How to Change Printer Cartridge Sponges

Updated February 21, 2017

If you are looking to save money and refill your own print cartridges, eventually the print cartridge sponge will also need to be replaced. Worn out or partially clogged print cartridge sponges can cause splotchy or faded print quality when the print cartridge is full of ink. Changing the print cartridge sponge is about as difficult as refilling the ink cartridge.

Remove the print cartridge from the printer. Open the printer's lid to carefully lift the cartridge out of the cartridge carriage.

Drill two holes in the cartridge, if it has not be refilled previously. Perform this step over a sink. One hole will be on the top of the cartridge and the other on the bottom.

Insert the liquid syringe into each hole in the print cartridge and extract any leftover ink. Store the ink in a clean, small plastic container.

Remove the top of the print cartridge. Different model cartridges may differ, but most can be removed by wedging a flathead screwdriver in the crease between the top of the cartridge and its sides. Do no be afraid to apply force; the cartridge's top will not come off easily.

Remove the print cartridge sponge. Replace it with the new sponge, making sure you put it in the way the old sponge was sitting.


Printer ink will dye fabrics or any skin it comes in contact with, so be careful not to spill it.
