Method for controlling light emitting portion for liquid container and printing apparatus
The present invention reduces a variation in brightness among light emitting portions provided in a plurality of liquid containers to decrease power required to drive the light emitting portions, while allowing the light emitting portions to appropriately function as reporting means. Thus, to illumi...

description | The present invention reduces a variation in brightness among light emitting portions provided in a plurality of liquid containers to decrease power required to drive the light emitting portions, while allowing the light emitting portions to appropriately function as reporting means. Thus, to illuminate the light emitting portions provided in the plurality of ink tanks, a driving pulse for each of the plurality of light emitting portions is modulated to control rates of a light emission period and a light emission halted period during a unit time. Further, the light emission period of at least one of the plurality of light emitting portions is in the light emission halted period of another at least one of the plurality of light emitting portions. |
