GAP
INPUT
SATO M-84PRO
[X.XXV] GAP - When setting the "gap" threshold, the voltage shown on
[X.XV] 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
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 DSW2-2 =
OFF). Make sure the label is all the way under the sensor.
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 within the following ranges:
Backing with label = 2.0V to 3.5V
Backing without label = Less than 1.0V
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 and 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 and the head is closed.
5. Once the setting is correct, pressing the ENTER key will
accept the setting and advance the next display.
