I have the FB500 and I bought it back in April for wholesale printing coro signs, foam board, pvc and other stuff. I also use it a lot for banners because even though I prefer the print quality of my solvent and latex printers, a banner doesn’t have to be photo quality so it’s unbelievably faster to print on the FB500. I can print 8’ banners in under 10 minutes and I can print 100 double sided yard signs in under 2 hours. Even at $3.50 each running full color double sided (wholesale price) there is plenty left for gross profit after paying someone to feed it and the cost of ink. I am hoping to find an FB750 in the next 6 months once I find room for it.
Also, I have the roll to roll kit on my printer and I use it for heavy rolls but would not have paid the crazy fees they have for it if I had bought this machine new. I run plenty of roll to roll stuff on here without using the kit but note that without the takeup system, you are running everything into the floor.
One other thing, I intended to print white with this printer and have had it installed since April. It has been nothing but a money pit on that area. When running white ink, it runs printhead service every 30 minutes or more. I run 3rd party ink on mine and even with that, it costs me $7.00 per day in ink just for head cleanings. Now that this box of white is about finished, I’m switching it back out to Lm and Lc to save money and time. While in white mode, it often has to do cleanings right before or after a print, costing me time of standing still waiting on it. Definitely not worth it.
