HP Smart Tank 515 Error: Cartridges not Communicating with Printer

[TaraGM]

I had an error that cartridges are not communicating correctly with the printer. I already plug and unplug multicolor and black cartridges separately. Because the blinking error persisted, I could not apply hard or half reset the printer. Could you help me fix this issue

Hi @TaraGM,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

Thanks for reaching out — we’re sorry to hear you’re experiencing trouble with your HP Smart Tank 515, and we appreciate you already trying the plug-and-unplug steps for the cartridges.

Let’s walk through a few more steps to try and resolve the “cartridges not communicating correctly” issue. This type of error often points to a connection issue between the printhead and the printer.

Step-by-Step Troubleshooting:

1. Make Sure the Printheads Are Installed Correctly

• Power on the printer
• Open the top cover to access the cartridges
• Ensure that both the black and tri-color printheads are securely seated
• Press down gently until they click into place

2. Clean the Electrical Contacts

Sometimes, ink or dust buildup can cause poor contact:

• Turn off the printer and unplug it
• Remove both cartridges
• Use a lint-free cloth lightly moistened with distilled water to clean:
  • The gold-colored contacts on the cartridges
  • The matching contacts inside the printer
• Allow everything to dry for a few minutes before reinstalling

3. Perform a Semi-Reset (if possible)

You mentioned not being able to apply a hard or half reset, but once the blinking error subsides or if the screen becomes responsive, try this:

• With the printer powered on, unplug the power cable from the wall
• Wait 60 seconds
• Plug the cable back in and power the printer on

Note: Some Smart Tank models use a button combination for resets. If the printer responds, we can guide you through a semi-reset sequence.

I hope this helps.

Take care and have a good day.
