INK EROR

[David_C89]

I am getting an error message that the ink cartridges are faulty or not installed properly.
I have opened, cleaned and replaced with a new ink cartridge and the error still appears.
What should I do?

Hi @David_C89,

Welcome to the HP Support Community.
 

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

If your HP OfficeJet Pro 7740 Wide Format All-in-One Printer is still showing the error message that the ink cartridges are faulty or not installed properly, despite cleaning and replacing them, try these troubleshooting steps:
 

1. Restart the Printer

• Turn off the printer.
• Unplug it from the power source.
• Wait about 2-3 minutes.
• Plug it back in and turn it on.
   

2. Check the Ink Cartridges Again

• Remove the cartridges and inspect for any protective tape (if new).
• Reinsert them carefully, ensuring they click into place.
• Use genuine HP ink cartridges—third-party or refilled ones may cause issues.
   

3. Clean the Ink Cartridge Contacts

• Turn off the printer and unplug it.
• Remove the ink cartridges.
• Use a lint-free cloth slightly dampened with distilled water to gently wipe the copper-colored contacts on the cartridges and the corresponding contacts in the printer.
• Let them dry completely before reinserting them.

I hope this helps.

Take care and have a good day.
