Section 2. Installation and Configuration

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 for this is:

(High Voltage Level + Low Voltage Level) x 0.5 = Start Value

1.Insert a label into the sensor (see Section 3: Cleaning and Maintenance for location of the sensors) 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).

2.Now pull the label forward until the “eye” mark is positioned under the sensor (the voltage reading should be at its highest point). Record the voltage shown on the top line of the LCD panel. The voltage ranges measured should be within the following ranges:

Label Only

Eye Mark

 

 

 

 

Less than 1.0V

2.5V to 3.5V

 

 

 

 

If the measured values are outside this range, you may have trouble in 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 pressed for more than two seconds, it will automatically go into the fast scroll mode. The reading will advance to a setting of 4.9 (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 Calendar Set display.

6.Repeat this procedure using values slightly higher or lower until the value that gives adequate performance is found. If adequate performance cannot be obtained, then the label stock or printed “Eye” mark has too much variation in its reflectance and a better quality stock should be used.

Calendar Set

If the Calendar Option is installed in the printer, the date and time can be set manually using the LCD Display or via the <ESC>WT Calendar Set command (see Page 4-80). The last setting, set either manually via software command, received by the printer will be the value used.

CALENDAR ENABLED

NO YES
