Abstract

A liquid ejection apparatus including: a head having an ejection face and configured to eject liquid toward a recording medium; a capping mechanism which switches the ejection space being opposite the ejection face between capped and uncapped states; a conveyor which conveys the recording medium along a conveyance path; a sensor which senses whether the recording medium is present at a sensing position located on an upstream portion of the conveyance path; and a controller configured to: control the capping mechanism and the conveyor; determine whether the conveyor is normal, based on driving of the conveyor for a first period from the start of the driving of the conveyor in the capped state; and when the recording medium is sensed by the sensor within the first period, stop the driving of the conveyor even before the first period passes from the start of the driving of the conveyor.

First claim

What is claimed is:

1. A liquid ejection apparatus comprising:
a liquid ejection head comprising an ejection face in which a plurality of ejection openings are formed, the liquid ejection head being configured to eject liquid toward a recording medium through the plurality of ejection openings, an ejection space being opposite the ejection face;
a capping mechanism configured to switch a state of the ejection space between a capped state in which the ejection space is substantia…
