Abstract: A method, non-transitory computer readable medium and apparatus for reducing contamination on a decurler in a printer are disclosed. For example, the method includes printing, by a marking engine, an image on a paper on a first side, inverting, by a first inverter, the paper so that the image on the first side is facing in an opposite direction than when passing through the marking engine and decurling, by the de-curler, the paper such that the image on the first side contacts a soft roller of the upstream de-curler.
