Abstract

A liquid ejecting device includes a first liquid ejecting unit configured to eject recording liquid onto a medium, a second liquid ejecting unit configured to eject disinfectant liquid onto the medium, and a control unit configured to control the first liquid ejecting unit and the second liquid ejecting unit, wherein the control unit is configured to cause the disinfectant liquid to eject avoiding a position at which the recording liquid ejects on the medium.

First claim

What is claimed is:

1. A liquid ejecting device comprising:
a first liquid ejecting unit configured to eject recording liquid onto a medium;
a second liquid ejecting unit configured to eject disinfectant liquid onto the medium; and
a control unit configured to control the first liquid ejecting unit and the second liquid ejecting unit, wherein
the control unit is configured to cause the disinfectant liquid to eject on the medium avoiding a position at which the recording liquid ejects.

2. The liquid ejecting device according to claim 1 , wherein
the control unit is configured to cause the disinfectant liquid to eject at margins along edges on four sides of the medium.

3. The liquid ejecting device according to claim 1 , wherein
the second liquid ejecting unit is disposed downstream of the first liquid ejecting unit in a transport direction of the medium.

4. The liquid ejecting device according to claim 1 , comprising a head unit that includes the first liquid ejecting unit and the second liquid ejecting unit and configured to move in a width direction that is a direction intersecting the transport direction of the medium, wherein
provided that a first direction is a moving direction in which the head unit moves, the second liquid ejecting unit is positioned in a second direction opposite to the first direction with respect to the first liquid ejecting unit.

5. The liquid ejecting device according to claim 1 , wherein
the first liquid ejecting unit and the second liquid ejecting unit are provided in an identical liquid ejecting head.

6. The liquid ejecting device according to claim 1 , comprising a medium inversion path configured to invert the medium after a first surface of the medium passes through a position facing the first liquid ejecting unit and a position facing the second liquid ejecting unit such that a second surface opposite to the first surface faces the first liquid ejecting unit and the second liquid ejecting unit, wherein
the control unit is configured to adjust a volume of the disinfectant liquid ejected from the second liquid ejecting unit to reduce a difference between a total volume of liquid ejected onto the first surface and a total volume of liquid ejected onto the second surface.

7. The liquid ejecting device according to claim 1 , comprising:
a transporting belt configured to transport the medium, the transporting belt being provided at a position facing the first liquid ejecting unit; and
a cleaning sheet configured to contact and clean the transporting belt, wherein
the control unit includes a cleaning mode in which cleaning of the transporting belt is performed by the cleaning sheet after the disinfectant liquid is ejected from the second liquid ejecting unit onto the transporting belt.

8. A liquid ejecting system comprising:
the liquid ejecting device according to claim 1 ; and
a drying section configured to perform drying processing on the medium, the drying section being provided downstream of the first liquid ejecting unit and the second liquid ejecting unit in the transport path of the medium.

9. A liquid ejecting method for a liquid ejecting device, the liquid ejecting device comprising:
a first liquid ejecting unit configured to eject recording liquid onto a medium; and
a second liquid ejecting unit configured to eject disinfectant liquid onto the medium, wherein
the method comprising:
causing the disinfectant liquid to eject on the medium avoiding a position at which the recording liquid ejects.
