Alright, another UCJV300 user! Hours on those aren't printing hours, but you definitely got a bit of square footage on the thing. Thankfully, the printers are great in my experience. Got a 2016 model myself, so really early production and it lacks the curse of most early versions. With how silly easy it is for dealers to adjust the hours/sqft on the parameters, I rarely count on low numbers being that accurate. Main thing with any printer is how good it prints and the uptime it has doing those prints. Right now, the UCJV300s are pretty much being sold out for the newer UCJV330 series. Since it's still a brand spanking new model, probably good to avoid until the issues that new printers tend to have been worked out.
What inkset are you using? Can have lots of stupid fun with white/clear inks doing things like texturing, special art with backlighting, double-sided prints on clear media, etc. If running double CMYK, the things run pretty quick as well. Never used the light cyan/light magenta set myself, but the extra color can help. We do lots of promotional type items with ours, small batch items and outdoor decals and the like. We have REALLY good luck with the LUS-170 ink (Mimaki and aftermarket) without even needing to laminate. When we feel like going extra cheap, we just snag up ink that's a few months out of date and still have great results. Probably not a great idea of on a lease though, but we got ours dirt cheap and we like to abuse it.
