For 2-sided printing, correct the misalignment between the [Front] and [Back] sides in order to align the printing positions of both sides. This operation is called [Both Sides Adjust].
At the time of printing, heat in the fusing section may cause the paper to slightly enlarge or shrink. How much the paper is affected depends on the type or weight of the paper; therefore, after changing the paper loaded in the tray, always perform the [Both Sides Adjust].
