Liquid ejection device, method, and non-transitory, computer-readable storage medium for liquid ejection device

A non-transitory, computer-readable storage medium storing computer-readable instructions therein that, when executed by at least one processor of a liquid ejection device comprising a liquid ejection head comprising an ejection surface comprising a plurality of ejection nozzles configured to eject liquid to record an image, a conveyor mechanism configured to convey a recording medium in a first direction, and a liquid discharging device configured to discharge the liquid from at least one of the plurality of ejection nozzles, instruct the liquid ejection device to execute processes, comprising:

• determining a dimension in a second direction of the recording medium conveyed by the conveyor mechanism, wherein the second direction is orthogonal to the first direction;
• and
• controlling the liquid discharging device to discharge the liquid according to a liquid discharging process after the liquid ejection head records an image onto the recording medium, the dimension in the second direction of which has been determined, wherein in the liquid discharging process, an amount of liquid discharged from each of one or more first ejection nozzles, which is one or more ejection nozzles, of the plurality of ejection nozzles, that correspond to an edge portion of the recording medium based on the dimension in the second direction, is greater than an amount of liquid discharged from each of one or more second ejection nozzles, which is one or more ejection nozzles, of the plurality of ejection nozzles, that correspond to an inward area of the recording medium, the inward area of the recording medium being an area of the recording medium that is between a first edge and a second edge of the recording medium in the second direction and excluding the edge portion of the recording medium.

A method of discharging liquid from a liquid ejection device comprising a liquid ejection head comprising an ejection surface comprising a plurality of ejection nozzles configured to eject liquid to record an image, a conveyor mechanism configured to convey a recording medium in a first direction, and a liquid discharging device configured to discharge the liquid from at least one of the plurality of ejection nozzles, the method comprising:

• determining a dimension in a second direction of the recording medium conveyed by the conveyor mechanism, wherein the second direction is orthogonal to the first direction;
• controlling the liquid discharging device to discharge the liquid according to a liquid discharging process after the liquid ejection head records an image onto the recording medium, the dimension in the second direction of which has been determined, wherein in the liquid discharging process, an amount of liquid discharged from each of one or more first ejection nozzles, which is one or more ejection nozzles, of the plurality of ejection nozzles, that correspond to an edge portion of the recording medium based on the dimension in the second direction, is greater than an amount of liquid discharged from each of one or more second ejection nozzles, which is one or more ejection nozzles, of the plurality of ejection nozzles, that correspond to an inward area of the recording medium, the inward area of the recording medium being an area of the recording medium that is between a first edge and a second edge of the recording medium in the second direction and excluding the edge portion of the recording medium.
