It's a very good idea rodcones. One we have affectionately named "Holiday Mode". Basically a program, or firmwear update, that would fire all nozzles of all channels in appropriate sized blocks of color - set at a user specified maintenance schedule. Dry climates, or times of the year you fire it more often, rainy seasons (for instance) you fire it less. Apparently there is a way to do this now by using a program kdphotography has brought to attention a few times now - it's called Harvy Head cleaner. Ken mentions this program a few posts up from this one actually. It's pc based. I believe Ken sets his version up to do exactly what you mention, via a local laptop. For sure this would help. It would be great if Epson created a firmwear update with this feature. I brought it up with a tech on the phone about two months ago. His response was disheartening, "There's a problem with X900s clogging...?" this was followed by "you could email me about it, I'll forward it to my manager, then he can forward it to his boss. If they decide it's a good idea, and enough people ask for it, they would then have to forward it to the right people at Epson Japan. And then they would have to..." That sounds like a long road filled with ifs and buts to me. But it's definitely a great idea
