Abstract
A liquid discharging apparatus includes: a first drive circuit outputting a first drive signal based on the second base drive signal; and a first discharging head including a first discharging portion and a first switching circuit, in which when the state information signal does not include information indicating an abnormality in a state, the second control circuit outputs the second discharge control signal based on the first discharge control signal, and when the state information signal includes the information indicating an abnormality in the state, the second control circuit outputs the second discharge control signal for controlling the first switching circuit not to supply the first drive signal to the first discharging portion.
Claims9
A liquid discharging apparatus that discharges liquid on a medium comprising:
- a first control circuit outputting a first discharge control signal, a first base drive signal, and a transport control signal for controlling transport of the medium;
- a second control circuit receiving the first discharge control signal, the first base drive signal, and a state information signal indicating a state of the liquid discharging apparatus, and outputting a second discharge control signal and a second base drive signal;
- a first drive circuit outputting a first drive signal based on the second base drive signal;
- a first substrate provided with the first control circuit;
- a second substrate provided with the second control circuit and the first drive circuit;
- and
- a first discharging head including a first discharging portion that discharges liquid in response to the first drive signal and a first switching circuit that switches whether or not to supply the first drive signal to the first discharging portion based on the second discharge control signal, wherein
- when the state information signal does not include information indicating an abnormality in the state, the second control circuit outputs the second discharge control signal based on the first discharge control signal, and
- when the state information signal includes the information indicating an abnormality in the state, the second control circuit outputs the second discharge control signal for controlling the first switching circuit not to supply the first drive signal to the first discharging portion.
