I have a RX580 Epson printer and I'm getting horizontal lines about an inch apart on my prints.My ink level was low in a couple of the cartridges so I replaced them today thinking that may be the problem,when that didn't fix it I did a head allingment and head cleaning as well as a nozzle check.After a few test prints a cartridge that showed 40% is now low and since I live 2 hrs down a logging road I won't be able to replace it soon.Could the now low cartridge be the problem or is it something else.I tried printimg from Elements 6 and LR but both had the same poor results.
When I first got this printer I had the same problem printing from DPP but elements worked fine,until now.
