Good afternoon. I have a Canon Selphy 1500. My printer is printing just half of images in size 2 X 2 inches. Also, I am only getting yellow and red colours. The message on the screen reads as follows: There is a problem with the ink cassette.Turn the printer off, remove the cassette, tighten the ink sheet, replace the cassette and turn printer on again." I have done all of that several times. I have changed two cassettes. How does one tighten the in sheet and is there another solution in this problem.
Thanks
