Your HP printer can reject ink even when the cartridge looks new, full, and seated. The usual causes are a loose cartridge, protective tape, dirty contacts, the wrong cartridge number, HP+ or Instant Ink rules, or a printhead that needs cleaning. Start with the quickest hardware checks, then move to the account, firmware, and policy fixes that match the message on the printer.
Reset and reseat the cartridge first
Start here because this clears the fastest cartridge-detection failures without changing printer settings.
- 1.Press the printer Power button to turn it off.
- 2.Unplug the power cord from the printer and the power source, wait 60 seconds, then reconnect it directly to a wall outlet and the printer.
- 3.Press Power to turn the printer on, open the cartridge access door or lid, and wait until the carriage is idle and silent.
- 4.Remove the indicated cartridge, check the correct slot, remove any protective tape from the contacts or nozzles, then reinstall the cartridge firmly.
- 5.Close the access door and try printing again after the printer finishes its startup checks.
Match the cartridge to your exact printer
A cartridge can click into place and still be wrong for the printer. Use HP's compatible-cartridge lookup for your exact model, then compare the cartridge number and the region or market on the packaging or label.
For HP+ printers, install Original HP cartridges. For HP printers with dynamic security, use cartridges with new or reused HP chips or HP electronic circuitry; firmware can block non-HP chips or modified non-HP circuitry.
If the cartridge matches the model and is still not recognized, clean the cartridge and carriage contacts next. A clean, properly seated compatible cartridge gives the printer the right baseline before you replace hardware.
Check new ink and SETUP cartridge errors
Use this when a new cartridge fails right after installation, the printer says a cartridge is missing, or a new printer asks for SETUP cartridges. New-cartridge errors usually come from packaging tape, the wrong startup cartridge, or a cartridge that was not seated firmly.
Turn the printer on, open the access door, and wait until the carriage stops moving. Remove the cartridge named in the printer message.
Peel off protective tape from the contacts or nozzles without touching the copper contacts or ink nozzles. Put the cartridge back into the correct slot and press it in until it is seated.
On a new printer that shows Use SETUP Cartridges, install the SETUP cartridges that came with the printer. If those cartridges are not available, follow the HP support prompts for the printer before trying ordinary replacement cartridges again.
Clean dirty electrical contacts
The most common cause of a missing, incompatible, failed, or not-recognized cartridge message after handling the cartridge is poor electrical contact between the cartridge and the carriage.
Remove the cartridge and lightly dampen a lint-free cloth or swab with distilled water. Wipe the copper-colored contacts on the cartridge, and do not touch the ink nozzles with your fingers.
Clean the electrical contacts inside the carriage the same way, then let the contacts dry. Reinstall the cartridge, close the access door, and print a test page.
If the printer only shows Ink Alert or Low on Ink and print quality still looks acceptable, select OK to close the message and keep printing. Replace the cartridge when the output becomes unacceptable or the cartridge is empty.
If the message says the cartridge is used, refilled, or counterfeit and the printer is not enrolled in Instant Ink, choose No, OK, or Continue when the printer, computer, or HP app offers it. When printing does not continue, replace the cartridge with a compatible supply.
Clean the printhead when ink is recognized
Use cleaning tools when the cartridge is accepted but black ink, color ink, or normal print quality is still missing.
- 1.Load plain paper before starting any cleaning or alignment tool.
- 2.On the printer control panel, open Setup, Settings, Tools, or Printer Maintenance, then choose Clean Printhead, Clean, or Clean Cartridges.
- 3.On Windows models with HP Printer Assistant, open Maintain Your Printer, then Device Services, then Clean Ink Cartridges.
- 4.In the HP app, select your printer, open Printer Settings or Advanced Settings, then choose Print Quality Tools and Clean Printhead or Clean.
- 5.Print and evaluate the test page, then run Align Ink Cartridges or Align Printhead if the printer asks for alignment after cleaning or cartridge replacement.
Update the HP app and printer firmware
This fixes cartridge problems caused by outdated printer tools, missing diagnostics, or firmware recognition issues.
Install the current HP app from HP's official app page or 123.hp.com. Choose Apple App Store, Mac App Store, Google Play Store, or Microsoft Store, or enter your printer model at 123.hp.com and follow the prompts.
Use the current HP app, not older HP Smart download instructions. HP says HP Smart is no longer available for download. If you download a firmware file yourself, take it only from HP's support page for your exact printer model; HP also delivers firmware updates through the printer control panel, the HP app, and the Embedded Web Server.
Open HP's printer drivers and software download page, enter or select your printer model, choose your operating system when prompted, and download the available driver, software, diagnostics, or firmware package.
