Abstract
Example implementations provide a method of controlling an ink developer used in electro-photography; the method comprising, following cessation of printing, varying a plurality of voltages associated with movement of ink within the ink developer at temporally disparate times.
Claims13
A printer for printing to a substrate;
- the printer comprising an ink developer;
- the ink developer comprising a plurality of members operable in response to a plurality of voltages to influence forming an image;
- the printer comprising circuitry, responsive to cessation of printing, to vary at least one voltage of the plurality of voltages in a temporally offset manner relative to at least one other voltage of the plurality of voltages to influence ink movement associated with at least one member of said plurality of members, wherein the plurality of members comprises an electrode and said circuitry to vary at least one voltage comprises circuitry to vary an electrode voltage of the electrode by reducing the potential difference between the electrode voltage and at least one voltage of the plurality of voltages.
A controller for a printing device for printing to a medium;
- the printing device comprising at least one ink developer;
- the ink developer comprising a developer roller, responsive to respective developer roller voltage;
- the controller comprising circuitry to manage at least one other voltage associated with at least one further member of the ink developer relative to the developer roller voltage to influence movement of ink within the ink developer, wherein said at least one member comprises a squeegee roller, having a respective squeegee roller voltage.
Non-transitory machine readable storage storing machine executable code arranged, when executed by at least one processor, to sequentially reduce potential differences between a developer roller voltage of a developer roller of an ink developer and at least one other voltage associated with the ink developer in a staggered manner.
