  • Publication number: 20100231640
    Abstract: A liquid ejecting apparatus includes a liquid ejecting head that performs liquid ejection with respect to an ejection target medium, a carriage that reciprocates with the liquid ejecting head being mounted, a linear encoder that has a linear encoder scale extending in a movement direction of the carriage and a detector which detects the linear encoder scale, a cleaning member that cleans the linear encoder scale, and a recovery unit that recovers the liquid adhered to the cleaning member in a non-ejection area other than an ejection area for performing ejection with respect to the ejection target medium.
