Clean the Print Head and then print the nozzle check pattern to check that 
ink is ejecting properly.

perform Print Head Deep Cleaning again.

If the problem is still not resolved after performing Print Head Deep 
Cleaning twice
A FINE Cartridge may have run out of ink. Replace it with a new one.

For details on how to print the nozzle check pattern, how to clean the Print 
Head, and how to perform Print Head Deep Cleaning, see “When Printing 
Becomes Faint or Colors Are Incorrect” on page 14.

The media is loaded with the wrong 
side facing upwards.

Many types of paper are made to be printed on only a particular side of the 
paper.
Printing on the wrong side may cause unclear prints or prints with reduced 
quality.
Refer to the instruction manuals supplied with the paper.

Print Head is misaligned.

If you did not align the Print Head after installation, straight lines may be printed 
misaligned. If ruled lines are printed misaligned or print results are otherwise 
unsatisfactory, see “Aligning the Print Head” on page 23 and perform Print Head 
Alignment.

Print quality is not set appropriately.

Set the Print Quality setting to High in Windows or Fine in Macintosh.

(1) Open the printer properties dialog box.

Refer to “Opening the Printer Properties Dialog Box from Your 
Application Program” in “Opening the Printer Properties Dialog Box 
(Windows)” of the User’s Guide on-screen manual.

(2) On the Main sheet, click High for the Print Quality setting.

(1) Open the Print dialog box.

Refer to “Opening the Print Dialog Box” in “Opening the Page Setup and 
Print Dialog Box (Macintosh)” of the User’s Guide on-screen manual.

(2) Select Quality & Media in the pop-up menu and then click 

Detailed Setting.

Depending on the type of paper, you may not be able to set Print Quality to 
High (Windows) or Fine (Macintosh).

Paper is too thin.

When printing data with high color saturation such as photographs or images in 
deep color, we recommend using Photo Paper Pro or other Canon specialty 
paper. Refer to “General Information” in the 

 on-screen manual.

Media Type setting in the printer driver 
does not match the actual type of 
paper.

Make sure that the Media Type set in the Main sheet of the printer driver 
(Windows) or the Quality & Media in the pop-up menu of the Print dialog box 
(Macintosh) matches the type of the loaded printing paper.
