Abstract
The recording apparatus includes a conveyor and a recording head which records an image to a recording medium being conveyed by the conveyor. The conveyor includes a circumferential wall, and conveys a recording medium placed on an outer circumferential surface of the circumferential wall, by rotation of the circumferential wall. The recording head includes an ejection surface where a plurality of nozzles are open, which nozzles eject at least one liquid droplet. The circumferential wall includes a tube-shaped base, and one or more detachable plates detachably attached to an external surface of the base.
Claims17
A recording apparatus comprising:
- a conveyor which includes a circumferential wall, and which conveys a recording medium placed on an outer circumferential surface of the circumferential wall with rotation of the circumferential wall;
- a recording head including an ejection surface where a plurality of nozzles are open, which records an image to a recording medium being conveyed by the conveyor by ejecting at least one liquid droplet from the nozzles, the ejection surface being positioned so as to face the outer circumferential surface of the circumferential wall,
- wherein the circumferential wall includes a tube shaped base, and one or more detachable plates detachably attached to an external surface of the base such that the external surface of the base has an exposed region where the base is partly exposed;
- a head controller which controls the recording head so as to eject at least one liquid droplet onto the exposed region;
- and
- a cleaning mechanism for cleaning the exposed region,
- wherein the cleaning mechanism is configured to move a blade across the exposed region in a width direction of the circumferential wall while bringing the blade in contact with the exposed region.

- wherein the circumferential wall includes a tube shaped base, and a plurality of the detachable plates are detachably attached to an external surface of the base so that they are aligned thereon in a circumferential direction of the base;
- a head controller which controls the recording head so as to eject at least one liquid droplet on an outer surface of an ejection target plate which is a part of the plurality of the detachable plates,
- wherein a brightness of the outer surface of the ejection target plate is higher than a brightness of the liquid ejected from the recording head;
- and
- an ejection status sensor which senses an ejection failure of a liquid droplet ejected from the recording head to a surface of the ejection target plate.
