Abstract
A fluid ejection device incudes a reservoir to contain a cell solution and a fluid ejection die having an ejector to dispense a cell of the cell solution from the reservoir into a well of a well plate, a channel connecting the reservoir and the ejector, a sense area within the channel, and a clog clearing device proximate the sense area to clear a clog sensed in the sense area.
Claims20
A fluid ejection device, comprising:
- a reservoir to contain a cell solution;
- and
- a fluid ejection die comprising:
- an ejector to dispense a cell of the cell solution from the reservoir onto a substrate;
- a channel connecting the reservoir and the ejector;
- a sense area within the channel;
- and
- a clog clearing device proximate the sense area to clear a clog sensed in the sense area.
5 more elements
A method comprising:
- measuring, using a sensing circuit in a sense area within a channel connecting a reservoir to an ejector, an impedance as a cell of a cell solution travels through the channel from the reservoir to the ejector for dispensing onto a substrate;
- comparing the impedance that is measured to a threshold impedance value;
- detecting a clog proximate the sense area in response to determining that the impedance that is measured is greater than the threshold impedance value;
- and
- activating a clog clearing device proximate the sense area to disperse the clog.
