3 Test the Ink Count Sensor by running
the Monitor Sensors test in Service
Diagnostics.
Insert the clean, eraser end of a pencil
thru the lowermost oval slot in the Ink
Loader. Actuate the appropriate sensor
by sliding the pencil down the white
channel guide until the sensor is
tripped. If the sensor is functional, a
state change appears on the Control
Panel as <color> Ink Present H. When
released, the reading changes to L.
The test only displays a reading when a
sensor change occurs. If a flag is
stuck, no reading is displayed.
