We just got a Xerox 7760, replacing an old 7700 that finally gave out. We've been running 7.2 on Tiger without any problems to the 7700. When we installed the 7760, we kept getting the SEF/LEF errors, or it scales everything up huge and prints on 11 x 17. We narrowed it down that the auto paper selection was causing the problem. Our work around has been to click the printer button and choose the "Paper Feed" option. From there, we choose the output tray we need to have our work come out on and then proceed to print the job. So far, it has been working. Every other program but Quark 7.2 will print without first having to select an output tray. One drawback to this method, besides adding steps, is that if you print to specific tray and it's out of paper, it will not automatically switch to another tray and continue printing the job.
