Hi guys, just new here. Anyone who encountered this problem before, please share your knowledge what might be the cause and might the next step to do. This is a 4 months old print head and the attached image is the test print after done flushing the head. Done checking all the 4 head cables,trailing, linear encoder strip cleaning, fuses continuity check, linear and grit encoder sensor dry wiping/blowing, damper sucking. I'm confused what s the next step to do that might not create additional problem. Please, need HELP.
