Adjusting the I-mark Sensor Level Manually

NOTE: The I-Mark Sensor is also used for Paper End Sensor. Even if you aren’t using I-Mark media, you will need to ensure the reflective voltage of the media being used is less than 1.0V for the I-Mark sensor, otherwise you may encounter a “PAPER END” error.

1. Go to the SENSOR LEVEL setting screen of SERVICE MODE.
   When the print engine is in online mode, press the LINE button to change the product to offline mode.
   Press the ENTER button.
   The LCD will display the setting mode menu.
   Use the directional keys to select the SERVICE MODE menu and then press the ENTER button.
   Select the SENSOR LEVEL using the directional buttons and then press the ENTER button.
   SENSOR LEVEL shows on the screen.
2. Select MANUAL using the directional buttons and then press the ENTER button.

The light emission level adjustment of the I-mark sensor is shown on the LCD.

3. On the SENSOR LEVEL I-MARK(E) screen, press the directional 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 I-mark sensor is now shown on the LCD.

First, adjust the “Low” reception level (voltage) of the I-mark sensor.

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

Physically place the media with the portion without the I-mark resting over the I-mark 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 up/down buttons to change ADJUST LEVEL until the I-MARK(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 I-MARK(R) value from the above procedure. This is the “Low” level value for the I-mark sensor.

Next, check the “High” level (voltage) of the I-mark sensor.

8. Unlock the media feed and media sensor assembly.

9. Physically place the I-mark media again, so that the media sensor can sense the I-mark.

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 I-MARK(R) value. This is the “High” level value for the I-mark sensor.

12. 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 1.0V, repeat the procedure from steps 4 through 12. If after multiple attempts, clean or replace the sensor.

13 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.

14 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 automatically.

15 If you completed with I-mark sensor level adjustment, press the FUNCTION
button to return to the SERVICE MODE menu. Otherwise, continue with the Gap sensor level adjustment.
