Abstract
In one example in accordance with the present disclosure, an interconnect on a print liquid supply is described. The interconnect includes a liquid interface to establish a liquid path between the print liquid supply and an ejection device in which the print liquid supply is installed. The interconnect also includes an electrical interface to establish a data transmission path between the print liquid supply and the ejection device. The interconnect also includes an external surface having a dampening element disposed thereon.
Claims20
An interconnect on a print liquid supply comprising:
- a liquid interface to establish a liquid path between the print liquid supply and an ejection device in which the print liquid supply is installed;
- an electrical interface to establish a data transmission path between the print liquid supply and the ejection device;
- and
- an external surface of the interconnect having a dampening element disposed thereon, the dampening element to counter an ejection force of the print liquid supply.
An interconnect on an ejection device comprising:
- a needle to be inserted into a print liquid supply to allow print liquid from the print liquid supply to pass to the ejection device;
- an electrical interface to establish a data transmission path between the print liquid supply and the ejection device;
- and
- a rotary motion damper to dampen, via a controlled counter-rotation, a tangential spring-based ejection force.
A printing system comprising:
- a printer comprising:
- an ejection device to deposit print liquid onto a substrate;
- a controller to control operation of the ejection device to deposit the print liquid in a desired pattern;
- and
- an interconnect comprising:
- a needle to be inserted into a print liquid supply to allow print liquid from the print liquid supply to pass to the ejection device;
- an electrical interface to establish a data transmission path between the print liquid supply and the ejection device;
- and
- a rotary motion damper to dampen, via a controlled counter-rotation, a tangential spring-based ejection force;
- and
- a print liquid supply comprising:
- a reservoir to hold the print liquid;
- and
- an interconnect on a print liquid supply comprising:
- a liquid interface to establish a liquid path between the print liquid supply and an ejection device in which the print liquid supply is installed;
- an electrical interface to establish a data transmission path between the print liquid supply and the ejection device;
- and
- a number of slots formed on an external surface of the interconnect;
- wherein the slots and the rotary motion damper form a rack and pinion.
