Abstract
A pair of ink jet print heads are arranged on opposite sides of a conveyor to apply ink markings to the opposed surfaces of material conveyed on the conveyor. The print heads support ink jet nozzle blocks having at least one ink jet nozzle and are pivotally biased out over the conveyor in the path of the conveyed material. A pair of cams positioned on opposite sides of the ink jet nozzle blocks maintain a critical spacing between the nozzle block and the surface of the material. Ramp surfaces and an exit cam control the rate at which the ink jet print heads are pivoted away from and toward the path of the conveyed material as the material is conveyed before the ink jet print heads.
