You can rotate faxes within the message center; any fax that is rotated is auto-saved. There is no need to hit save each time a rotation is set. Please view the below images to get a better idea of how this functionality works.
Go to the Message Center and select the fax.
You can rotate all the pages, an individual page, or a range of pages. Next click the direction of the rotation: clockwise or counterclockwise.
