Sorry can’t help you with Flexi but I can advise you not to buy a BN20. Possibly the slowest most useless printer Rolands ever produced. No dryer, & has a stupid waste tank that needs replaced at 50 quid a pop (unless you screw it apart, empty it and fill it with sanitary towels 😉 One of our sales reps calls them the boomerang 20 as no sooner have they sold one it’s back for a trade in and upgrade.
If you can at all avoid it, I wouldn’t recommend a BN20. See if you can get a 2nd user Roland or Mimaki print / cut machine. I would also make sure that any machine you bought, would take a minimum of 760 wide rolls, otherwise you’ll probably struggle to get material. If you have space, get a 1370mm wide machine. For a Mimaki, you’d be looking at one of the CJV models for print & cut. I can’t advise on Roland models, as I’ve never had one, but maybe someone else could help.
Unfortunately Kev I haven’t really followed the different models since we changed ours. Previously we’d a Roland SP540 that was absolutely bulletproof. We printed hundreds of thousands of stickers on it without any problems whatsoever. The only thing it ever needed was regular maintenance & servicing. You can get the smaller SP300 but it takes a smaller roll which limits what you can print. You’ll be amazed how quickly your machine isn’t wide enough once jobs start to come in. We’re running 2x 64″ wide machines and still get asked for wider banners.
