Just finished up the first of these! some logistic issues (getting ink/heads shipped on time, but had time to spare), but the machine was cranking through product the 3rd day. End user had 1 other issue today with a motor controller, but CET got him resolved on that.
The one I set up is a X-Press 100 (Spectra CMYKWx2) Z (5x10). on a 4x8 board, we were printing excelletn quality at nearly 500sqft/h. I believe the software said 486. This was 600x1200 (6pass) bi.
I hope your install goes as well!
