Hi,

I am Himadri..

If you get this error message "The type of print head is incorrect. Install the correct print head." then follow the steps below to remove the print head and reseat it and let me know.


Remove the Ink Tanks

  1. Confirm that the printer is powered on and open the paper output tray.

  2. Lift the scanning unit (printer cover) completely. (The print head will move to the replacement position.)

    N.B.: When the scanning unit (printer cover) is opened more than ten minutes, the print head moves to the right side. If this occurs, close the scanning unit (printer cover), and open it again.

  3. Remove the ink tanks by pressing the tab of each tank.

    Caution: Handle the ink tanks with care so that your clothes and surrounding area do not get soiled. Make sure to remove the ink tanks one by one.

As I said in the question I HAVE NOT CHANGED THE PRINT HEAD the one in the machine is the origional, it was printing fine this morning and then I got the error message

Expert:  hsroy79 replied 1 year ago.
The print head is defective and the printer cannot detect the print head.Replacing the print head will resolve the issue.If the printer is less than one year old then the print head will be replaced free of cost from Canon.
one more solution before replacing the print head.Please remove the print head and then clean the copper contacts on it with a cotton swab dampened in distilled water and after drying try to use the print head if the problem persist then replace the print head.
