Abstract
A printing apparatus places multiple images on a sheet 10, at least once on one side, and at least once on an opposite side. After the first printing, the sheet 10 is inverted by an inverter 50 and sent to a duplex path 42. Sensors 20, 40, both in a feed path 22 and the duplex path 42 detect the side edge of the sheet 10 to register the position of the sheet 10 to an image rendering device 14. A user has the option to input preferences at a user interface 26, the preferences including running average and registration options. More specifically, the user has the option to choose a number of sheets 10 used to calculate a running average for registration of both the simplexed and duplexed sheets 10. The user also has the option to select between image to image registration, and image to page registration for duplex printing.
