Hi @darren80,

Welcome to HP Support Community.

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

If your HP DeskJet 2734e printer is not recognizing brand-new black ink cartridges, the issue could stem from several factors. Here's a step-by-step troubleshooting guide.

Verify Cartridge Compatibility

• Ensure the black ink cartridge is compatible with your HP DeskJet 2734e. It typically uses HP 67 or HP 67XL cartridges.
• Check the packaging or the cartridge itself for the correct part number.

Inspect the Cartridge

• Protective Tape: Ensure the protective tape on the cartridge's electrical contacts has been fully removed.
• Contacts and Nozzles:
  • Inspect the electrical contacts (gold or copper-colored area) and nozzles for damage or dirt.
  • Gently clean these contacts with a lint-free cloth slightly dampened with distilled water.
• Allow it to dry for a few minutes before reinserting it.

Check Printer Contacts

• Open the printer’s ink cartridge access area and inspect the electrical contacts inside the printer.
• If you see any ink smudges or debris, carefully clean them with a soft, lint-free cloth and distilled water.

Perform a Hard Reset

• Turn off the printer and unplug it from the power source.
• Wait for 60 seconds.
• Reconnect the printer to power and turn it back on.
• Reinsert the black cartridge.

Update Printer Firmware

• Outdated firmware might cause the printer not to recognize newer cartridges.
• Update your printer's firmware via the HP Smart App or by visiting the HP Support website.

Run the Printer Troubleshooter

• Use the HP Smart App:
  • Open the app, navigate to your printer, and select "Printer Maintenance" or "Troubleshoot."
• On Windows:
  • Go to Settings > Devices > Printers & Scanners, select your printer, and choose Run Troubleshooter.

Try a Factory Reset

• If the issue persists, perform a factory reset:
  1. Turn off the printer.
  2. Hold down the Power button and Cancel button together for 10–20 seconds.
  3. Release the buttons when the printer restarts.

I hope this helps.

Take care and have a good day.
