„Replacing FINE Cartridges
When FINE Cartridges run out of ink, replace them using the following steps.
1Make sure that the machine is turned on, lift 
the Scanning Unit (Printer Cover) with both 
hands, then pull the Scanning Unit Support 
(A) down into place.
The FINE Cartridge Holder moves to the left.
Important
Handling FINE Cartridges
zDo 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
zTo maintain optimal printing quality, we recommend the use of specified Canon brand FINE 
Cartridges.
Refilling ink is not recommended.
zOnce you remove a FINE Cartridge, replace it immediately. Do not leave the machine with FINE 
Cartridges removed.
zReplace 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.
zOnce 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.
NotezIf 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.
zColor 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.

Keeping the Best Printing Results
To avoid drying of the Print Head and cl ogging of the nozzles, note the following.
„When You Turn Off the Machine
Follow the procedure below to turn off the machine.
(1) Press the  ON/OFF button to turn off the machine.
(2) Confirm that the  Power lamp has gone out.
This takes a few seconds or  as long as around 30 seconds.
(3) Unplug the power cord from the wall outlet.
If you are using a power outlet strip, you can switch it off instead.
When you press the  ON/OFF button to turn off the machine, the machine automatically puts a 
protective cap on the Print Head to prevent the ink from drying. If you remove the power cord or 
switch off the power outlet strip before the  Power lamp goes out, this capping will not be done 
properly, causing the Print Head to dry and clog.
„ When You Are Not Using the Machine for a Long Time
When you are not using the machine for a long time , print or copy in both black & white and in 
color, or perform Print Head Cleaning, about once a month to prevent degradation of the Print 
Head.
Numerous nozzles are installed in the Print  Head for high-precision printing. Just as the 
uncapped tip of a ballpoint pen or marker becomes  dry and unusable if it is not used for a long 
period of time, the print head nozzles become bl ocked by dried ink. Periodically printing or 
cleaning the Print Head can prevent this blockage.
Note
z Ink may blur depending on the paper in the following cases:
– Printed area is traced with a highlight pen or paint-stick, or
– Printed area is stained with water or sweat.
z If the print head nozzles get clogged, printouts will become faint or particular colors will not be printed 
properly. For details, see “When Printing Becomes Faint or Colors Are Incorrect” on page 57.
