Print Head Deep Cleaning - Canon PIXMA MX700 Series Quick Start Manual

Print Head Deep Cleaning

If print quality does not improve by standard Print Head Cleaning, try Print Head Deep Cleaning,
which is a more powerful process. Note that cleaning the Print Head causes used ink to be absorbed
in the ink absorber. Print Head Deep Cleaning consumes more ink than standard Print Head
Cleaning, so perform this procedure only when necessary.
1
Make sure that the machine is turned on, open the Paper Output Tray, and extend
the Output Tray Extension.
2
Load a sheet of A4 or Letter-sized plain paper in the Rear Tray or the Front Tray.
3
Press the Feed Switch button to select the paper source where you have loaded
paper.

5
Check the condition of the Print Head.
(1) Print the nozzle check pattern to check the print head condition.
See "Printing the Nozzle Check Pattern" on page 87.
If a particular color is not printed properly, replace the ink tank of that color.
See "Replacing an Ink Tank" on page 80.
(2) If the print head nozzles are still not clean, turn off the machine and perform another Print
Head Deep Cleaning after 24 hours.
(3) If this does not solve the problem, the Print Head may be damaged. Contact your Canon
service representative.
