Art - I chatted with Xerox and they said the only way for it to work was if the job was 3 pages. They said they didn't have a way to staple every 3 pages within a job. They also have exception rules... where if we can get the job to be just 3 pages it can pull from tray 1, exception - tray 2, another exception - tray 3. The company in Germany you mentioned didn't reply, so that was a no go. I appreciate you checking on this for us.
