I have a problem with our 6500 printing 'off square'.
Printing on A3 the long edge of the sheet is square, while the short edge is off square by 2mm at both ends of the sheet. The problem is the same when I copy or print from creo.

Thanks

Are you familiar with carrying out the adjustments at the bottom of the machine tab?

From the service manual. You need a 30cm steel rule to carry out this adjustment properly. You may also have to adjust the CD Skew.
Do you not have a service contract on this machine? Where in Morpeth are you?
