At first my Cyan would not print on the print quality page. i have changed all the ink Cartridges. I have ran the alignment and head cleaning process many times. The alignemnt fails and i have unplugged the power from the printer. I read where i could clean the print heads manually. i did this per the directions and the cyan started printing good on the print quality page. But now the Yellow and the Magenta do not print on the quality page. i took the print heads out and shook them a couple times and all four ink colors came out.
what do i need to do or what might be the problem.
