A unique feature for the Canon I series printers and fax machines is the built-in waste ink tank. The tank captures the waste ink, preventing spillage outside of the machine itself. When the tank becomes full (or when the machine believes it to be full) you will be prompted to have the waste ink tank cleaned. You can return the product to have it cleaned by a Canon technician, or you can do it yourself.

  1. 1

    Remove the outer plastic shell by lifting the release flaps to the rear of the printer. The two tabs are located at either ends and will be released with moderate pressure.

  2. 2

    Remove the ink cartridge housing by unscrewing the unit from the machine. There is no need to remove the individual cartridges.

  3. 3

    Remove the spongelike pads held beneath the cartridge housing unit while wearing gloves.

  4. 4

    Rinse the pads with water or a combination of water and rubbing alcohol.

  5. 5

    Fold the pads in half to squeeze out the remaining water or alcohol. Do not twist them.

  6. 6

    Replace the pads and reattach the ink cartridge unit. Close the machine (it snaps into place).

  7. 7

    Reset the machine to avoid a reoccurring warning.
