I have 2 z3200s, one of which is awaiting my installation of a new fan and belt, and the other has an issue I've been unable to solve. Although they have been great machines for me, I have had issues for years with temperamental head strikes on dark prints on matte paper, causing me to run humidifiers and waste a lot of material on particularly hot, dry days in LA. After reading all the issues with the Z9s, I bought a Canon pro 4100 about 9 months ago and have not needed to run my humidifiers since. I think your humidity concern is in regard to clogging which I can't really speak to but I think that's more of an Epson issue. The Canon does have a replaceable printhead but it's one large one as opposed to 6 individual ones like the Z. It's early days on this machine for me but I would certainly have a look at Canon as well. I really wanted to stay with the Z series but I need to get up and running fast and the Canon delivered (although it is much bigger and heavier).
