Hi @haycock,

Welcome to HP Support Community.

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

If your HP 7740 printer is detecting the new 952 XL toner cartridges as empty, here are some steps you can take to troubleshoot the issue:

1. Check Cartridge Installation

• Ensure that the cartridges are installed correctly. Remove each cartridge and reinsert them to ensure they are seated properly.

2. Inspect for Protective Seals

• Make sure any protective tape or seals on the new cartridges have been removed. Sometimes cartridges have plastic seals that prevent them from functioning if not removed.

3. Perform a Printer Reset

• Turn off the printer and unplug it from the power source.
• Wait for about 60 seconds, then plug it back in and turn it on. This can sometimes reset the ink level reporting.

4. Clean the Contacts

• Inspect the metal contacts on the cartridges and inside the printer. Wipe them gently with a lint-free cloth to remove any dust or residue.

5. Check for Firmware Updates

• Make sure your printer’s firmware is up to date. You can check for updates through the HP Smart app or the HP support website.

6. Run a Print Head Cleaning

• Access the maintenance menu on the printer and run a print head cleaning cycle. This can sometimes resolve issues with ink detection.

7. Check Cartridge Compatibility

• Ensure that the cartridges are genuine HP cartridges and compatible with your HP 7740 model. Third-party or refilled cartridges can sometimes cause issues.

8. Print Test Page

• Attempt to print a test page to see if the printer recognizes the ink levels correctly during the print job.

I hope this helps.

Take care and have a good day.