For a firmware update from the printer itself, connect by Wi-Fi or Ethernet. Open Setup, Service, or Settings, then use Preferences, Printer Maintenance, or Tools, choose Web Services, Printer Update, or LaserJet Update, then select Check for Updates and install the update without turning the printer off.
From the HP app, select the printer and open Printer Settings or Advanced Settings, which opens the printer's Embedded Web Server. HP documents two update layouts, so use the one your printer shows. On printers with the older layout, open About printer, then Firmware update, then Check now. On printers with the current Advanced Settings layout, select the Printer Update tile, or Tools, then Printer Updates, then Firmware Updates, and select Check for Update.
For a firmware update from a computer, keep the printer on and connected, run HP Printer Update, select the checkbox next to the serial number when the status is Ready, then click Update. When the status is Up-to-Date, no firmware update is needed.
Fix Instant Ink and HP+ cartridge blocks
This applies when your printer is enrolled in Instant Ink, has HP+ enabled, or rejects a subscription cartridge. These services can make a cartridge problem look like bad ink when the real issue is account status, printer connectivity, or supply rules.
For Instant Ink cartridge errors, install your reserve cartridge first. If you do not have a reserve cartridge, contact HP Instant Ink support for a replacement.
When cartridges did not arrive or subscription cartridges are disabled, sign in to your HP account or Instant Ink dashboard. Confirm that the account and printer are active, check shipments in transit, make sure the printer is connected to the internet, and update the mailing address if it is wrong.
If you cancel Instant Ink, subscription cartridges are remotely disabled after cancellation. At the end of the billing cycle, remove the Instant Ink cartridges and install regular cartridges so printing can continue.
HP+ printers require Original HP cartridges. On non-HP+ printers after Instant Ink cancellation, HP's terms allow HP original or compatible third-party cartridges, but dynamic-security printers can still block cartridges that do not have HP chips or HP electronic circuitry.
Turn off cartridge policy settings where available
Some HP ink, OfficeJet, toner, LaserJet, and PageWide models expose settings for Cartridge Protection or Authorized HP Cartridge Policy. These settings apply only where the printer offers them, and they do not override HP+ or dynamic-security supply requirements.
Cartridge Protection turned off affects future cartridges only. It does not unlock a cartridge already protected by another printer, and HP+ restrictions cannot be disabled for the life of the printer.
On a printer you own, open Menu or Setup, then Settings or System Setup, then Supplies or Supply Settings, and set Cartridge Protection to Off. For Authorized HP Cartridge Policy messages, use the same supplies area and set Authorized HP Cartridge Policy or Cartridge Policy to Off.
You can also open the printer's Embedded Web Server from its IP address, enter the printer PIN from the sticker inside the cartridge door or rear label when prompted, then use Settings, Supplies, Supply Settings, Cartridge Protection, or Cartridge Policy, and click Apply.
If a work, school, or managed-office printer still blocks the supply, ask the owner or IT admin to change the setting or provide the approved cartridge. If the printer is yours and the block remains, replace the cartridge with a compatible supply that meets the printer's HP+ or dynamic-security requirements.
Use HP support before a factory restore
When the same cartridge error survives reset, reseating, contact cleaning, compatibility checks, cleaning tools, firmware updates, and account fixes, use HP's cartridge-error support page or support inside the HP app. HP's Virtual Assistant covers Ink Cartridge Problem, Ink Cartridge Failure, Incompatible Ink Cartridges, Incorrect Ink Cartridge, Low on Ink, and related errors.
Some in-warranty cartridges may qualify for replacement. Use the HP support path for the printer before replacing more supplies.
Restore factory defaults only after narrower fixes fail or HP support directs it. On touchscreen printers, open the Dashboard if needed, go to Tools or Printer Maintenance, choose Restore, then Restore Factory Defaults, and confirm.
After the restore, reconnect and set up the printer again, then reinstall the cartridges when prompted. If the same cartridge fails after setup, replace it with a compatible cartridge.
Frequently Asked Questions
Why does my HP printer say the cartridge is incompatible or not intended for use?
The cartridge may not match the exact printer model, cartridge number, or region. HP+ printers require Original HP cartridges, and dynamic-security printers can block cartridges without HP chips or HP electronic circuitry.
Can I keep printing after a Low on Ink message?
Yes, when print quality is still acceptable. Select OK to close the alert, monitor output, and replace the cartridge when print quality becomes unacceptable or the cartridge is empty.
Do I still need SETUP cartridges for a new HP printer?
Yes, when the printer asks for them during first-time setup. Install the SETUP cartridges that came with the printer before using ordinary replacement cartridges.
Does turning off Cartridge Protection unlock a cartridge from another HP printer?
No. Turning Cartridge Protection off affects future cartridges only. It does not unlock a cartridge already protected by another printer, and HP+ supply restrictions cannot be disabled.
