I'm tempted to set up something in my home automation to print a "test" page every week or two, just to make sure it doesn't get clogged. Given the couple of feet of tubing between the tanks and the head, I suspect once that gets dried/gunked/blocked, it's game over.
This reads like actual gaslighting. Most users will never reach parts end of life? How is that even possible? Do most users buy a new ecotank printer and throw away their old one every year?
