Title:
液体吐出ヘッドのクリーニング方法、液体吐出装置
Document Type and Number:
Japanese Patent JP6833410
Kind Code:
B2
Abstract:
A method of cleaning a liquid discharge head, which includes a heat generating resistor that generates thermal energy for discharging a liquid and a covering portion covering the heat generating resistor, includes alternately performing a first voltage application process and a second voltage application process multiple times, and reducing energy applied in the second voltage application process. The first voltage application process includes applying voltage between the covering portion and an electrode through the liquid to dissolve the covering portion in the liquid. The second voltage application process includes reversing relative polarities of the covering portion and the electrode in the first voltage application process and applying voltage between the covering portion and the electrode. Energy applied in the second voltage application process is reduced such that the energy applied is less than energy applied in the first voltage application process of an immediately preceding time.
