The sponge is usually located at the bottom of the inkjet printer cartridge and absorbs ink. When the printer needs to eject ink, the nozzle draws the ink from the small sponge to print the pattern onto the paper. Therefore, the quality of the sponge directly affects the printing effect. The printer cartridge is one of the basic accessories of the printer, and there is usually a small sponge embedded in the cartridge. This sponge is the printer cartridge sponge. If there is no sponge in the ink cartridge, the ink poured in will thicken quickly or even dry out, making it inconvenient to use and difficult to clean. But the ink in the sponge can be kept for a very long time, so it plays the role of ink storage.
