Abstract
In some examples, a fluid-ejection device can include a fluidic tube to fluidically connect to a fluid supply, a carriage having a fluidic interconnector fluidically connectable to the fluidic tube and movable between a first position and a second position, a receiver to receive an air purger, wherein the air purger, when present, is coupled to the receiver and fluidically connectable to the fluidic interconnector, and a controller to cause the carriage to actuate from the first position to the second position, determine a location of the carriage at the second position, and based on the location of the carriage at the second position, detect a status of the air purger, a status of an engageable lock in the air purger, or both.
Claims15
A fluid-ejection device comprising:
- a fluidic tube to fluidically connect to a fluid supply;
- a carriage having a fluidic interconnector fluidically connectable to the fluidic tube and movable between a first position and a second position;
- a receiver to receive an air purger, wherein the air purger, when present, is coupled to the receiver and fluidically connectable to the fluidic interconnector;
- and
- a controller to:
- cause the carriage to actuate from the first position to the second position;
- determine a location of the carriage at the second position;
- and
- based on the location of the carriage at the second position, detect:
- a status of the air purger, a status of an engageable lock in the air purger, or both.
A system comprising:
- an air purger;
- and
- a fluid-ejection device comprising:
- a fluidic tube to fluidically connect to a fluid supply;
- a carriage having a fluidic interconnector fluidically connectable to the fluidic tube and movable between a first position and a second position;
- a receiver to receive the air purger, wherein the air purger is coupled to the receiver and fluidically connectable to the fluidic interconnector;
- and
- a controller to:
- cause the carriage to actuate from the first position to the second position;
- determine a distance between the first position and the second position;
- compare the distance to a threshold;
- and
- based on the comparison of the distance to the threshold, detect a status of the air purger, a status of an engageable lock, or both.
A controller comprising:
- a processing resource;
- and
- a memory resource storing non-transitory machine-readable instructions to cause the processing resource to:
- cause a carriage in a fluid-ejection device having a continuous ink supply system (CISS) to actuate from a first position to a second position;
- determine a distance between the first position and the second position;
- compare the distance to a threshold;
- based on the comparison of the distance to the threshold, determine a status of an air purger included in the fluid-ejection device, a status of an engageable lock, or both;
- and
- based on the status of the air purger and the status of the engageable lock cause the air purger or a back-up purge system to purge air from the fluid-ejection device.
