Claim Text:
1. A liquid dispensing device, comprising: a controller to control dispensing of a first drop from a first orifice and a second drop from a second orifice; a sensor to monitor the first orifice to detect at least one of a presence or an absence of a drop from the first orifice and to monitor the second orifice to detect at least one of a presence or an absence of a drop from the second orifice; in response to the sensor detecting an absence of the first drop, the controller to classify the first orifice as at least one of occluded or non-functioning; in response to the sensor detecting a presence of the second drop, the controller to classify the second orifice as functional; when the first orifice is classified as at least one of occluded or non-functioning, the second orifice is classified as functional, and the first orifice was dispensing a first fluid solution prior to being classified as the at least one of occluded or non-functioning, the controller to cause the second orifice to dispense drops of the first fluid solution toward a drop receiving well until a tally of drops received within the drop receiving well satisfies a first threshold; and when the first orifice is classified as the at least one of occluded or non-functioning, the second orifice is classified as functional, and the first orifice was dispensing a second fluid solution prior to being classified as the at least one of occluded or non-functioning, the controller to cause the second orifice to dispense drops of the second fluid solution toward the drop receiving well until a tally of drops received within the drop receiving well satisfies a second threshold, the first fluid solution being different from the second fluid solution, the first threshold being different from the second threshold.
