HP Photosmart D110a Motherboard Replacement

First, begin by removing the printer's hood.

Open the printer's mouth by simply pulling down on it; there are 2 mouth pieces that need to be pulled down.

Adjust the flap covering the scanner upward, as shown.

Remove the flap for the scanner. The flap is attached with two clips that can be dislodged by pulling lightly away from the printer.

Locate the three screws on top of the printer.

The orange circle shows a fourth screw located behind the power panel. Directions to remove this screw are in a later step.

Remove the three screws from the top of the printer with a T-9 screwdriver as shown.

To access and remove the fourth and final screw attaching the hood, the panel for the power button must be removed as follows:

Reach into the mouth of the printer and press on the small clip behind the power button. This allows the panel of the power button to be removed.

After pressing the clip, pull out the power button panel by pulling from right to left.

Remove the exposed screw that was covered by the power button panel.

This step is easier with two people. Carefully have one person lift the hood of the printer 2-3 inches above where it was resting.

Remove the ribbon cables and wires attaching the motherboard (the only green PCB board) to the hood by gently pulling upward on them.

When all three cables are removed, lift the hood away from the printer and set it aside.

Once the lid is removed, the motherboard (the only green PCB board) will become accessible.

Use a T9 Torx Security screwdriver to remove the three screws securing the motherboard.

With your fingers or a spudger, remove the cables and ribbon cable by gently pulling them free from their sockets.

Gently lift the mother board up from the printer and set it aside.
