1.The Innovation of nozzle design:
Gem nozzle with injection molding process makes nozzle stronger and more resistant to falling.
Other inkjet printers:
99.9% of the printers use traditional nozzles for general stability. But they can not be anti-drop and the nozzle is very delicate and can not touch, let alone fall to the ground (Common problem is caused by the displacement of the spray chamber, the ink line will be biased, etc.).
