If all you need is a basic roll to roll solvent printer, the 300 series are rock solid, and dual head for that speed you want.
I run a CJV300+, I have external cutters, so I never use the one on the printer, but it's always there as a backup cutter if I ever need it. Of all the printer brands & models I've run over the years, it's been the most reliable solvent roll to roll. Excellent quality, good speed, not a lot of maintenance to keep it running good. The plus uses the 600ml ink bags, which are cheaper than the 440ml cartridges. It uses almost no ink in the refresh cycle, which is all I've ever used instead of the auto cleaning. Every time it shows the waste ink should be 80% full it's always almost empty, last 5 times I've just reset it and go, waste bottle still isn't half full, so there's very little ink waste. Wife was in the hospital recently, left it for well over a week, ran a test print expecting the worst, it was perfect, had zero dropouts or issues. That's the kind of stuff you usually can't do with solvent printers, especially one that's a few years old already. They're good machines.
