I have been using the epson ecotank 2711 for 12m without issue until recently.
I use the mug paper from ink experts and sublinova inks
my issue is when printing a design I have to trim the edge off one end and the top or I end up with a thin black line down the mug from the printer leaving ink on the paper.
I have cleaned it a 1000 times. Without solution.
HELP!
