Do a search for my name and GS6000, there's a mountain of info there too... I'd give you mine for free but then you'd come back and kill me and my family and my friends.
Some people have zero problems with them ever, others have nothing but problems and can hardly get a sellable print off of one. I fall into the latter category. We've had nothing, and I mean NOTHING but problems with ours. If it were out of warranty at this point we probably would have spent over $6000 on service calls and repairs. And we've had it for about 6 months. And that doesn't take into consideration the ruined prints from it, I don't even want to think about that.
It's expensive to run. It's not a production machine like our Mimaki printers, it requires too much babysitting. It's over engineered but still has a hard time pulling or rolling heavier media. It freaking drinks ink. Ink durability looks like it's going to be a major problem, we're hearing stories of unlaminated prints showing some fading within 6 months and in a year with laminate. The green ink is known to be problematic, it's already ruined one of our heads. It's proven difficult to get decent speed out of it while maintaining good print quality.
On the plus side, when it prints well, it prints well. But honestly, we can squeeze nearly the same quality and color gamut out of our JV33, and we can get that color and quality over twice as fast and for half as much, and we know it'll last longer.
I keep saying this, but I really regret buying it. But others love them and that's great. You may get lucky and get a good machine, and it may fit into your needs really well. For us, we got a bad one and as it turns out it's not a good fit for the demands we need to place on it.
