ABSTRACT:
A paper guide includes a wing that extends over a respective lateral edge of the print media and a dimple formed on a bottom side of the wing that contacts the print media between the respective lateral edge and an edge of the maximum printable area. The dimple separates the print media from the wing so as to avoid smearing the ink in the maximum printable area. Two embodiments of the dimples are shown. A first embodiment of the dimple includes a central elongate portion having first and second hemispherical portions at respective ends thereof. The second embodiment is a substantially semi-hemispherical shaped dimple. The second embodiment can operate either by itself or in conjunction with a second substantially identical semi-hemispherical dimple.
