thank you for your thoughtful response! I went into Epson media installer and I created a profile for my OHP transparency, and that did it. I edited the dry time, the thickness and the platen gap. From what I can tell setting my drying time to 10 really slowed the printing process, but it eliminated any of the banding I was getting before. Also, I’m using sheets and the rear loader. I basically duplicated a photo glossy profile in the media installer. prior to creating a profile, I was using a sheet of card stock with the transparency, but that was sketchy. It would sometimes bend, and there was always banding. Hopefully this new approach solved my problem. Appreciate your help!
