Learn how to replace the ink cartridge in your PIXMA MG2420 or MG2520.


Before you begin

There are a few things to know about replacing the ink cartridge.

  • If you remove the cartridge, replace it immediately. If either the black or color cartridge isn't installed, an error occurs and the machine can't print.

  • Use a new ink cartridge. A used ink cartridge may cause the nozzles to clog and it won't tell you when it's time for a replacement.

  • Don't leave a new ink cartridge out in the open after the packaging is removed. This causes the cartridge to dry out, and the machine may not operate properly once the cartridge is installed.

  • The inside of the machine may be stained with ink. Be careful not to stain your hands or clothing when replacing the cartridge. You can use a clean white cloth to gently wipe off any ink inside the machine.

  • ​To maintain optimal print quality, use the cartridge within six months of first use.
