In this video I will walk through the steps I took to replace the printhead in my Roland BN-20. In the steps leading up this this video I had been advised that I may need to have the new printhead's "Head Rank" input to get the best quality print. As a non-Roland tech, I do not have the "Service Application" to do so. With that in mind but my machine was down I went forward with the swap after watching the video by "Khristy Bell". I definitely give her props for pure determination. After all of that, I did it and didn't even need the Roland "Service Application". My BN-20 prints better than ever.
