Abstract:
1. A method of adjusting an electrostatic field in a print zone of an inkjet printer to reduce the effects of the electrostatic field during the deposition of ink on recording media moving though the print zone in a process direction comprising: applying a charge with a corotron to the recording media on a transport belt prior to the recording media moving through the print zone to affix the recording media to the transport belt, which is configured to transport media in a process direction past a printhead in the print zone; measuring with a sensor disposed adjacent to the transport belt an electrostatic field on the transport belt at a location prior to the recording media entering the print zone, the sensor generating a signal indicative of a strength of the electrostatic field on the transport belt; and modifying the charge on the recording media in the print zone in response the signal generated by the sensor, the charge being modified with a controller operatively connected to the corotron and the sensor.
