Liquid consuming apparatus and method for controlling liquid consuming apparatus |
| 摘要 |
A liquid consuming apparatus includes a photosensor 80 having a light-emitting portion 82 and a light-receiving portion 84, a holder 21 capable of attachably and detachably holding a liquid container in which a prism 320 having a face that faces the photosensor 80 is arranged, and a determination unit (a failure determination unit 120) that determines status of the photosensor 80 based on the output of the photosensor 80. When the liquid container is installed in the holder 21, the determination unit detects a failure of the photosensor 80 based on a detection signal of the photosensor 80 in the case of causing the light-emitting portion 82 to emit light, and a detection signal of the photosensor 80 in the case of causing the light-emitting portion 82 to turn off the light. |

1. A liquid consuming apparatus comprising:
a photosensor having a light-emitting portion and a light-receiving portion; a holder capable of attachably and detachably holding a liquid container in which a prism having a face that faces the photosensor is arranged; and a controller that determines status of the photosensor based on a detection signal of the photosensor, wherein, when the liquid container is installed in the holder, the controller detects a failure of the photosensor based on the detection signal of the photosensor in the case of the light-emitting portion emitting light, and the detection signal of the photosensor in the case of the light-emitting portion not emitting light. |
