Hi @Faris34,

Welcome to The HP Support Community.  

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

I understand the error message "There is a problem with the supply system" on your HP OfficeJet Pro 7720 usually indicates an issue with the ink cartridges or the printhead. Here's how you can troubleshoot this problem:
 

1. Check the Cartridges:

• Ensure Genuine HP Cartridges: Make sure you are using genuine HP ink cartridges. Non-HP or refilled cartridges can sometimes cause errors.
• Reinsert the Cartridges: Remove each cartridge and then reinsert them, making sure they are properly seated in their slots.
• Check for Damage: Inspect the cartridges for any visible damage, such as leaks, cracks, or missing contacts.

2. Inspect the Printhead:

• Remove and Clean the Printhead: If the error persists, carefully remove the printhead and clean the electrical contacts with a lint-free cloth and distilled water. Allow it to dry completely before reinserting it.
• Reinstall the Printhead: After cleaning, reinstall the printhead securely.

3. Check for Firmware Updates:  Update the firmware on an HP printer

• Update Firmware: Make sure your printer's firmware is up to date. You can check for updates through the HP Smart app or by visiting the HP support website.

4. Reset the Printer:

• Perform a Power 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.

5. Factory Reset (Last Resort):

• Since you've already performed a factory reset, you may need to try it again after ensuring that all cartridges are properly installed and there are no issues with the printhead.
