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.
