♦ For the On-Demand sensor, hold a white label against the sensor as
shown. When you cover the sensor with a label, the values change on
the screen. The valid range is between 3.0 and 5.0. If the sensor is
covered by a black mark, the valid range is between 0 and 1.5.
4. The value listed for PH Temperature is the current temperature of the
printhead. The valid range is between 5 and 60 Celsius. The
temperature of the printhead depends upon the number of labels
printed and the operating environment. If the temperature is greater
than 60, the printer will not print.

test again.
Note: If the value is not within the ranges, make a note of the values
