Hello people,I have had my Frontier 500 for a decade now,and I have always been gratefull for how well it worked for me,until lately,when I print a photo,there is white line that cover the photo in traces(Ill link the photos bottom). Did anyone had a similar problem,or does someone know a solution to it? I would be really happy to solve that problem,since Im making a living out of my Frontier 500. Thanks in Advance

P.S. Here is the photo.

That's a processor rack line.

 

Remove all the racks and give them a clean.

Clean the tanks too.
