Introduction

The motherboard is the brain of the printer, so if anything goes wrong with it, your entire printer becomes worthless. In order to access it, you will need to remove the side panel.

To remove the motherboard, you will need to remove several connectors, so a set of small hands will be helpful. You will also need a screwdriver to remove the four 8mm T9-Torx screws securing it in place.

Be sure to ground yourself and the device when removing the motherboard and its connectors so short circuits do not occur.

Be sure to set a space aside for the screws so you don't lose them.

    • Turn off the printer and remove the power cable.

    • Remove two 13mm T9 screws using a T9-Torx screwdriver. Turn counterclockwise until the screws are released.

    Apparently screws are T10 not T9. T9 driver/bit works, but you'll slightly damage the screw. I use a T10 now.

    • Release any remaining connectors from the motherboard by gently pulling away until they break free.

    • Remove the motherboard.

    • Mark each connector or remember their placement for reinstallation to avoid damage to components. If the connector does not snap in easily, don't force it.

Conclusion
