Abstract
Techniques related to printing using a metal-surface charge element. A metal-surface charge element includes at least one metal charge roller to deposit electric charge on an imaging surface. Each metal charge roller includes a metal external surface in charge-transferring relation with the imaging surface and in a glow discharge regime during operation of the printing system for printing.
Claims20
A printing system comprising a metal-surface charge element that includes at least one metal charge roller to deposit electric charge on an imaging surface, each metal charge roller including a metal external surface in charge-transferring relation with the imaging surface and in a glow discharge regime during operation of the printing system for printing.
A method of operating a printer with a metal-surface charge element, the method comprising:
- electrically charging an imaging surface of the printer by applying electric charge in a glow discharge regime to a metal-surface charge element that includes at least one metal charge roller, each metal charge roller in rotational and charge-transferring relation with the imaging surface;
- forming a charge image on the electrically-charged imaging surface;
- applying ink to the imaging surface to image the ink according to the charge image;
- and
- transferring the imaged ink to paper.
A method of manufacturing a printing system, the method comprising:
- disposing a metal-surface charge element that includes at least one metal charge roller adjacent an imaging surface with each metal charge roller in rotational and charge-depositing relation with the imaging surface;
- and
- providing a power supply to charge each metal charge roller to a potential within a glow discharge regime.
A metal-surface charge element for a liquid electrophotographic printer, the metal-surface charge element comprising at least one metal charge roller to deposit electric charge on an imagine surface, the metal charge roller in charge-transferring relation with the imaging surface and in a glow discharge regime during operation of the printing system for printing.
