摘要： After the control section of a printer (liquid discharge apparatus) discharges ink on the basis of a print job, the control section waits for an input of the next print job while causing the discharge section to perform flushing. If the next print job is input before the elapsed time Te from the end of the ink discharge on the basis of the print job exceeds the waiting time Tw, the control section causes ink to be discharged on the basis of the next print job. On the other hand, if the next print job is not input before the elapsed time Te exceeds the waiting time Tw, the control section causes the cap to be subjected to capping.

摘要： A liquid ejection device includes a transport unit, a medium support unit and a liquid ejection head. The medium support unit includes a plurality of first recesses and a plurality of second recesses arranged on a medium support surface along a width direction orthogonal to a transport direction. The first and second recesses are configured and arranged to be imparted with negative pressure. A width dimension of an opening of the first recess in the width direction is larger on the downstream side than on an upstream side. A width dimension of an opening of the second recess in the width direction is smaller than the width dimension of the opening of the first recess in the width direction on the downstream side with respect to the transport direction. The second recesses are configured and arranged to accept the liquid ejected toward the ejection medium from the liquid ejection head.
