We are using Workcentre 6515 DN on Mac OS X High Sierra 10.13.
When we want to print duplex from InDesign, pictures are not aligned from one page to the other.
We have tried all setting Center, vertical center, horizontal center, ... Never aligned as you can see in transparency on the picture; also on the cutting marks.
Is there a solution to be able to have the square perfectly aligned or Workcenter 6515 is not just pro enough for such a job (like with photography color printing quality)?
Thanks for your support
