Cause Action
Ink tank is empty. Open the Top Cover of the printer to confirm how the ink lamps light or flash,
and then take the appropriate action depending on the error condition. For
details, see “Getting the Ink Status Information” on page 23.
The protective film is remaining. Make sure all of the protective film is peeled off and the air hole is exposed, as
illustrated in (A). If the orange tape is left as in (B), pull the orange tape and
remove it.
(A) Correct
L-shaped air hole is exposed.
(B) Incorrect
The tape is not peeled off.
Print Head nozzles are clogged. Print the nozzle check pattern to check for uneven ink output.
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 29.
z If the nozzle check pattern does not print out properly
Check if any of the missing colors are due to empty tanks.
If there is plenty of ink and the printer does not print, clean the Print Head
and then print the nozzle check pattern to check that ink is ejecting properly.
z If the problem is not resolved after performing Print Head Cleaning
twice
Perform Print Head Deep Cleaning.
If the problem is not resolved after performing Print Head Deep Cleaning,
turn off the printer and perform Print Head Deep Cleaning again after 24
hours or later.

Cleaning twice
The Print Head may be damaged. Contact your Canon Service
representative.
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 manual supplied with the paper for detailed information
on the printable side.
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 38 and perform Print Head
Alignment.
Cause Action
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 “Using Specialty Media” on page 4.
