I heard though the grapevine that since the Magenta channel was the most clogged channel on the 3800, they changed the Magenta chemistry to fix the issue and called it Vivid Magenta… so the 3880 should clog a LOT less than the 3800 for that channel.
I had a 3800 that had permanent clogs, and I now have two 3880 without any issues so far.
