Hi @Jorean,

Welcome to The HP Support Community.  

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

I understand you are facing an issue with your HP DeskJet 3722 isn't working after installing new ink, here are some troubleshooting steps to try:

May I know

1. Since when are you facing this issue

2. Have you made any changes on your printer post that this issue raised and have you observed any light blinking on the display and error code 

3. May I know if you are using genuine cartridges
4. May I know the operating system windows or Mac OS?
5. Could you please elaborate on the issue?
 

Check Cartridge Compatibility: Verify that the new ink cartridge is compatible with your DeskJet 3722. The correct cartridges for this model are typically HP 65 or HP 65XL (depending on your region).

Remove and Reseat the Cartridges: Sometimes, simply removing and reinserting the cartridges can solve connection issues. Make sure they're firmly clicked into place.

Check for Protective Tape: Ensure you remove any protective tape from the contacts and nozzles of the new cartridges, as this can prevent them from working.

Run a Printer Reset:

• Turn off the printer, unplug it from the power source, and wait for about 60 seconds.
• Plug the printer back in and power it on to see if it resolves the issue.

Clean the Cartridge Contacts: Dust or residue on the contacts can interfere with ink detection. Clean the contacts gently with a lint-free cloth.

Update or Reinstall Printer Software:

• Ensure that the HP Smart app or the HP printer software on your computer is up to date.
• If there is still no response, reinstall the software completely.

If the printer still won’t recognize the ink, the cartridge may be faulty. If possible, try a different cartridge to see if that works. Let me know if you still encounter issues!
