Abstract
There is provided a liquid discharge system that controls an operation of a liquid discharge head provided with a first nozzle for discharging a liquid, the liquid discharge system including: an acquisition section that acquires first information indicating a discharge state of the first nozzle; a reception section that receives second information on a determination reference for determining that the discharge state of the first nozzle is abnormal according to an operation of a user; and a determination section that determines presence or absence of a discharge abnormality of the first nozzle based on the first information and the second information.
Claims13
A liquid discharge system that controls an operation of a liquid discharge head provided with a first nozzle for discharging a liquid, the liquid discharge system comprising:
- an acquisition section configured to acquire an estimated viscosity of liquid within the first nozzle of the liquid discharge head;
- a reception section configured to receive a determination reference for adjusting a viscosity threshold value for determining that the discharge state of the first nozzle is abnormal, the determination reference provided in response to user input;
- and
- a determination section configured to determine presence or absence of a discharge abnormality by determining that the discharge state of the first nozzle is abnormal if the estimated viscosity of the liquid within the first nozzle is above the viscosity threshold value as adjusted according to the determination reference, and by determining that the discharge state of the first nozzle is normal when the estimated viscosity is lower than the viscosity threshold value as adjusted according to the determination reference.
A method for a liquid discharge system to determine a discharge state of a first nozzle, the method comprising:
- acquiring, by an acquisition section, an estimated viscosity of liquid within the first nozzle of the liquid discharge head;
- receiving, by a reception section, a determination reference for adjusting a viscosity threshold value for determining that the discharge state of the first nozzle is abnormal, the determination reference provided in response to user input;
- and
- determining, by a determination section, that there is a discharge abnormality in the first nozzle by determining that the estimated viscosity of the liquid within the first nozzle is above the viscosity threshold value as adjusted according to the determination reference.
