Print Results Not Satisfactory
If the print result is not satisfactory such as  white streaks, misaligned lines, and uneven colors, 
confirm the paper and print quality settings first.
z Check 1: Do the page size and media type settings match the size and 
type of the loaded paper?
When these settings are incorrect,  you cannot obtain a proper print result. If you are printing a 
photograph or an illustration, incorrect paper type  setting may reduce the quality of printout color. 
Also, if you print with an incorrect paper type  setting, the printed surface may be scratched. In 
borderless printing, uneven coloring may occur depending on the combination of the paper type 
setting and the loaded paper.
z Check 2: Did you set the print quality setting appropriately?
Select a print quality option suitable to the paper and image for printing. If you notice blurs or 
uneven colors, increase the print quality setting and try printing again.
* When printing from a PictBridge compliant devic e, set the print quality setting by using the 
Operation Panel on the machine. You cannot ma ke this setting from a PictBridge compliant 
device.
The method to confirm the paper and print qualit y settings differs depending on what you do with 
your machine.
z Check 3: If the problem is not resolved, there may be other causes.

CauseAction
The media is loaded with the wrong 
side facing upwards. When using paper with one printable surface, make sure that the paper is 
loaded in the Rear Tray with the printable side facing up or in the Cassette with 
the printable side facing down.
Printing on the wrong side may cause unclear prints or prints with reduced 
quality.
Refer to the instruction manual supplied with the paper for detailed information 
on the printable side.
Ink tank is empty. See “An Error Message Is Displayed on the LCD” on page 133 to identify the ink  error, and then take the appropriate action depending on the error condition.
Paper is not loaded in the appropriate 
paper source. Load any type of paper other than plain paper in the Rear Tray, and plain paper 
in the Cassette for printing. Make sure that the selected media type and paper 
source are correct. For details on loading paper, see “Loading Printing Paper” 
on page 20.
Print Head nozzles are clogged. See “When Printing Becomes Faint or Colors Are Incorrect” on page 113 and  perform any necessary maintenance operation.
Print Head is misaligned. If you did not align the Print Head after installation, straight lines may be printed  misaligned. Make sure to align the Print Head after you install it.
See “Automatic Print Head Alignment” on page 118 and perform Automatic Print 
Head Alignment. If this does not solve the problem, see “Manual Print Head 
Alignment” on page 119 and perform Manual Print Head Alignment.
Inks have separated, resulting in poor 
or reduced print quality. Ink in one or more ink tanks has separated, resulting in uneven density. See 
“Print Head Cleaning” on page 116 and perform Print Head Cleaning. If the 
problem is not resolved after performing Print Head Cleaning twice, perform 
Print Head Deep Cleaning.
Be sure that the automatic ink quality maintenance function has not been 
disabled. Refer to “Device Settings” of the 
User’s Guide on-screen manual. 
Enabling ink quality maintenance is recommended. If this function has been 
disabled, see “Performing Ink Quality Maintenance Manually” on page 122. 
Failure to perform ink quality maintenance on a regular basis may affect print 
quality.
CauseAction
Print Head nozzles are clogged. See “When Printing Becomes Faint or Colors Are Incorrect” on page 113 and  perform any necessary maintenance operation.
CauseAction
Paper is too thin. When printing data with high color saturation such as photographs or images in deep color, we recommend using Photo Paper Plus or other Canon specialty 
paper. See “Paper Handling” on page 21.
Printing graphics with the  Intensity 
setting set too high. If you are printing images with high intensity, the paper may absorb too much ink 
and become wavy, causing paper abrasion.
When copying, see “Making Copies” on page 32 and reduce the intensity 
setting. Then try printing again.
When printing from your computer, refer to “Print Results Not Satisfactory” in the 
User’s Guide
 on-screen manual.

„Printed Surface Is Scratched/Paper Is Smudged
CauseAction
Printing on inappropriate type of paper.
zCheck to see if the paper you are printing on is not too thick or curled.
See “Paper Handling” on page 21 to make sure that the paper you are using 
is suitable.
If the paper is curled, see “Paper is curled.” on page 144 to correct paper 
curl.
z When performing Borderless Printing, print quality may be reduced at the top 
and bottom edges of the paper. Make sure that the paper you are using is 
suitable for Borderless Printing. 
For details, refer to “Printing Area” in the  User’s Guide on-screen manual.
Paper is curled. If you are using paper with either any of the corners or the whole printing  surface curled, the paper may become dirty, not feed properly, or both. Use such 
paper after correcting paper curl as follows.
(1)With the printing side (A) facing up, cover the paper with a fresh sheet of 
plain paper to avoid staining or scratching the surface.
(2) Roll up the paper in a direction opposite to paper curl as seen below.
(3) Check to see that the paper curl is within approximately 0.08 to 0.2 inches / 2 
to 5 mm (B) in height.
We recommend printing curl-corrected paper one sheet at a time.
NoteDepending on the media type, the paper may be smudged or may not be fed 
properly even if it is not curled.
In such case, follow the procedure described above to curl the paper before 
printing. This may improve the print result.
Printing on thick paper. Selecting the  Prevent paper abrasion setting will widen the clearance between 
the Print Head and the loaded paper. If you notice abrasion even with the media 
type set correctly to match the loaded paper, set the machine to prevent paper 
abrasion by using the Operation Panel on the machine or the printer driver.* 
* Deactivate the  Prevent paper abrasion  setting once printing is complete. If 
not, this setting remains enabled for all subsequent print jobs. 
z Setting with the Operation Panel on the machine  
Press the  Menu button, select  Maintenance/settings , Device settings , and 
Print settings  in this order, and then set  Prevent paper abrasion to ON . For 
details, refer to “Device Settings” in the  User’s Guide on-screen manual.
z Setting with the printer driver  
Refer to “Print Results Not Satisfactory” in the  User’s Guide on-screen 
manual.
