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 in 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).
2. Now pull the label forward until the "eye" mark is positioned under
the sensor (the voltage reading shown on the top line of LCD panel).
The voltage ranges measured should be within the following ranges:
Label Only = 0.3 - 0.5V
Eye-mark = Equal to or greater than 1.2V
above the low value.
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 key to step the counter to the desired setting. The
display will increment one step for each time the LINE key is pressed.
If the LINE key is held down for more than two seconds, it will
automatically go into the fast scroll mode. The reading will advance
to a setting of 3.3 (the maximum voltage) after which it will
automatically wrap and start at "0.0" again. 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 FEED key will accept the
setting and advance to the Auto Online Feed display.
