Latex 3600 - Double-Sided Printing

When printing double-sided on the 3600 a registration line is printed while printing Side A. What is the default margin in inches that is added to the job when the registration line is added?

Hello @thomaritch

On the IPS when you change the type of job, and you select the feature Double side the job length increase 3cm per copy. (1 inch as default margin plus the black line about 5mm).
