Ink Level Detection in a Printer
To monitor the ink level in a printer tray
Description
Behind each of the four print rollers on a color printing machine is an ink tray. The transducer of the U-GAGE Q45UR ultrasonic sensor is mounted approximately 100-200 mm above the ink in the tray.
As the ink level changes, the analog output of the Q45UR gives a reading to the larger refill tank that contains the ink supply. When the ink drops to the minimum level, the sensor signals the refill tank to add more ink to the tray.
