How to Replace Printhead for HP OfficeJet Pro 8000 Series: 8022, 8025, 8035 and more

In this blog, we will walk you through the steps of replacing the printhead for the OfficeJet Pro 8000 series. Wotking on this HP printer requires a specific screwdriver bit. If you don’t have the right screwdriver, you can visit bchtechnologies.com to view and purchase our different screwdriver bits. We offer two Torx S2 Security Screwdriver bits that are similar, except that one has a handle and the other doesn’t. For this process, we will be using a T10 driver bit.

You’ll also need a pair of safety glasses or other eye protection to shield yoursel while working with the springs inside the printer.

Step 1

First, use your screwdriver to remove eight screws from the top of your printer. If you can’t find the eighth screw, lift the cover to reveal it. After that, we’re going to look at the scanner hinge. Use your screwdriver to push it forward towards the front of the printer, and the hinge should unlock pretty easily. At this point, the scanner can fall backward, and you can use another printer to stop it.

Step 2

On the back, you can see there are four screws in a row. You can lift the cover completely, but we don’t need to do that right now. By just slightly raising the cover, you will notice that there are two cables on the left side of the printer—we don’t want to disconnect these. Just leave the cables alone for now and work on the right side. Keep the left side in place, but lift the right side and stick a screwdriver underneath.

Step 3

Now you should see two big springs. We want to remove those, but remember to put your safety glasses on before proceeding, as they could hit you in the eye from the recoil as they are being removed. You can use a pair of long-nosed pliers to do this, but if you have a piece of steel wire handy, you can fashion it into a hook and use that instead to help pull the springs out. Use your finger to push them to the right side, and they should come out quickly this way.

Be sure to put these springs in a safe place. However, if you do happen to lose them, you can find replacement springs here.

Step 4

Lift the printhead and disconnect the cables. You don’t need any special tools to insert these wires into the new printhead. Just press evenly, and they should go in smoothly.

Step 5

We’ll now shift our attention to the long, clear cable that runs horizontally through the printer. This cable is a timing coding strip that should sit on your printhead’s sensor. The sensor has both a base and encoder. Your encoder belt is meant to connect to this coding piece.

Step 6

Once your printhead is tucked into the printer and connected to the coding cable, you can reinsert your springs. Connect the top hook of your first spring to the notch on your printhead to secure them together, making sure that they are locked in. Repeat this process with your second spring on the second hook. Pull the top of the spring all the way up and twist it onto the correct printhead notch.

Step 7

Reinsert the screws you took out at the beginning of this project and close the scanner. Now you’re good to go!
