How to Reset Ink Levels on Canon Mx300
Rest the ink level on your Canon MX300 to get rid of error messages. (ink cartridges image by itsallgood from

The Canon Mx300 is an all-in-one printer/scanner/fax machine/copier. It's primarily designed for office or home office use. It prints in both black and white and colour, and like all printers, it requires ink refills from time to time. If, however, you've refilled your Canon Mx300 printer ink already and you're still getting a "low ink" error, you'll need to reset the ink level. This will prevent pop-up messages from appearing, as well as preventing any ink-related printing problems from occurring.

Skill level:


  1. 1

    Turn off your printer and unplug its power source from the wall.

  2. 2

    Press and hold down the "Power" button, while simultaneously plugging the power source back into the wall.

  3. 3

    Press and hold the "Cancel/Stop" button (while still holding down the power button) three times. Release the power button and wait for several seconds, until the printer screen says "Idle."

  4. 4

    Press the "right arrow" key on the printer until the screen reads "Shipping Mode 3." Press the "OK" button twice. At this point, a test page should print.

  5. 5

    Open the top cover of the printer, as if you were going to change the ink cartridges.

  6. 6

    Unplug the power source to the printer, without first turning it off with the "Power" button.

  7. 7

    Remove the ink cartridges and close the cover.

  8. 8

    Plug the MX300's power source back into the wall and press the "Power" button to turn it back on. Replace the cartridges and the printer should acknowledge that the ink is full.
