Why is there a sponge in my ink cartridge? -

Why do some inkjet printers have ink cartridges with sponges in them, while others just have a chamber for the ink? What purpose do the sponges serve?

The sponges in the ink cartridges are to deliver ink by capillary action. They actually were a more refined way of delivering the ink. The older inkl cartridges have a bladder and if there was a problem with the nozzle they tended to leak in the printer. The sponge type does awaay with this risk.

This is so the sponge holds most of the ink, and so you run out of ink faster and have to go out and buy a new cartridge all the time. These companies just think of everything to make more money, and rob the poor consumers! Don t get a sponge ink holding printer. Get a free flowing fluid ink jet printer cartridge only.

that is so it can absurb the ink

To keep the ink from sloshing around; to quot;wickquot; every last drop of ink; to lessen leakage; and to regulate the ink flow . . . I think (?)

for a consistent ink flow
