Haven't thought about the details yet, but i would have the paper leading  
edge detector applied directly to that table.

If possible i plan to have this table engaged with the feed rollers all  
the time - i don't see this as a sheet you feed like thick paper, i see  
this as a flatbed printer - gantry style.

If it takes some fooling of the mechainsm (sensors, taking over control of  
motors at times), then that's what it takes...
