A method for performing duplex printing with improved throughput has been developed. The method includes forming an image of a back side of a first duplex page and an image of a front side of a second duplex page on an image receiving member. Two recording media sheets are serially passed through a nip to transfer the image of the first duplex page back side to a bare side of a recording media sheet that also bears the image of the front side of the first duplex page on an obverse side and to transfer the image of the second duplex page to a bare side of a recording media sheet that has not been previously printed.

Print process for duplex printing with alternate imaging order

A method/printer prints images on an 'A' side of a first sheet of media and on an 'A' side of a second sheet of media in a single full transfer rotation of a drum. The method then prints images on the B side of the first sheet and on an A side of a third sheet in a single full transfer rotation of the drum. Similarly, the method prints images on the B side of the second sheet and on an A side of a fourth sheet in a single full transfer rotation of the drum. This method then prints images on the B side of the third sheet and the B side of the fourth sheet in a single full transfer rotation of the drum.
