Purchasing Terms and Conditions:

1. Please judge whether your machine's problem is only the nozzle in advance before purchasing to avoid receiving the goods and installing them without solving the problem. It is recommended that customers consult our technical personnel in advance. Let our technical personnel analyze the fault and purchase the necessary parts.

2. When receiving the parcel, always open it in front of the courier to ensure that it is the item you ordered. If you find that the packaging is obviously compressed or deformed, carefully inspect the goods for any damage. If there is damage, you should refuse to accept it and call us to inform us of the situation: Of course, our packaging is very sturdy, so there should be no problem!

3. After receiving the goods, please do not install them while the machine is plugged in, to avoid damaging the motherboard.

4. After installation, please use the continuous ink supply or refill the ink cartridges to prevent the nozzle from clogging.

5. Final reminder: Please check the machine thoroughly before installation, other than the nozzle, to ensure there are no other issues. Avoid unnecessary losses.

After-sales products are non-refundable.
