Abstract
An ink identification and detection system includes an imaging apparatus. An ink tank is mounted to the imaging apparatus. The ink tank has a transparent portion. An ink is contained in the ink tank. The ink includes a fluorescing material. An ink detection device is communicatively coupled to a controller. The ink detection device is configured to emit light in a non-visible spectrum of light through the transparent portion to the ink, and is configured to detect light in a visible or near-infrared spectrum of light emitted through the transparent portion by the fluorescing material in the ink. The ink detection device supplies a signal representing the detected light to the controller for identifying the ink.
