I also had magenta inks spotting the print, it happened only some of the time. epson did replace the printer after having me adjust the thickness gap, which did not work.
To add to the story they twice sent refurbs which arrived damaged as they are not packed as well as new units, The 3rd time they sent out a new unit which arrived in fine condition.
I am starting to get ink leakage on my prints. They appeared on the side at 1st but there are tiny dots all over the page now. I have had this printer for less than a year and I have been always using original cartridges. Anybody has experience with this? I tried powering down, auto head cleaning, but no go.
