Epson WF-7620 prints blurry every 7 lines black ink only
Epson WF-7620 prints blurry every 7 lines only when using black ink.
I have the same problem. I appears to be a driver issue. If I print from the Epson i-print app from my phone, it prints fine. Printer worked well on Windows 7 computer. Upgrade to Windows 10 is the problem. Driver doesn’t seem compatible with Windows 10.
