Hi,
I have printed with my Epson 4800 for the past few years and everything has been fine until recently. The prints still come out looking great as well as the nozzle checks except for a horizontal 1/8" black line that is printed in the center of the image. I have run nozzle checks as well as power cleanings, updated the firmware and have moved the carriage and cleaned the area where it sits, but I am still getting the same black line on all of my prints. I have attached an image of one of the nozzle checks as an example. Any ideas on how I can fix this would be greatly appreciated.
Thank you,
Daniel
