@Tamaira1234, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding your ! 

We're thrilled to have the opportunity to assist you and provide a solution.  

If your HP OfficeJet Pro 8710 All-in-One Printer indicates that the printhead is missing, not detected, or incorrectly installed, you can follow a step-by-step procedure to resolve the issue:

Step 1: Remove and Reinstall the Printhead

1. Turn on the printer.
2. Open the ink cartridge access door.
3. Wait until the carriage is idle and silent before you continue.
4. Lift the carriage latch handle to unlock the printhead.

Without removing the ink cartridges, grasp the sides of the printhead, and then lift the printhead and pull it toward you.

Note: To avoid ink stains, do not touch the bottom of the printhead.

1. Place the printhead face-up on a sheet of paper, and then set aside.

Step 2: Insert the New Printhead

Remove the new printhead from the package, insert it into the printer, and then lower the carriage latch handle.

Caution: Do not touch the electrical contacts or the nozzles. Touching these areas can cause electrical failures or print quality problems.

1. Grasp the printhead on both sides with the electrical contacts facing the rear of the printer, and then insert the printhead into the carriage.

1. Carefully lower the carriage latch handle until it snaps into place.

Step 3: Insert the SETUP Ink Cartridges

1. Make sure plain white paper is loaded into the input tray.
2. Remove the SETUP ink cartridge from its package.
3. Carefully insert the SETUP ink cartridge into its slot, and then push the ink cartridge forward until it snaps into place.

1. Repeat these steps for the other SETUP ink cartridges.
2. Ensure each ink cartridge is not sticking out farther than the other ink cartridges. If an ink cartridge is sticking out, push it until it snaps into place.
3. Close the ink cartridge access door.

The printer will then start an initialization process. It is normal for the printer to make noises during this process. After the process completes, the printer prints an alignment page.  

Take care, and have an amazing day!
