"Adjust Lead/Side Registration" Setting Not Responding
Product Name: Phaser 7100
Operating System: macOS 10.13 - High Sierra
Would anyone know how to set the "Adjust Lead/Side Registration" setting in the on-printer menu? I have a Xerox 7100. I'm trying to double-side text-weight sheets and they are not aligned on front and back. If I change the setting to move the print image -2mm nothing happens on the resulting test print page. I hit the "okay" button to confirm the -2mm amount and the black dot appears next to it to confirm the selection. When I hit back after hitting okay, the setting doesn't stick.
Any ideas? I'm looking to move the print image over a tad. Thank you.
