Patent JP-2022131463-A (JP)
Title: Liquid discharge device
Inventor: NAKASE TAKAFUMI
IPC: B41J2/01
Filed: 2021-02-26
Abstract: To more accurately determine whether or not a nozzle is an abnormal nozzle.SOLUTION: A determination signal for determining whether or not a nozzle is an abnormal nozzle is output from a signal processing circuit. When ink is normally discharged from the nozzle, the determination signal is assumed to be maximum at a first timing U1 and be minimum at a timing U2 later the first timing U1 in a determination period T. When a difference (Va-Vb) between a maximum value Va in a first continuous period T1 including the first timing U1 and a minimum value Vb in a second continuous period T2 including the second timing U2 but not including the first timing is equal to or more than a threshold Vt, the determination signal determines that the nozzle is not the abnormal nozzle, and when the difference is less than the threshold Vt, the determination signal determines that the nozzle is the abnormal nozzle.SELECTED DRAWING: Figure 3
