3mm 33.8cm by 24.7cm glass piece

Passo 1

Unplug the device from any energy sources.
Lift the top cover of the scanner.
Use a plastic opening tool to remove the plastic frame surrounding the glass.

Passo 2

Carefully pull the frame away from the glass.
If it doesn't remove easily, use the iFixit Opening Tool again to pry stuck sections.

I found it too difficult to unclip using a pry tool at the front edge. However as far as I can see, unless you need to replace the glass this surround can stay on place - there are no screws holding the shell together under the frame.

Passo 3

Use a T10 screwdriver to unscrew the two screws that fasten the frame to the printer hood.

Passo 4

Put your finger behind the panel with the power button.
Then, pull the piece outwards.

Note that: 1) there's a sprung clip behind, which you need to release - don't just pull!; and 2) the panel is held in by tabs on the left hand side, so it comes out with a rotation of the right side towards you.

Passo 5

Unscrew the screw inside the power button panel space.
Then, unscrew the screw that is across the printer slider.

Passo 6

Pull the white circuit board outwards which is located under the small screen.
Unplug the small ribbon cable from the circuit board.
Be careful when you unplug the ribbon cable not to use too much force. Using too much force may damage or rip the cable.

This is the small board with the on/off switch and an LED on it - it is brown, not white, in my own printer.

Passo 7

Unplug the small ribbon cable from the circuit board. Be careful when you unplug the ribbon cable not to use too much force. Using too much force may damage or rip the cable.

Passo 8

Pull the memory card reader's circuit board out.
Detach the white wiring connector from the back of the circuit board.
You may need to use a finger nail or a plastic opening tool to detach the white wiring connector from the circuit board.

Passo 9

Put your finger behind the small screen.
Then, pull it up.
Do not hesitate to use force to remove the TouchSmart panel.
Disconnect the ribbon cable from the small screen.

The screen, and the memory card reader module, do not have to come out to release the top cover, so depending on what you want access to you could leave them, and the small switch PCB, in place.
