Title:
ELEMENT SUBSTRATE, LIQUID DISCHARGE HEAD, AND RECORDING DEVICE
Document Type and Number:
Japanese Patent JP2019001172
Kind Code:
A
Abstract:
To provide a discharge state determination method of liquid discharged from a liquid discharge head which can execute determination of an ink discharge state of each nozzle accurately and at high speed, with a simple configuration.SOLUTION: A substrate 108 includes: an electro-thermal conversion element 104 for supplying heat to ink; a first temperature detection element 105A for detecting temperature of the electro-thermal conversion element 104; and a second temperature detection element 105B for detecting temperature of the same electro-thermal conversion element 104. In this case, immediately above or immediately below a region in which the electro-thermal conversion element 104 is arranged on the substrate 108, the first temperature detection element 105A and the second temperature detection element 105B are arranged so that at least one part of each of the elements is included.SELECTED DRAWING: Figure 6
