Gap Sensor Sensitivity - SATO /s8408 Operator's Manual

GAP SENSOR SENSITIVITY

This sensor adjustment regulates penetrating ability for media referencing. To establish penetration, upper and
lower voltage levels must be set and the difference between the two voltage levels should be maximized for
optimum performance.
To force auto-calibration, set the Sensor level to 0.0V. Load label media and feed several labels. If labels do not
register properly, perform the manual calibration.
In most cases, the printer will auto-calibrate to the loaded label stock after closing the print head and feeding a
label. The following manual procedure can be performed when labels are not able to register properly after auto-
calibrating.
For proper performance, the sensor must have a voltage difference greater than 0.8V between high and low. If
performing the following procedure does not result in acceptable voltage levels, clean the window over the sensor's
eye with a clean, dry cloth.
Load printer with liner only under the label sensor. Power on the printer.
1.
Using the printer's operator panel, access the Service Mode and then proceed to the Level Offset menu screen
2.
(Figure 6-16).
Using the printer's operator panel, adjust the level offset so that the sensor level is between 0.3V and 0.5V.
3.
Place label media (liner and label) under the sensor.
4.
Read the sensor level now displayed to ensure that this reading is at least 0.8V greater than the low reading
5.
from Step 3.
Add these readings (low value + high value), and divide the sum by two. Record the result.
6.
Advance to the Slice Level menu screen (Figure 6-17).
7.
Adjust the slice level displayed equal to the value recorded in Step 6.
8.
Repeat steps 3 through 8 as required.
