    摘要: A media transport apparatus includes a first media transport, having a first transport surface and a first drive unit, to convey the substrate media. A second media transport having a second transport surface and a second drive unit receives the substrate media from the first. A first force transducer outputs a force signal associated with a first force between the media transports. A control unit receives the force signal, and outputs a control signal to at least one of the first and second drive units that is dependent upon a comparison of the first relative force signal with a predetermined value. The control signal commands the first or second drive unit to drive the motion of the respective first or second media transport to maintain the force signal at or about no greater than the predetermined value.

    摘要: A system and method for adjusting an electrostatic field in a print zone of an inkjet printer. The printer includes an electrostatic tacking device to hold a sheet of recording media to a transport belt moving through the print zone for imaging with one or more inkjet printheads. A sensor determines the electrostatic field before the print zone and adjusts the electrostatic field with a corotron disposed after the tacking device and before the print zone. Reduction of the electrostatic field in the print zone can reduce imaging errors resulting from electrostatic fields.
