IMPORTANT : BCI-24 Color compatible cartridge has a sponge , It is important to refill your ink cartridge either before it runs out of ink or as soon as possible after it begins to streak or the printer gives you a LOW ink alarm. Inks are designed to dry quickly to prevent bleeding or smearing on your printouts, Since this ink dries so quickly if you run out of ink and do not refill as soon as possible the ink in the print head will dry and clog the print head holes which are smaller than the diameter of a human hair and there may be as many as 100 holes on each print head any of which can become clogged up causing poor print quality.
