Abstract
A recording device includes a head including a plurality of nozzles that are arranged at predetermined intervals in a first direction, the plurality of nozzles being configured to eject liquid, and a controller. The controller is configured to, in a case where the number of the abnormal nozzles among the plurality of nozzles is equal to or greater than the predetermined number and the number of the abnormal nozzles, among a part of the plurality of nozzles in which an interval in the first direction is a preset interval longer than the predetermined interval, is less than the predetermined number, cause the head to eject liquid from the part of nozzles to record an image with a resolution in which a resolution in the first direction is lower than a resolution corresponding to the predetermined interval.
Claims15
A recording device comprising:
- a head including a plurality of nozzles that are arranged at predetermined intervals in a first direction, the plurality of nozzles being configured to eject liquid;
- a relative movement unit configured to relatively move the head, with respect to a recording medium, in a second direction intersecting the first direction;
- a storage unit configured to store abnormal nozzle information related to whether a number of abnormal nozzles among the plurality of nozzles is equal to or greater than a predetermined number, the abnormal nozzles having an abnormality in liquid ejection;
- and
- a controller,
- wherein, in response to receiving a recording instruction signal instructing to perform recording on the recording medium, the controller is configured to:
- in a case where the abnormal nozzle information indicates that the number of the abnormal nozzles among the plurality of nozzles is less than the predetermined number, perform a first recording processing of causing the head to eject liquid from the plurality of nozzles while causing the relative movement unit to move the head, with respect to the recording medium, in the second direction to record an image on the recording medium with a resolution in which a resolution in the first direction corresponds to the predetermined interval;
- and
- in a case where the abnormal nozzle information indicates that the number of the abnormal nozzles among the plurality of nozzles is equal to or greater than the predetermined number and indicates that the number of the abnormal nozzles, among a part of the plurality of nozzles in which an interval in the first direction is a preset interval longer than the predetermined interval, is less than the predetermined number, perform a second recording processing of causing the head to eject liquid from the part of nozzles while causing the relative movement unit to move the head, with respect to the recording medium, in the second direction to record an image on the recording medium with a resolution in which a resolution in the first direction is lower than a resolution corresponding to the predetermined interval.
6 more elements
A recording device comprising:
- a head including:
- a plurality of first nozzles that are arranged in a first direction, the plurality of first nozzles being configured to eject liquid supplied from a first flow path connected to a liquid storage portion configured to store the liquid;
- and
- a plurality of second nozzles that are arranged in the first direction, the plurality of second nozzles being configured to eject liquid supplied from a second flow path connected to the liquid storage portion, the second flow path being different from the first flow path;
- a relative movement unit configured to relatively move the head, with respect to a recording medium, in a second direction intersecting the first direction;
- a storage unit configured to store abnormal nozzle information related to whether a number of abnormal nozzles among the plurality of first nozzles is equal to or greater than a first predetermined number, the abnormal nozzles having an abnormality in liquid ejection, and whether the number of the abnormal nozzles among the plurality of second nozzles is equal to or greater than a second predetermined number, and
- a controller,
- wherein, in response to receiving a recording instruction signal instructing to perform recording on the recording medium, the controller is configured to:
- in a case where the abnormal nozzle information indicates that the number of the abnormal nozzles among the plurality of first nozzles is less than the first predetermined number and the number of the abnormal nozzles among the plurality of second nozzles is less than the second predetermined number, perform a first recording processing of causing the head to eject liquid from the plurality of first nozzles and to eject liquid from the plurality of second nozzles to perform recording on the recording medium, while causing the relative movement unit to relatively move the head, with respect to the recording medium, in the second direction;
- and
- in a case where the abnormal nozzle information indicates that the number of the abnormal nozzles among the plurality of first nozzles is equal to or greater than the first predetermined number and the number of the abnormal nozzles among the plurality of second nozzles is less than the second predetermined number, perform a second recording processing of causing the head not to eject liquid from the plurality of first nozzles and to eject liquid from the plurality of second nozzles to perform recording on the recording medium, while causing the relative movement unit to relatively move the head, with respect to the recording medium, in the second direction.
