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.

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. 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.
Printing graphics with the Intensity setting set too high.
