I have a very weird problem occurring when I run a 330mm by 487mm sheet on my xerox machines. On the versant Im getting what looks to be a piece of registration code in the same place on every sheet. A similar mark occurs when I run the same large sheet size on the 800, however, its only on the last page. It happens with different files, so its not the files. If I print on an SRA3 sheet size it goes away. However, I need the extra length of the sheet for certain jobs and I must use the larger sheet. Any help would be great. My technicians are stumped
