Printer: HP Photosmart 5520 e-All-in-One
OS: Windows 7 Home Premium
I bought this printer a few months ago and didn't use it too much. Before issue happen, never change anything. It suddenly had issue to print colored pages properly. I've checked the ink level, all are still ok, I cleaned the printerhead as per the guide from this forum, problem still persist. All the ink and A4 sized paper are from HP original. Below is the print out of the "quality check page". Can someone please advice what happened and how to solve?
Thanks!
