Duplex-all pages print at "legal" speed. 4 Average duplex print performance measured under the following conditions: Simplex text document from the printer's integrated tray to the printer's standard output bin, with a job stream sufficiently long for the printer system to enter the maximum duplex print performance page sequence (2,4,6,1,3,5...) The first two sides (2 and 4) are not included in the performance computation since they "seed" the printer system's paper path to achieve the maximum duplex print performance.
