S84/86-ex GAP Sensor Manual Calibration Procedure

Adjusting the Gap Sensor Level Manually

The adjustment procedure for the Gap sensor level is as follows:

1 Continue the procedure from step 15 of Adjusting the I-mark Sensor Level Manually.

If you only want to adjust the Gap sensor level, after selecting MANUAL in the SENSOR LEVEL screen, press ENTER button repeatedly until SENSOR LEVEL GAP(E) screen is shown.

2 On the SENSOR LEVEL GAP(E) screen, press the / buttons to set ADJUST LEVEL to 2 and then press the ENTER button.

The adjustment range of ADJUST LEVEL is from 0 to 3. We recommend using the initial value, which is 2.

The light reception level adjustment of the Gap sensor is shown on the LCD.

First, adjust the “Low” reception level (voltage) of the Gap sensor.

3 Open the top cover and unlock the media feed and media sensor assembly.

4 Physically place the liner  without the label resting over the Gap sensor.

5 Press the media feed and media sensor assembly  down to lock it.

To get the correct adjustment result, close the media sensor assembly before performing the adjustment.

6 Press the / buttons to change ADJUST LEVEL until the GAP(R) value is 1.0 V or lower.

The adjustment range of ADJUST LEVEL is from 0 to 127.

Note: The ADJUST LEVEL manipulates the potentiometer that will be, therefore, reset to 90, the default value when replacing the PCB or initializing the settings.

7 Take a note of the GAP(R) value from the above procedure. This is the “Low” level value for the Gap sensor.

Next, check the “High” level (voltage) of the Gap sensor.

8 Unlock the media feed and media sensor assembly.

9 Physically place the label resting over the Gap sensor.

10 Press the media feed and media sensor assembly down to lock it.

To get the correct adjustment result, close the media sensor assembly before performing the

adjustment.

11 Check the new GAP(R) value. This is the “High” level value for the Gap sensor.

If the difference between the “High” and the “Low” level values is 1.0 V or more, then the adjustment has satisfied the criteria.

If the difference between the “High” and the “Low” level values is less than 1.0 V, repeat the procedure from steps 3 through 11.

12 Press the ENTER button to confirm the setting and proceed to slice level adjustment screen.

Note: If you are having difficulties in adjusting the sensor level properly, clean the media sensor portion. If the problem persists, contact your SATO reseller or technical support center to replace the media sensor.

13 Press the / buttons to change the SLICE LEVEL and then press the ENTER button.

The slice level can be set to 0.0 V, or from 0.3 V to 2.9 V. (adjustable in increments of 0.1 V). If you set the SLICE LEVEL to 0.0 V, the print engine sets the slice level voltage automatically.
