Ink Level Sensor Test
This test determines if the ink level sensor is working correctly. To
run the test, select Ink Level Sensor Test from the BASE SENSOR
TESTS menu. The following screen is displayed:
First the printheads are uncapped. The printheads move to the
middle of the frame so that the servicer has unobstructed access to
the ink-level sensor. Once the printheads have been presented, the
analog ink-level sensor value begins updating in real time. The
servicer can affect this value by waving a magnet in front of the
sensor.
When the test is ended using the operator panel (Return or Stop),
the carrier is homed and the printheads are capped.
