How to Remove the Motherboard on an ET-8550 Printer

If you own an ET-8550 printer and encounter the 031006 error, don't worry, it is pretty easy to fix. In this article, we will guide you on how to remove the motherboard from your ET-8550 printer, step by step.

Before we begin, make sure you have a few tools ready, including a screwdriver, pliers, and a camera or smartphone to take photos. Also, it's a good idea to purchase a connection diagram or visit BCH Technologies' website to ensure you know which cable goes where when you put it back together.

First, remove the live panel by unscrewing the four screws, including one in the front, one in the back, and two on the sides. Then, gently push the panel in the direction where the panel stops you, and jiggle it a bit until you can slide it out.

Next, remove the right side cover by unscrewing three screws, including one on the front, one in the back, and one under the ink tank cover. After that, push the panel in the opposite direction and lift it up straight, then remove the panel.

Now, you need to remove the cables from the motherboard. It's essential to take photos of each step before you remove any cables. Next, remove two FFC cables and unplug the plug from the front panel.

To remove the front panel, unscrew the screw underneath the tank and push the tab in, then remove the screw on the right side of the tank. Underneath the tank cover, pry it open, and then you can remove the whole front panel as one piece.

Finally, you can remove the motherboard by unscrewing the two machine screws at the bottom of the printer, pulling off all the cables, and unscrewing the ground wire.

Therefore, removing the motherboard from an ET-8550 printer is not that complicated, but it requires some patience and attention to detail. We hope this article helps you solve your printer problem.
