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.
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.
Make sure all of the protective film is peeled off and the air hole is exposed, as

remove it.

See "When Printing Becomes Faint or Colors Are Incorrect" on page 114 and
perform any necessary maintenance operation.
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 119 and perform Automatic Print
Head Alignment. If this does not solve the problem, see "Manual Print Head
Alignment" on page 120 and perform Manual Print Head Alignment.
See "When Printing Becomes Faint or Colors Are Incorrect" on page 114 and
perform any necessary maintenance operation.
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. See "Paper Handling" on page 21.
Especially if you are using plain paper to print images with high intensity, the
paper may absorb too much ink and become wavy, causing paper abrasion.
When copying, see "Making Copies" on page 35 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.
