This may be old info, but I had a job yesterday doing this very thing. Everytime I would clear a jam, load paper, unload the tray, etc. no start button. Another way I found to get the job going, assuming you have Fiery, is to 'suspend printing' for about 10 seconds at the server then click 'resume printing.' Got the job going again exactly where it left off. And considering it was variable data, that is crucial! Hope this helps!
