Abstract:
1. A system for reducing electrostatic fields underneath print heads, the system comprising: one or more print heads for depositing ink onto a surface of a media substrate in one or more ink deposition areas; a media transport for moving the media substrate along a media path in a process direction past the one or more print heads, wherein the media transport comprises a media transport belt having a first side and a second side, and wherein the media substrate has an electrostatic field and contacts the first side; a conductive platen contacting the media transport belt on the second side, wherein the conductive platen has one or more apertures; one or more electrically isolated biased electrodes positioned in the one or more apertures and corresponding to the locations of the one or more ink deposition areas of the one or more print heads, and wherein each of the one or more electrically isolated biased electrodes extends in the process direction and in a trans-process direction; and one or more voltage sources for providing a voltage to the one or more electrically biased electrodes, wherein the voltage is provided to the one or more electrically biased electrodes to reduce the electrostatic field on the surface of the media receiving the ink.
