LIQUID EJECTING HEAD UNIT, LIQUID EJECTING APPARATUS, WIPING METHOD, AND PRINTING METHOD

摘要

A liquid ejecting head unit which includes a liquid ejecting head which includes a nozzle surface provided with nozzles, the nozzle surface being on a plane defined by two directions including a first and a second directions intersecting each other, a wiping unit comprising a wiper parallel to the first direction and configured to perform relative movement in the second direction between the wiper and the nozzle surface to wipe the nozzle surface, a recess defined by an edge provided along the first direction on the nozzle surface, and a controller for filling the recess with a liquid which spills from at least one nozzle among the nozzles, and for wiping the nozzle surface after wiping the recess.

1. A liquid ejecting head unit comprising:
a liquid ejecting head which includes a nozzle surface provided with nozzles, the nozzle surface being on a plane defined by two directions including a first and a second directions intersecting each other; a wiping unit comprising a wiper parallel to the first direction and configured to perform relative movement in the second direction between the wiper and the nozzle surface to wipe the nozzle surface; a recess defined by an edge provided along the first direction on the nozzle surface; and a controller configured to control the liquid ejecting head to fill the recess with a liquid which spills from at least one nozzle among the nozzles, and control the wiping unit to wipe the nozzle surface after wiping the recess which is filled with the liquid, and wherein in a case in which the nozzles are projected in the second direction in relation to a virtual line parallel to the first direction, an area in which the nozzles are distributed on the virtual line is included in an area in which the recess which is filled with the liquid is distributed on the virtual line.
