Finisher on Color 560 not folding the correct fold
I'm attempting a 4/4 8.5"x11" trifold project on my Color 560. I run everything through the Fiery software on my Mac OS 10.11.3, and tell it to make a trifold. It comes out as a Z fold, but it's not even a correct Z fold. The second fold leaves the back edge with an inch and a half of paper outside the folded area (not folded symmetrically).The settings in Fiery have been triple checked and are correct. I don't know what to do to even begin to fix this. I've tried different papers/weights which had no effect.
We ran a job similar to this last week, with no issues. I don't know what has changed. Same settings.
