Perfect product for the error message you get on your EPSON printer
Top tier product. This pad replacement came with the instructions on how to fix my Epson printed that I've converted into sublimation. I never knew it had a drip container and I literally thought I was going to have to spend a lot of money trying to fix it. I looked up some videos and saw i needed a replacement kit. THis is it is I have an epson 4800 the video walk through with the paper was EASY, to put it in was even easier. Highly recommend.
