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 seven selections for Meter: Paper Out, Paper
Motion, Ribbon Weld, Temp Sensor, and Keypad. Power and Platen will not be discussed in
this manual because they are used on the printer production line only.
Accessing the Meter Measurement Tests:
Step 1.
Take the printer offline and place it in Tech Access Mode.
Step 2.
With the printer display reading OFFLINE, depress the Menu/Back key and use the
▲/▼ keys to scroll to Test
Step 3.
Press Enter and scroll (
▲ Key) to Diag.
Step 4.
Press Enter and scroll (
▲ Key) to Meter.
Step 5.
Press Enter and scroll (
▲ Key) to one of the following measurement tests at Level 3.
Each Meter Test is initiated by pressing the Enter key when the desired selection
displays.
Paper Out Sensor
The Paper Out Sensor should read less than .2 volts with paper removed and greater than 4
volts with paper installed. No other operator actions are required during this test.
Paper Motion Sensor
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.
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.
Temp Sensor
The printer has a sensor on the Engine Controller Board for monitoring the air temperature in
the area of the engine controller CBA. When Temp Sensor is selected, the display shows the
temperature in milli-volts.
Keypad
This test verifies that the logic board can receive a signal from each key on the control panel.
Once you have entered the Keypad Test, depressing each key should make its label appear on
the Control Panel Display (i.e., Mode, View, Line Feed, etc.). Exit the Keypad Test by depressing
the Clear key three times.
