Abstract
A liquid ejecting apparatus includes a switch which performs switching between a platen applied voltage generation section side and the ground side with respect to a platen which supports a recording medium, wherein in a case where recording paper is present on the platen, the switch is switched to the ground side, so that the platen is set to have the same potential as that of a nozzle formation face, and on the other hand, in a case where the recording paper is not present on the platen, the switch is switched to the platen applied voltage generation section side, so that the platen is electrically charged to have negative polarity.
Claims5
A liquid ejecting apparatus comprising:
- a liquid ejecting head which includes a nozzle formation face, and ejects the liquid from the nozzle toward a landing target;
- a support section which is disposed spaced apart from the nozzle formation face of the liquid ejecting head when performing an ejection operation and supports the landing target;
- a support section potential setting section which sets the potential of the support section to be the same potential as that of the nozzle formation face;
- and
- a voltage application section which applies voltage having negative polarity to the support section,
- wherein in a case where the landing target is present on the support section, the support section is set to have the same potential as that of the nozzle formation face by the support section potential setting section, and on the other hand, in a case where the landing target is not present on the support section, the support section is electrically charged to have negative polarity by the voltage application section.
