Abstract
According to an example, a printing system may include a drop ejecting element and a fluid circulating element corresponding to the drop ejecting element. The printing system may also include a logic device that is to receive a data stream addressed to the drop ejecting element, determine whether the data stream indicates that the drop ejecting element is to be energized, and in response to a determination that the data stream does not indicate that the drop ejecting element is to be energized, energize the fluid circulating element.
Claims15
A printing system comprising:
- a fluid ejection chamber having a nozzle;
- a drop ejecting element positioned in the fluid ejection chamber to cause a droplet of fluid in the fluid ejection chamber to be ejected through the nozzle;
- a fluid circulation channel in communication with the fluid ejection chamber and a fluid feed slot;
- a fluid circulating element positioned in the fluid circulation channel to circulate fluid through the fluid circulation channel and the fluid ejection chamber;
- a logic device to:
- receive a data stream addressed to the drop ejecting element;
- determine whether the data stream indicates that the drop ejecting element is to be energized;
- and
- in response to a determination that the data stream does not indicate that the drop ejecting element is to be energized, energize the fluid circulating element.
A method comprising:
- receiving, by a logic device, a data stream addressed to a drop ejecting element of a fluid ejection device, said fluid ejection device having a fluid circulating element in fluid communication with a fluid ejection chamber housing the drop ejecting element, wherein the drop ejecting element and the fluid circulating element are independently addressable;
- determining, by the logic device, whether the data stream indicates that the drop ejecting element is to be energized;
- and
- in response to a determination that the data stream does not indicate that the drop ejecting element is to be energized, energizing, by the logic device, the fluid circulating element.
A non-transitory computer readable storage medium on which is stored machine readable instructions that when executed by a processor are to cause the processor to:
- receive a data stream addressed to a drop ejecting element of a fluid ejection device, said fluid ejection device having a fluid circulating element in fluid communication with a fluid ejection chamber housing the drop ejecting element, wherein the drop ejecting element and the fluid circulating element are independently addressable;
- determine whether the data stream indicates that the drop ejecting element is to be energized;
- and
- in response to a determination that the data stream does not indicate that the drop ejecting element is to be energized, energize the fluid circulating element.
