Abstract:
1. An inkjet printing apparatus, comprising: a media transport unit to transport a print media along a print media transport path in a print media transport direction; at least one inkjet printhead assembly including an inkjet printhead having a plurality of nozzles to print on a select portion of the print media, the inkjet printhead forming a print region adjacent to the nozzles in an area between the printhead assembly and a print portion of the print media transport path; at least one of an electrostatic discharge unit to neutralize a resulting electrical charge on at least the select portion of the print media before the at least select portion of the print media enters the print region and a neutralization unit to neutralize an electric field in the print region; a measurement unit disposed proximate to the at least select portion of the print media, and to measure the resulting electrical charge or voltage of the at least select portion of the print media; and a control unit to control at least one of the electrostatic discharge unit and the media transport unit based on the measured resulting electrical charge or voltage provided from the measurement unit.
