I just got an Epson HD XP-15000 and after 2 days of testing and using lots of ink and paper I finally got it to make good prints for an upcoming exhibit. The color and contrast look good but the print stops moving at the end and the ink head keeps moving over the print and creating a green band about 1/8'' wide at the very end. Does anyone have an idea as to why this is happening now after 2 days of printing without it? Thank you for any info on this.
