Abstract
According to the present invention, firstly, since the cleaning liquid is deposited onto the nozzle surface by the nozzle surface cleaning liquid deposition device, then it is possible to raise the dissolving effect, which is a chemical effect of dissolving adhering material which is adhering to the nozzle surface. Consequently, it is possible to remove the adhering material readily by subsequently wiping the nozzle surface with the wiping member, and hence the physical effects can also be improved. Furthermore, since the cleaning liquid is deposited so as to wet the wiping member, then it is possible to suppress the drawing out of liquid from the nozzles due to the absorbing characteristics of the wiping member, and therefore ejection defects due to solidification of drawn out liquid can be prevented. Consequently, it is possible to improve ejection stability of the droplet ejection head.
