1.Remove the fixing screws on both sides of the nozzle cover (in the case that it is not glued. If it is, skip directly to the next step). If it's a K1 MAX machine, you also need to remove the profilometer and the bracket.
2.Use a hot air gun or hair dryer to heat the glue that covers the screws and prevents the fan cover from being removed. If there is only a small amount, you can use the wire cutters provided with the machine to assist in the operation. If there is a lot, it is recommended to use needle-nose pliers or vise-grip pliers. (Be careful of burns from the hot air).
3.After the removal of the nozzle cover. Remove the fixing screws and ribbon cable of the nozzle plate, the terminal at the back also needs to be dismantled.
4.After removing the nozzle plate, proceed to unscrew the six screws that secure the heat sink (two at the front, one on each side, and two on the nozzle assembly at the bottom). The screws at the bottom nozzle are usually wrapped in adhesive. Without clearing it, the screws cannot be unscrewed, preventing the entire heat block from being dismantled. Therefore, a heat gun is needed to slowly clean off the adhesive on the bottom screws before unscrewing them. Once the heat block module is removed, the issue of adhesive leakage can be resolved.
5.Finally, replace the corresponding damaged parts according to the actual situation and reinstall them.
