ABSTRACT:
An inkjet printer includes a recording head ejecting ink from a nozzle plate surface, a plurality of wipers moving in a predetermined movement direction with respect to the recording head for wiping the liquid from the nozzle plate surface, and a movement device for moving the wipers in the movement direction. The movement device moves the wipers at variable intervals in the movement direction, so that the wipers can wipe the nozzle plate surface independently from one another.
