Hi @wjfj150,

Welcome to The HP Support Community.  

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

Replacing the cartridge holder (also known as the printhead or carriage) on an HP OfficeJet Pro 8720 can sometimes fix supply system problems, but it depends on the specific nature of the issue. 

Here are some steps and considerations to determine if this is a viable solution:

Diagnosing the Supply System Problem

Error Message: Identify the exact error message on the printer screen. Common supply system errors include "Supply System Problem," "Cartridge Problem," or specific errors related to individual cartridges.

Troubleshooting Steps:

• Restart the Printer: Turn off the printer, unplug it, wait for a minute, then plug it back in and turn it on.
• Check Cartridges: Remove and reinsert the cartridges. Ensure they are installed correctly and securely.
• Clean Contacts: Use a lint-free cloth and distilled water to gently clean the electrical contacts on the cartridges and the printhead.
• Update Firmware: Ensure the printer firmware is up to date by checking the HP support website.

Considering Cartridge Holder Replacement

Persistent Issues: If the problem persists after basic troubleshooting, the cartridge holder might be faulty. This can happen due to wear and tear or damage to the electrical contacts.

Replacing the Cartridge Holder:

• Compatibility: Ensure you get the correct part for the HP OfficeJet Pro 8720. The part number and compatibility information can usually be found in the printer's service manual or by contacting HP support.
• Installation: Replacing the cartridge holder can be complex and may void your warranty if not done correctly. It often involves opening the printer casing and handling delicate components.

Steps to Replace the Cartridge Holder

Preparation: Turn off the printer and unplug it. Gather the necessary tools, such as screwdrivers and pliers, and ensure you have a clean, static-free workspace.

Accessing the Cartridge Holder:

• Open the printer cover to access the cartridge area.
• Carefully remove the cartridges and set them aside.
• Locate the screws or clips holding the cartridge holder in place and remove them.

Removing the Old Cartridge Holder:

• Disconnect any cables or ribbons attached to the cartridge holder.
• Carefully remove the old cartridge holder from the printer.

Installing the New Cartridge Holder:

• Position the new cartridge holder in place and reconnect any cables or ribbons.
• Secure the holder with screws or clips.
• Reinstall the cartridges and close the printer cover.

Testing:

• Plug in the printer and turn it on.
• Run a test print to ensure the new cartridge holder is functioning correctly.
