An ink level sensing device and associated method. The ink level sensing device includes a near infrared illumination source that emits near infrared light, and a container configured to accommodate a supply of ink containing light absorption material. The device further includes a protruding chamber adjacent to the container. The protruding chamber is configured to accommodate a portion of the supply of ink accommodated by the container. The device also includes a sensor that is configured to receive a signal based on an amount of the light that passes through the protruding chamber. The method includes emitting a light from a near infrared illumination source and directing the light toward a protruding chamber of the ink supply. The method further includes sensing an amount of the light that passes through the protruding chamber in the ink supply. |
