• Replacing Ink Tanks
When ink tanks run out of ink, replace them using the following steps.
~ Important
Handling Ink
• To maintain optimal printing quality, we recommend the use of specified Canon brand ink tanks.
Refilling ink is not recommended.
• Once you remove an ink tank, replace it immediately. Do not leave the machine with ink tanks
removed.
• Replace empty tanks with new ones. Inserting partially used ink tanks may cause the nozzles to
clog. Furthermore, with such tanks, the machine will not be able to inform you when to replace
the 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.
• Color ink may be consumed even when printing a black-and-white document or when black-
and-white printing is specified.
Color ink is also consumed in Print Head Cleaning and Print Head Deep Cleaning, 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.
