Meter Parameter (Menu Level 2)
This parameter has nine selections. The sensor tests that are available under this parameter
can be used to adjust the sensor for optimum performance or to test sensors to ensure that they
are operating properly.
Meter selections (Menu Level 3)
Sht Sen (see explanation below)
Pap Out (see explanation below)
Pap Mot (see explanation below)
Rib Mot (see explanation below)
Tmp Sen (reads current voltage drop across the thermistor)
Power (used on printer Production Line only)
Platen (used on printer Production Line only)
Current (used on printer Production Line only)
Keypad (displays each key name when it is depressed)
Each Meter Test is initiated by depressing the ENTER Key when the desired selection is
displayed.
The first 4 tests are used to check positioning of the sensor itself. Each sensor is checked in a
"covered" and "uncovered" mode.
For the Paper Out and Paper Motion sensors, depress the ENTER Key then check them with
paper installed (covered) and paper removed (uncovered). The Paper Out Sensor should read
less than .2 volts with paper removed and greater than 4 volts with paper installed. The Paper
Motion Sensor only needs to have a differential of greater than 2 volts between the high and
low reading to function properly.
The Shuttle Motion Sensor should read less than 0.5 volts with the open portion of the upper
gear over it (uncovered), and greater than 4.5 volts with the solid portion of the gear over it
(covered).
The Ribbon Motion Sensor is read with the silver portion of the wheel inside the Ribbon
Cartridge over it (uncovered), then with the black portion over it (covered). The readings
should be greater than 4V uncovered and less than .2V covered.
Motors Parameter (Menu Level 2)
This parameter allows you to test the Shuttle Motor and Ribbon Motor. They can be tested at
the current selection (Default) or you can select a variety of speeds at which to test them. (See
Sht Spd Parameter and Rib Spd Parameter.)
Motors selections (Menu Level 3)
Ribbon
Shuttle
The selected test is initiated by depressing the ENTER Key. After the motor reaches its
assigned speed the test can be stopped by depressing the ENTER Key again. This sequence
may be repeated until you are satisfied with the operation of the motor.
