Claims23
A method of controlling a capacitive mat, the method comprising:
- energizing first and second nodes of the capacitive mat with opposite polarity;
- loading first media onto the capacitive mat;
- positioning the first media in a print zone;
- forming an image on the first media;
- reversing the polarity of the first and second nodes;
- and
- removing the first media from the print zone before the reversing the polarity of the first and second nodes.
A method of controlling a capacitive mat, the method comprising:
- energizing first and second nodes of the capacitive mat with opposite polarity;
- loading first media onto the capacitive mat;
- positioning the first media in a print zone;
- forming image on the first media;
- reversing the polarity of the first and second nodes;
- maintaining the polarities of the first and second nodes while the first media is disposed within the print zone.
A media handling apparatus, comprising:
- a platen having first and second conductor arranged such that individual first conductor are separated by at least one individual second conductor;
- a polarity control device configured to energize the first and second conductors with opposite polarity and to reverse the polarity of the first and second conductors according to a detected location of a sheet of print medium.
An image forming device, comprising:
- a print engine;
- platen disposed adjacent the print engine, the platen having first and second electrodes;
- circuitry configured to charge the first and second electrodes with opposite polarity and to reverse the polarity of the first and second electrodes based on media location.
A device comprising:
- a print engine for forming an image on media positioned in a print zone;
- means for energizing first and second nodes of a capacitive mat with opposite polarity and reversing the polarity of the first and second nodes no more than five (5) seconds before loading media on the capacitive mat.
A method for controlling a capacitive mat, the method comprising:
- energizing first and second nodes of the capacitive mat with opposite polarity;
- forming an image on media positioned in a print zone;
- reversing the polarity of the first and second nodes no more than five (5) seconds before loading media on the capacitive mat.
A method for controlling a capacitive mat, the method comprising:
- energizing first and second nodes of the capacitive mat with opposite polarity;
- forming an image on media positioned in a print zone;
- reversing the polarity the first and second nodes returning the media to the print zone after the reversing tire polarity of the first and second nodes.
A method for controlling a capacitive mat, the method comprising:
- energizing first and second nodes of the capacitive mat with opposite polarity;
- loading first media onto the capacitive mat;
- positioning the first media in a print zone;
- forming a first image on the first media;
- advancing the first media from the print zone;
- reversing the polarity of the first and second nodes;
- removing the first media from the capacitive mat before the reversing the polarity of the first and second nodes;
- loading second media onto the capacitive mat after the reversing of the polarity of the first and second nodes within five (5) seconds of the reversing the polarity of the first and second nodes.
