METHOD OF RESTORING INKJET RECORDING HEAD AND INKJET RECORDER

摘要

PROBLEM TO BE SOLVED: To provide an operation of restoring in an inkjet recording head capable of efficiently peeling a scorched material in the inkjet recording head for ejecting ink by utilizing bubble jetting energy by virtue of heating of a heating element even when an ink easily causing a scorch is used. SOLUTION: After preliminary ejection by a pulse having a comparatively low energy intensity is carried out, preliminary ejection by a pulse having a comparatively high energy intensity is carried out. A new scorch 1302 caused by the pulse having the low energy intensity provided on the scorch 1301 to be peeled raises an effect of peeling the scorch caused by the pulse having the high energy intensity.
