Abstract:
1. A printer comprising: a first media transport operative to receive a substrate media and to convey the substrate media into, through, or out of a marking zone of the printer, the marking zone being an area associated with the printer in which the substrate media is marked with an image; a hold-down system operative to generate a hold-down pressure applied to the substrate media in the direction of the first media transport; a precurler unit operative to apply a predetermined degree of curl to the substrate media; a media height sensor operative to determine the height of the substrate media above the first media transport under the influence of the hold-down pressure; a print head array operative to mark the substrate media with an image in the marking zone; an actuator operative to adjust the relative spacing between the print head array and the first media transport between a first relative spacing at which marking of the substrate media may selectively occur and a second relative spacing greater than the first spacing at which no marking occurs; and a controller configured and operative to direct the substrate media into the marking zone with the actuator set at the second relative spacing prior to directing substrate media through the print zone with the actuator set at the first relative spacing for marking.
