Abstract: In an embodiment, a fluid ejection device includes an ink slot formed in a printhead die. The fluid ejection device also includes a printhead-integrated ink level sensor (PILS) to sense an ink level of a chamber in fluid communication with the slot, and a clearing resistor circuit disposed within the chamber to clear the chamber of ink.
