I am having issues with skewing. I am printing 2 up tri-folds -2 sided on 100# glossy text. I have run the tray alignment many times. After the alignment I run my print and it doesn't line up. It is off about 2mm on half the sheet. I get it as close as I can, then let it run. This wouldn't be a huge issue, except for the fact I then tri-fold them. Half of the print turn out ok and the other half are about 2mm off. I adjust the folder to split the difference, but I'm just not happy with it. Any recommendations would be helpful. Thanks.
