recognizing ink cartridge? How to fix (and bypass) cartridge errors.

Frequently Asked Questions

Is "Non-HP Chip Detected" the same as a counterfeit warning?

Not exactly. The chip message means the chip isn't HP's. A counterfeit warning means the printer suspects a cartridge sold as genuine HP isn't. Both can come from the same chip check.

Why does a genuine HP cartridge say Non-HP chip?

Usually poor contact, a damaged chip, or a counterfeit sold as genuine. Reseat it and clean the contacts; if it persists, report it to HP and the retailer.

Will a firmware downgrade fix it?

On some models, installing an earlier firmware version restores compatibility, then you must turn off auto-updates. HP has made rollback harder on newer printers, so it isn't always available.

Do remanufactured HP cartridges trigger the message?

Remanufactured cartridges that reuse the original HP chip are generally designed to be accepted, while those with replacement chips may be flagged. HP's own description says its printers accept cartridges with new or reused HP chips.

Can I use compatible cartridges in an HP+ printer?

No. HP+ requires Original HP supplies once activated. If your model ends in "e" and you haven't activated HP+, you may still have the choice at setup.

Does turning off firmware updates make my printer less secure?

Slightly, because security fixes also come through firmware. A reasonable middle ground is "notify me" so you can read the release notes and update on your terms.

Does HP Instant Ink work with compatible cartridges?

No. Instant Ink uses HP-supplied cartridges and requires automatic updates. Compare the costs in HP Instant Ink vs. compatible cartridges.

Is the message the same on OfficeJet and LaserJet?

The wording varies, but the cause is the same chip check. OfficeJet and ENVY inkjets more often show "Cartridge Problem" or "Incompatible cartridge," while LaserJets often say "Non-HP Chip Detected" or "Supply Problem."
