STEP PROCEDURE
2. Strip the label from the backing and insert the backing strip under the
sensor and close the Label Lid. Record the voltage shown on the top
line of the LCD panel. The voltage ranges measured should be withing
the following range.
Backing without label = 1.0V or less
Backing with label = 2.0V to 3.5V
If the measured values are outside this range, you may have trouble
finding a value that will work properly under all conditions. If this is
the case, a higher quality label may be needed to get adequate
performance.
3. Calculate the starting point voltage using the formula.
4. Use the LINE /FEED keys to step the counter to the desired setting.
The reading will advance to a setting of 4.9 (the maximum voltage). If a
value of “0.0” is set, the printer will automatically set the level each
time the printer is powered on with labels loaded or the head is closed.
5. Once the setting is correct, pressing the ENTER key will accept the
setting and advance to the next display.

EYE - When setting the “EYE” threshold, the voltage must be measured with nothing but the
label under the sensor and then again with the printed “EYE” mark under the sensor.
The formula to be used for this is:
(High Voltage Level + Low Voltage Level) x 0.5 = Start Value

STEP PROCEDURE
1. Insert a label into the sensor and close the Label Hold-Down. Make
sure the printed “EYE” mark is not under the sensor. Record the
voltage shown on the top line of the LCD panel. This line should have
the message “EYE” on the top line (DIP switch DSW2-2 = ON).
