„ Replacing FINE Cartridges
When FINE Cartridges run out of ink, re place them using the following steps.
Note
Setting of FINE Cartridges
If a FINE Cartridge runs out of ink, you can set the machine to print with either Color or Black FINE 
Cartridge only for a while. However the same printing quality cannot be expected compared to 
when printing with both cartridges. Canon recommends to use new genuine Canon cartridges in 
order to obtain optimum qualities.
You should perform this setting without removing the empty cartridge. If the FINE Cartridge is 
removed, an error occurs and you cannot print regardless of the Ink Cartridge Settings.
For information on how to configure this setting, refer to the  Printer Driver Guide on-screen 
manual.
Important
Handling FINE Cartridges
z Do not touch the electrical contacts or Print Head Nozzles on a FINE Cartridge. The machine may not 
print out properly if you touch them.
(A) Electrical Contacts
(B) Print Head Nozzles
z To maintain optimal printing quality, we recommend the use of specified Canon brand FINE Cartridges.
Refilling ink is not recommended.
z Once you remove a FINE Cartridge, replace it immediately. Do not leave the machine with FINE 
Cartridges removed.
z 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.
z 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.
z 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 a FINE Cartridge is out of ink, replace it 
immediately with a new one.
z When a FINE Cartridge runs out of ink, you can continue printing with either Black or Color ink only by 
changing  Ink Cartridge Settings . For details, see “Setting of FINE Cartridges” on page 27.
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, the machine does not print.

(2) Push up the FINE Cartridge until it clicks into 
place.
5Close the Scanning Unit (Printer Cover).
Lift the Scanning Unit (Printer Cover) slight ly and put the Scanning Unit Support back to its 
original position.
Then close the Scanning Unit (Printer Cover).
The FINE Cartridge Holder moves to the right.
Important
The machine cannot be used unless both the FINE 
Cartridges are installed.
Note
z When you start printing after replacing the FINE Cartridge, Print Head Cleaning is performed 
automatically. Do not perform any other operations until Print Head Cleaning finishes.
z If the straight line is misaligned or the Print Head position is misaligned, align the Print Head 
position. See “Aligning the Print Head” on page 22.

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 20 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 If the printed area is traced with a highlight pen or paint-stick or stained with water or sweat, ink may 
blur depending on the paper.
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 18.

Cleaning Your Machine
This section describes the cleaning proc edures needed to maintain your machine.
„Cleaning The Platen Glass And Document Cover
Moisten a clean, soft, lint-free cloth and wring out  excess water. Wipe the Platen Glass (A), and 
the inner side of the Document Cover (white s heet) (B). Then wipe with another clean, soft, dry, 
lint-free cloth, making sure not to leav e any residue, especially on the Platen Glass.
„Cleaning The Exterior
Wipe the machine’s exterior with a clean, soft, lint-free damp cloth.
Caution
zBe sure to turn off the power and disconnect the power cord before cleaning the machine.
z Do not use tissue paper, paper towels, or similar materials for cleaning. Paper tissue powders or fine 
threads may remain inside the machine and cause problems such as a blocked Print Head and poor 
printing results. Use a soft cloth to avoid scratching the components.
z Never use volatile liquids such as thinners, benzene, acetone, or any other chemical cleaner to clean 
the machine; these can damage the machine’s components.
Important
The sheet (B) is easily damaged, so wipe it gently.

Routine Maintenance
„ Cleaning the Paper Feed  Rollers (Roller Cleaning)
Clean the paper feed rollers if paper is not fed properly. Cleaning the Paper Feed Roller of the 
Auto Sheet Feeder consumes it, so  perform this only when necessary.
1Make sure that the machine is turned on, and then remove any paper from the Auto 
Sheet Feeder.
2Press the Maintenance  button repeatedly until  b appears.
3Press the  Black or Color  button.
4Repeat steps 2 to 3 twice.
5Open the Paper Output Tray.
6Load three or more of A4 or Letter-sized plain paper in the Auto Sheet Feeder.
7Repeat steps 2 to 3 three times.
The paper cleans the inside of the machine as it feeds through the machine.
„Cleaning the Inside of the Machine
If the printed paper is smudged, the inside of the machine may be dirty. 
To always get best quality printing result, per iodical cleaning of the inside of the machine is 
recommended.
You can clean this part in two ways:
z See “Cleaning the Bottom Plate (Bottom Plate Cleaning)” on page 33.
z See “Cleaning the Protrusions Inside the Machine” on page 35.
z Cleaning the Bottom Plate (Bottom Plate Cleaning)
This section describes how to clean the inside  of the machine. If the inside of the machine 
becomes dirty, printed paper may get dirty,  so we recommend performing cleaning regularly.
1Make sure that the machine is turned on, and then remove any paper from the Auto 
Sheet Feeder.
2Fold a single sheet of A4 or Letter-sized plain paper in half widthwise, and then 
unfold the paper. 
Note
If there are no signs of improvement after performing the Roller Cleaning, contact a Canon service 
representative.
Important
When using Photo Paper Plus Double Sided PP-101D, be sure to clean the inside of the machine 
before printing.
