1. This UV cartridge with float has a float switch inside, which automatically turns on when the ink is too low and turns off when the ink is full.

2. It is an affordable, environmentally friendly, energy-saving, high-quality output printer ink cartridge type. It achieves efficient and stable work when printing by designing the nozzle module and oil reservoir module separately and connecting them to each other through connecting pipes.

3. Economical and affordable: Compared with the integrated ink cartridge, the oil reservoir of the secondary ink cartridge can be replaced or added separately, thus reducing the cost of use.

4. Environmental protection and energy saving: Since the secondary ink cartridge can replace the oil reservoir separately, waste and pollution can be reduced. In addition, the electronic controller in the print head module can accurately control the amount of ink ejection, thereby reducing ink waste.

5. High-quality output: Since each nozzle hole can be individually controlled as needed, the secondary ink cartridge can achieve high-quality image and text output. At the same time, the flexible design of the connecting pipe also helps improve printing quality.
