    Important
    Install all the ink tanks to print. The machine cannot be 
    used unless all the ink tanks are installed.
    Caution
    z Be sure to hold the Scanning Unit (Printer Cover) firmly using both hands, and be careful not to 
    get your fingers caught.
    z Do not hold the LCD.
    NotezIf the error message is still displayed after the Scanning Unit (Printer Cover) is closed, see “An 
    Error Message Is Displayed on the LCD” on page 133.

    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.

    2Remove the clear ink tank.
    (1)Push the tab and open the Clear Ink Tank 
    Locking Cover.
    (2)Remove the clear ink tank.
    3Prepare the replacement tank.
    Remove the orange tape in the direction of the 
    arrow to peel off the protective film from the clear 
    ink tank.
    ImportantzHandle ink tanks carefully to avoid spilling ink 
    or staining clothing or the surrounding area.
    zDiscard empty ink tanks according to the local 
    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 
    the ink from being ejected properly.

    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.
