The prints got starting to have lines on the entire printed image(please take look at the attachment) after the tech guy installed the new head. The lines are same direction to move of the head, looks like nozzle check test.
I had this issue on smaller part of image before with another printer, also 7880. It was managed by changing the setting of the Paper Feed Adjustment, “-14” as Walker suggested. Now entire image got lines. I tried three types of baryta papers, and “Wide” & “Wider” platen gaps, and also “-14” & “-28” Paper Feed Adjustment. The results were same.
Here is one thing I concern… When the guy installed the head and got it fine tune with their professional software, he didn’t worked with a Epson paper, but Canson Baryta paper. It might got off the setting?
I am wondering how I can mange this issue.
