Certain Canon printer models have a microchip that tells the printer how much ink is left in the cartridge as well as if the cartridge came directly from Canon. If you are using a refilled or aftermarket cartridge in a Canon printer, the ink monitoring software will block the use of the cartridge. There is, however, a way to get around the monitoring software.

Skill level:


  1. 1

    Turn on your Canon printer and wait for the warm-up process to complete. Open the printer's access door and wait for the cartridge carriage to come to a complete stop.

  2. 2

    Remove the cartridge to be replaced and insert the refilled or aftermarket cartridge. Close the printer's access door.

  3. 3

    Wait for the printer to detect the new cartridge. An error message will come up on the screen to say the printer cannot detect the ink level on the new cartridge.

  4. 4

    Click on "Yes" to indicate that you want to use the new cartridge despite the risk of damage to the printer if the cartridge leaks.

  5. 5

    Click on "Yes" one more time to acknowledge that you understand Canon will not be responsible for damage done to the printer by the new cartridge.

  6. 6

    Press and hold the "Resume" button on the printer for at least five seconds. The "Resume" button will be flashing. If your printer does not have the "Resume" button, press and hold the "Ok" or "Cancel" button.

  7. 7

    Use the printer as normal, keeping in mind the ink monitoring software will not show the ink level for the new cartridge.

Tips and warnings

  • Never force an ink cartridge into or out of the printer. An ink cartridge should easily click into and out of its spot in the printer.
