Liquid Consuming Apparatus and Method for Controlling Liquid Consuming Apparatus |
| 摘要 |
A liquid consuming apparatus 200 includes a photosensor 80 capable of facing a prism 320 provided in a liquid container, and a control unit 100. The control unit 100 performs remaining status determination processing for determining remaining status of liquid in the liquid container, based on a detection signal detected by the photosensor 80 due to reflection from the prism 320 when light is emitted by the photosensor 80, performs ambient light determining processing for determining whether or not the remaining status determination processing is affected by ambient light, based on the detection signal detected by the photosensor 80 when light is not emitted by the photosensor 80, and continues printing until the end of printing on a sheet that is being printed, even if the control unit 100 determines that the influence of ambient light is present, by the ambient light determination processing during execution of printing. |

1. A liquid consuming apparatus comprising:
a photosensor having a light-emitting portion and a light-receiving portion and capable of facing a prism provided in a liquid container; and a control unit that controls printing, wherein the control unit performs remaining status determination processing for determining remaining status of liquid in the liquid container, based on a detection signal detected by the photosensor due to reflection from the prism when light is emitted by the photosensor, the control unit performs ambient light determination processing for determining whether or not the remaining status determination processing is affected by ambient light, based on the detection signal detected by the photosensor when light is not emitted by the photosensor, and the control unit continues printing until the end of printing on a sheet that is currently being printed, even if the control unit determines, during execution of the printing, that the influence of the ambient light is present, by the ambient light determination processing. |
