Replacing Procedure
When the ink tanks run out of ink, follow the procedure below to replace them.
IMPORTANT
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 printer 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 printer will not be able to inform you when to replace the ink tanks properly.
Once an ink tank has been installed, do not remove it from the printer and leave it out in the open. This will cause the ink tank to dry out, and the printer may not operate properly when it is reinstalled. To maintain optimal printing quality, use an ink tank within six months of first use.
REFERENCE
Color ink may be consumed even when printing a black-and-white document or when black-and-white printing is specified.
