• Accessing the Mainboard

Remove the printer's outer cover by carefully unscrewing the screws that secure it in place. Place the screws in a safe location to avoid misplacing them. Once the cover is removed, you will have clear access to the mainboard.

Carefully disconnect all cables and connectors attached to the mainboard. It is essential to exercise caution during this step to avoid damaging any delicate components. Make sure to take note of the cable locations or capture clear images for reference when reconnecting them later.

• Removing the Mainboard

Once all cables are detached, unscrew the screws that secure the mainboard to the printer chassis. Gently lift the mainboard out of its position, ensuring not to apply excessive force or bend any components. Place the mainboard in an anti-static bag or on an anti-static mat to prevent any potential damage.
