Replacing Procedure
When the ink tanks run out of ink, follow the procedure below to replace them.
Important
Handling ink
To maintain optimal print quality, we recommend the use of specified Canon brand ink tanks. Refilling
the 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.
Once an ink tank has been installed, do not remove it from the machine and leave it out in the open.
This will cause the ink tank to dry out, and the machine may not operate properly when it is
reinstalled. To maintain optimal printing quality, use an ink tank within six months of first use.
Note
Color ink may be consumed even when printing a black-and-white document or when black-and-
white printing is specified.
Every ink is also consumed in the standard cleaning and deep cleaning of the Print Head, which
may be necessary to maintain the machine's performance. When an ink tank is out of ink, replace it
immediately with a new one.
