A shield assembly is provided for use in combination an ink jet printer and is operative to provide a smooth planar surface for printing on a print media. The described embodiment includes a shield having first and second contact surfaces to define an opening therebetween. The opening of the shield assembly is aligned with the print head of the ink jet printer for permitting the deposition of ink through the opening. The assembly further includes a pivot mount operative to pivot the shield about a rotational axis which is substantially parallel to the feed path of the print media and orthogonal to the motion of the print head. Moreover, the assembly includes a means for pivoting the shield about the rotational axis in a first and second direction thereby causing one of the contact surfaces to engage the print media upstream of the print head when depositing ink on the print media.
