Abstract
An example method of controlling a printing process in accordance with aspects of the present disclosure includes controlling an optical density of a printed image such that the optical density is increased for a predetermined portion of a leading edge of a page.
Claims14
A method of controlling a printing process, the method comprising:
- increasing an optical density of a printed image for a predetermined portion of a leading edge of a page, including increasing a voltage applied to a developer roller of a printing device from a default developer voltage to an increased developer voltage higher than the default developer voltage, during the predetermined portion of the leading edge of the page;
- and
- after the predetermined portion of the leading edge of the page, returning the voltage applied to the developer roller to the default developer voltage.
A controller for controlling a printing process of a printing device, the controller comprising:
- a processor to:
- increase an optical density of a printed image for a predetermined portion of a leading edge of a page, by increasing a voltage applied to a developer roller of the printing device from a default developer voltage to an increased developer voltage higher than the default developer voltage, during the predetermined portion of the leading edge of the page;
- and
- after the predetermined portion of the leading edge of the page, return the voltage applied to the developer roller to the default developer voltage.
1 more element
A non-transitory computer readable medium storing instructions that when executed by a processor cause the processor to:
- increase an optical density of a printed image for a predetermined portion of a leading edge of a page, by increasing a voltage applied to a developer roller of a printing device from a default developer voltage to an increased developer voltage higher than the default developer voltage, during the predetermined portion of the leading edge of the page;
- and
- after the predetermined portion of the leading edge of the page, return the voltage applied to the developer roller to the default developer voltage.
