Thanks so much for the help guys, problem fixed!
On my plotter - CE5000-60 - it only has the "Roll 1", "Roll 2", and "Sheet" options as skarekrow alluded to. I kept looking for "Page" somewhere all afternoon yesterday haha I'm not sure what what the difference between Roll 1/2 are, but I put it on Roll 1 and it declined to unroll the vinyl i was using into the other room...for the first time in forever!
Thanks again for the quick responses!
