Hello everyone we are obviously a new member here and by the looks of everything here, there seems to be a lot of knowledgeable people on this site I am very happy that we found it..I have a question I'm hoping someone can help me with. I run a older Nur Expedio 5000 and we have been having issues with banding and also missing nozzles. I purge the machine and the magenta and black will be fine for about 5-10ft then it will drop out again. I have tried to flush the head with UVD flushing solution. The UVD comes through the head just fine. But like I stated it drops out after a few feet. Here are some pictures of the test patterns. Any information would be helpful. Thank you
