Publication number: 20160288536Abstract: Provided is an air jet emission method used in a recording apparatus. The recording apparatus performs predetermined printing by ejecting ink droplets from a recording head provided in an apparatus body onto a medium. The medium is fed into the apparatus body while being guided by a guide and is transported from an upstream side, which is one side with respect to the apparatus body, toward a downstream side, which is an opposite side with respect to the apparatus body. The air jet emission method comprises: emitting a jet of air onto a surface of the transported medium at a predetermined area over a heating device at the upstream side, thereby blowing dust off the surface of the transported medium. The heating device is provided in the guide so as to apply heat to the transported medium.Type: ApplicationFiled: March 23, 2016Publication date: October 6, 2016Inventors: Shigeki SUZUKI, Toshinobu YAMAZAKI, Masahiko SATO
