Hi @reshmakham,

Welcome to HP Support Community.

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

The "Supply System Problem" message on your HP OfficeJet Pro 9720e Wide Format All-in-One Printer typically indicates an issue with the ink supply system. Here are steps you can follow to resolve the issue.

Restart the Printer

• Turn off the printer and unplug it from the power source.
• Wait for 2–3 minutes.
• Plug the printer back in and turn it on to see if the error clears.

Check Ink Cartridges

• Open the printer's cartridge access door and inspect the ink cartridges.
• Ensure all cartridges are:
  • Properly seated in their respective slots.
  • Installed correctly and securely.
  • Free from damage or ink leaks.
• If a cartridge appears damaged, replace it with a new, genuine HP cartridge.

Clean the Ink Cartridge Contacts

• Turn off the printer.
• Remove the cartridges and gently clean the gold-colored contacts on both the cartridges and the cartridge holder with a lint-free cloth slightly dampened with distilled water.
• Let them dry for a minute, then reinstall the cartridges.

Reset the Printer

• Perform a factory reset:
  • Go to the Settings menu on the printer touchscreen.
  • Navigate to Printer Maintenance or Printer Setup, and select Restore Defaults.
  • Confirm to reset the printer to factory defaults.

Update Firmware

• Ensure your printer is running the latest firmware:
  • Visit HP's support page and download the latest firmware for your model.
  • Install the firmware using your computer.

Check the Ink Supply System

• Inspect the ink supply tubes (if visible) for clogs, air bubbles, or disconnections.
• Perform a printer diagnostic test from the printer menu to check for ink flow issues.

Run an Ink System Reset

• Remove all ink cartridges and close the cartridge access door.
• Turn off the printer and unplug it.
• Wait for 5 minutes, then reconnect the printer and power it on.
• Reinsert the cartridges when prompted.

I hope this helps.

Take care and have a good day.
