Solution
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 printer is on.
2. Press the Open button to open the Paper Output Tray and extend the Output Tray Extension.
3. Open the printer properties dialog box.
4. Start Print Head Deep Cleaning.
(1) Click the Maintenance tab.
(3) Select the ink group to be deeply cleaned.
When cleaning the nozzles of black ink tanks: Select Black to clean the nozzles of PGI-5BK, Color to clean the nozzles of CLI-8BK.
(5) Confirm the displayed message and click OK.
Print Head Deep Cleaning starts when the POWER lamp starts flashing green.
Do not perform any other operations until Print Head Deep Cleaning finishes. This takes about 90 seconds.
REFERENCE
Clicking Initial Check Items displays the items to be checked before deep cleaning.
5. Check the condition of the Print Head.
(1) Load a sheet of A4 or Letter-sized plain paper in the Rear Tray or Cassette.
(2) Press the Paper Feed Switch to select the paper source in which you loaded the paper.
(3) Print the nozzle check pattern to check the print head condition.
If a particular color is not printed properly, replace the ink tank of that color.
(4) If the print head nozzles are still not clean, turn off the printer and perform another Print Head Deep Cleaning after 24 hours.
(5) If this does not solve the problem, the Print Head may be damaged. Contact your Canon Service representative.
