We purchased an HP FB550 in December of 2018, so it is just over 2 years old. It has been a bit of a lemon. We have had thermistor issues, encoder strip issues, but the final straw was an ACM headstrike we had last week. It was our fault (damaged leading edge on ACM) and it lead to the head dragging across the ACM, which seemingly ruined 6 or so heads. It is going to cost us $16,000+ to have them replaced by HP ($6,000 for labor and travel time) and they are taking their sweet time getting the ball rolling. (For anyone wondering how hard we worked to get the existing heads back, we cleaned them, soaked them overnight from the bottom with lint free cloth soaked in head flush, emptied the heads, filled them 2/3 full with head flush, ran 20+ purges, did an automatic jet nozzle mapping, ran countless jet replacement prints, etc., so if there are other tips and tricks that might help cut our losses, I'm all ears!!!)
So, I spent roughly $90K on this machine a little over two years ago. We like our two HP latex roll to roll printers, but this flatbed has been a huge disappointment. I am considering replacing this one in a few months with another brand, but I don't know anything about the other manufacturers and their machines. We primarily do ACM and coroplast, but we also print on some thin .020 and .040 rigid polystyrene. What recommendations do you have for a really dependable flatbed? It doesn't have to be a speed demon, but it also can't be too slow. Any recommendations and advice are greatly appreciated!
