I don't have a Ricoh, but on my Fiery, it is under the layout tab, called "Flip". However, I noticed that feature is not available for imposed jobs. If that is your situation, the workaround is to save it as a new flattened PDF instead of a .dbp file. (I have CWS 6.3)I searched the Fiery help files & mirror is supposed to be in the "Layout" tab, It's not showing as an option on our RIP.
