GAP - When setting the "GAP" threshold, the voltage shown on the top line of the display
must be measured with nothing but the backing in the sensor and then again with a label
still attached to the backing. The formula to be used for setting the threshold is:
(High Voltage Level + Low Voltage Level) x 0.5 = Start Value
STEP PROCEDURE
1. Insert a label still attached to the backing into the sensor and close
the Label Hold-Down. Record the voltage shown on the top line of
the LCD panel. This line should have the message "GAP" on the top
line (DIP switch DSW - = OFF). Make sure the label is all the way
under the sensor.
. 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 within
the following range.
Backing without label = 0.5V or less
Backing with label = 1.0V 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 Online Feed display.
