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 manual supplied with the paper for detailed information
on the printable side.
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.

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 "Media Types You Cannot Use" on page 9.
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, refer to "Changing Intensity Setting" in the User's Guide on-
screen manual 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.
