Abstract
The ink-jet recording device of the present invention is provided with an ink-jet recording head that operates pressure waves on ink in a pressure chamber and ejects ink droplets from multiple nozzles; a wiper that wipes a nozzle face of the ink-jet recording head; a drive waveform applying component that applies a drive waveform to a drive element so that ink droplets are not ejected and ink floods the nozzle face; and a control component that, when performing wiping, drives the drive waveform applying component prior to initiating wiping and actuates the wiper in a state where the ink is flooded on the nozzle face.
Claims14
An ink-jet recording device comprising:
- an ink-jet recording head that operates pressure waves on ink in a pressure chamber and ejects ink droplets from a plurality of nozzles;
- a wiper that wipes a nozzle face of the ink-jet recording head;
- a drive waveform applying component that applies a drive waveform to a drive element such that ink droplets are not ejected and ink floods the nozzle face;
- and
- a control component that, when wiping is being performed, drives the drive waveform applying component prior to the initiation of wiping and actuates the wiper when the ink is in a flooded condition on the nozzle face;
- wherein the drive waveform is a triangular waveform.
A wiping method that wipes a nozzle face of an ink-jet recording head without performing suction of ink, the method comprising:
- applying a drive waveform to a drive element so that, prior to initiating wiping, ink droplets are not ejected and ink floods the nozzle face;
- and
- wiping the nozzle face in a state where ink is flooded on the nozzle face;
- wherein the drive waveform is a triangular waveform.
