The common ink head structures of ink-jet printers mainly include ink-jet head and ink cartridge integrated machine and separate type. When the ink cartridge is used up, the ink head and ink cartridge of integrated machine ink head structure should be replaced together. Such structures are relatively tight and reliable, but the cost is relatively high; The ink head and ink cartridge of the separated structure are separated, and the ink cartridge can be replaced separately after the ink is used up, which can save costs to a certain extent.
At present, most commonly used printers on the market (such as EPSON, CANNON, etc.) use a dual ink head structure: a black (or Photo) ink head and a color ink head. In the ink cartridges, most of the black ink cartridges are independent, while the other three color ink cartridges are integrated. There are also some products with ink cartridges of each color that are independent and can be replaced separately, further reducing the printing cost.
