P20000 owner here, 1 year in.
Love it. Zero head problems. I can turn on after weeks away and get a clean nozzle check, Canon-like (I own canons too)
Sure, I have occasionally had to do a random nozzle clean, but that's it.
That said, I did buy the 2 year warranty, as you never know.
Great output. incredibly fast. I'm a solo photographer-printer using it just for my own work, and thought speed didn't matter, but now I realise it does make life a lot easier!
For fine art output, the improved longevity of the Yellow is a huge gain. It was the weak link in the old generation.
3 of my friends have it too, and they are also happy.
I only wish they made a bigger machine - 24, 44, 64" exist, but go to any major museum/art fair and you'll see that an 84" one is very much needed.
