QTR-Quadtone RIP

Running OSX 10.3.9, printing using QTR on 17x22 centered paper.  The printing starts 
just fine and then about 1/3 into the print it stops, backs up to the top of the page, prints 
out some very light banding, skips down to the middle of the page and says it's out of 
paper.  Does anyone have a clue as to what is going on?

thanks,

Jim
