Handling ink
To maintain optimal print quality, we recommend the use of specified Canon brand ink tanks. Refilling ink is not recommended.
If you remove an ink tank, replace it immediately. Do not leave the machine with ink tanks removed.
Use new ink tanks for replacement. Installing used ink tanks may cause the nozzles to clog. Furthermore, with such ink tanks, the machine will not be able to inform you when to replace the ink tanks properly.
To maintain optimal print quality, use ink tanks within 6 months of first use. (We recommend you to put down the date when installing them.)
