Abstract
A liquid electrophotography (LEP) printing device includes a binary ink developer (BID) assembly to receive ink from an ink supply. The BID assembly including a developer electrode, a developer roller, and a squeegee roller. The LEP printing device includes a photoconductive imaging cylinder to which the BID assembly is to transfer the ink in accordance with an electrostatic image on the imaging cylinder. The LEP printing device includes one or multiple power supplies to provide power to either or both of the developer electrode and the squeegee roller in a constant current mode.
Claims15
A liquid electrophotography (LEP) printing device comprising:
- a binary ink developer (BID) assembly to receive ink from an ink supply, the BID assembly including a developer electrode, a developer roller, and a squeegee roller;
- a photoconductive imaging cylinder to which the BID assembly is to transfer the ink in accordance with an electrostatic image on the imaging cylinder;
- and
- one or multiple power supplies to provide power to either or both of the developer electrode and the squeegee roller in a constant current mode.
A power supply for a binary ink developer (BID) assembly of a liquid electrophotography (LEP) printing device, comprising:
- a switching circuit to provide power to a developer electrode or a squeegee roller of the BID assembly of the LEP printing device;
- and
- a control circuit to maintain providing of the power by the switching circuit to the developer electrode or the squeegee roller in a constant current mode.
A method comprising:
- providing power from one or multiple power supplies to either or both of a developer electrode of a binary ink developer (BID) assembly of a liquid electrophotography (LEP) printing device and a squeegee roller of the BID assembly in a constant current mode.
