2.3.3.3 Meter
The Meter Parameter provides real-time dynamic measurements of various sensor readings within
the printer. They can be used to adjust the sensor for optimum performance or to test sensors to
ensure that they are operating properly. These test measurements are displayed directly on the
Control Panel Display. There are several selections for Meter: Paper Out, Paper Motion,
Shuttle, Ribbon Weld, Supply Voltage, Hambus1, Hambus2,
and
Keypad.
Accessing the Meter Measurement Tests:
Step 1.
Take the printer offline and place it in Tech Access Mode.

2.3.3.3.1 Paper Out
The Paper Out Sensor should read less than .2 volts with paper removed and tractor door closed,
and greater than 4 volts with paper installed. No other operator actions are required during this test.
2.3.3.3.2 Paper Motion
The Paper Motion Sensor only needs to have a differential of greater than 2 volts between the high
and low reading to function properly. No other operator actions are required during this test.
2.3.3.3.3 Shuttle
Displays the output of the shuttle position sensor.
2.3.3.3.4 Ribbon Weld
The Ribbon Weld Sensor is read by sliding a piece of white paper between the ribbon and the
sensor. The readings should be greater than 4 volts uncovered and less than .2 volts covered.
2.3.3.3.5 Supply Voltage
Displays the voltage level of the power supply.
2.3.3.3.6 Hambus1 and Hambus2
Displays the voltage level of the hammer drive busses for odd and even hammers. These
parameters are used for advanced hammer circuit debugging.
