Abstract
A recording device, when recording is performed on a predetermined type target recording medium stored in a storage unit, drives a surface potential adjustment unit so that a surface potential is a positive potential within a predetermined range. By configuring such a recording device, it is possible to suppress adhesion of ink to an ejecting unit, and occurrence of an ink ejection failure can be suppressed.
Claims9
A recording device, comprising:
- a transport unit configured to transport a target recording medium;
- a corona irradiation unit disposed in a transport path of the target recording medium, and configured to apply corona discharge to a surface of the target recording medium to modify the surface;
- an ejecting unit disposed downstream of the corona irradiation unit in the transport path, and configured to eject an ultraviolet curable ink onto the surface;
- a surface potential adjustment unit disposed between the corona irradiation unit and the ejecting unit in the transport path, and configured to adjust a surface potential being a potential of the surface;
- a control unit configured to control driving of the transport unit, the corona irradiation unit, the ejecting unit, and the surface potential adjustment unit;
- and
- a storage unit configured to store a predetermined type target recording medium being a predetermined type of the target recording medium, wherein
- the control unit, when recording is performed on the predetermined type target recording medium stored in the storage unit, controls driving of the surface potential adjustment unit such that the surface potential is a positive potential within a predetermined range.
