Geschiedenis van "How to fix printhead"

When I try to print  something it comes out all blurry and missing areas. I’ve performed the clean header function a few time  using up all my ink.  Is it possible to take it apart and clean the header, or should I buying more ink in hopes that the on board cleaning function will fix it ? I just don’t want to waist to much time and money on something that may not be  worth it
