zWhen Replacing the Clear Ink Tank
When the clear ink tank (PGI-9Clear) runs out of ink, replace it using the following steps.
1Open the Scanning Unit (Printer Cover) and the Paper Output Tray.
(1)Make sure the machine is turned on.
(2)Lift the Scanning Unit (Printer Cover) until it 
stops.
The Paper Output Tray will open automatically 
and the Print Head Holder moves to the center.
Important
Handling Ink
zTo maintain optimal printing quality, we recommend the use of specified Canon brand clear ink 
tanks.
Refilling ink is not recommended.
zOnce you remove a clear ink tank, replace it immediately. Do not leave the machine with the ink 
tank removed. The machine does not operate without the clear ink tank installed.
zDo not replace the clear ink tank until the message informing you that the ink has run out is 
displayed. If the clear ink tank is replaced before it runs out of ink, the machine will be unable to 
accurately inform you when it is time to replace the tank.
zReplace an empty tank with a new one. Inserting a partially used ink tank may cause a 
malfunction. Furthermore, with such a tank, the machine will not be able to inform you when to 
replace the tank properly.
zOnce a clear 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 a clear ink tank within six months 
of first use.
Important
When replacing the clear ink tank, make sure that the machine is turned on. If the ink tank is 
replaced when the machine is turned off, the detected ink level may not match the actual ink 
level. 
CautionzIf the Document Cover is opened, you cannot 
open the Scanning Unit (Printer Cover). Be 
sure to open the Scanning Unit (Printer Cover) 
with the Document Cover closed.
zDo not hold the LCD.
zDo not hold the Print Head Holder to stop or 
move it.
zDo not touch the metallic parts or other parts 
inside the machine.

laws and regulations regarding disposal of 
consumables.
ImportantzDo not shake ink tanks as this may cause the 
ink to leak out and stain your hands or the 
surrounding area.
zDo not squeeze the side of the clear ink tank as 
this may cause the ink to leak out and stain 
your clothes and hands.
zThough the clear ink is clear liquid, be careful 
not to stain your clothes and hands with ink on 
the removed protective film.
zDo not touch the open ink port once the 
protective film is removed, as this may prevent

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 all the lamps on  the Operation Panel have gone out.
(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 all the lamps on the Operation Panel go 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.
If you have not used the machine for a long time,  print out the nozzle check pattern to check the 
print head condition before printing. See “Printing the Nozzle Check Pattern” on page 114.
„ Inks Are Stirred on a Regular Basis
The machine automatically stirs in ks to achieve maximum printing results. Therefore, printing on 
a regular basis helps keep  the inks in good condition.
When the machine is not used for an extended per iod of time, the machine automatically stirs 
inks when the machine is turned on. If automatic  ink quality maintenance is disabled, the inks 
may separate, resulting in uneven densities. Be  sure to follow “Performing Ink Quality 
Maintenance Manually” on page 122 before printing. Fo r details, refer to “Device Settings” of the 
User’s Guide  on-screen manual.
Note
zInk may blur depending on the paper in the following cases:
– Printed area is traced with a highlight pen or paint-stick
– 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 113. 
						

							113
Routine Maintenance
When Printing Becomes Fain t or Colors Are Incorrect
When printing becomes faint or colors are incorrect  even if ink remains in the ink tanks, the print 
head nozzles are probably clogged. Print the nozzle c heck pattern to confirm the condition of the 
nozzles and then perform Print Head Cleaning.
If print results are not satisfactory, performing Print Head Alignment may improve print quality.
z If the Ruled Lines Are Shifted
Note
Before performing maintenance
zOpen the Scanning Unit (Printer Cover) and make sure that all lamps for the ink tanks are lit red.
If not, see “Getting the Color or Black Ink Status Information” on page 103 and take the appropriate 
action.
z Increase the  Print Quality  setting in the printer driver settings.
For details, refer to the  PC Printing Guide on-screen manual.
Step 1
See “Printing the Nozzle Check Pattern” on page 114.
If lines are missing or if white streaks appearAfter cleaning the 
Print Head, print 
and examine the  nozzle check  pattern.
Step 2
See “Print Head Cleaning” on page 116.
If the problem is not resolved after performing Print Head Cleaning twice
Step 3
See “Print Head Deep Cleaning” on page 117.
Note
If Print Head Deep Cleaning does not resolve the problem, turn off the machine and perform another Print 
Head Deep Cleaning after 24 hours. If the problem is still not resolved, the Print Head may be damaged. 
Contact your Canon service representative.
See “Aligning the Print Head” on page 118.
Note
You can also perform the maintenance operation from your computer. For details, refer to the  PC Printing 
Guide  on-screen manual.
