Replacing FINE Cartridges
When FINE Cartridges run out of ink, replace them using the following steps.
Important
Handling FINE Cartridges
Do not touch the electrical contacts or Print Head Nozzles on a FINE Cartridge. The machine
may not print out properly if you touch it.
(A) Electrical Contacts
(B) Print Head Nozzles
To maintain optimal printing quality, we recommend the use of specified Canon brand FINE
Cartridges.
Refilling ink is not recommended.
Once you remove a FINE Cartridge, replace it immediately. Do not leave the machine with FINE
Cartridges removed.
Replace empty cartridges with new ones. If you insert FINE Cartridges that has been removed
once, the machine may not print out properly due to some reasons such as clogging of the
nozzles.
Furthermore, with such cartridges, the Low Ink Warning may not be displayed properly.
Once a FINE Cartridge has been installed, do not remove it from the machine and leave it out in
the open. This will cause the FINE Cartridge to dry out, and the machine may not operate
properly when it is reinstalled. To maintain optimal printing quality, use a FINE Cartridge within
six months of first use.
Note
If a FINE Cartridge runs out of ink, you can print with either Color or Black FINE Cartridge, in
whichever ink remains, only for a while. However the print quality may be reduced compared to
when printing with both cartridges. Canon recommends to use new FINE cartridges in order to
obtain optimum qualities.
Even when printing with one ink only, print with leaving the empty FINE Cartridge installed. If
either of the Color FINE Cartridge or Black FINE Cartridge is not installed, an error occurs and
the machine cannot print.
For information on how to configure this setting, refer to the PC Printing Guide on-screen
manual.
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.
