Reflective Media Sensor Adjustment

The Reflective Media Sensor is placed into operation for those applications

where the sensing of Black Marks on the underside of the media is desired.

For the 105S printer, the Reflective Media Sensor is an option that is installed in

place of the lower section of the Transmissive Media Sensor. Position

adjustment is available across the total width of the media. With the Reflective

Media Sensor installed, the upper section of the Transmissive Media Sensor is

not operational.

For the 160S and 105Se printers, the position of the Reflective Media Sensor is

fixed against the Mainframe and has no adjustment. Switches on the rear of the

printers are used to configure the printers for operation with either the

Reflective Media Sensor or the Transmissive Media Sensor previously discussed.

Transmissive Media Sensor and Ribbon Sensor Sensitivity Adjustment

NOTE: This adjustment is initially performed by Zebra Technologies during

final printer inspection. Under normal circumstances, further adjustments should

not be necessary. The exception is when media with exceptionally thick or thin

backing material is being used in the printer.

Perform the following procedure if the Paper/Ribbon LED comes ON when:

a. In the thermal transfer printing mode, media and ribbon are properly installed

b. In the direct thermal printing mode, media only is properly installed.

Sensitivity Adjustment Procedure

1. Turn the printer OFF.

2. Raise the Media Cover and open the Printhead.

3. Load at least 12 inches of blank backing material (no labels) under the

Printhead.

NOTE: Insure that blank backing material extends behind the Printhead and is

positioned between the upper and lower sections of the Transmissive Media

Sensor.

4. Remove the ribbon. (Sliding the ribbon as far to the right as possible will

have the same effect as removing it.)

5. Close the Printhead.

6. Press the Pause, Feed, and Cancel keys while turning the printer ON. Once

the printer is ON, release all three keys.

The following two sets of LEDs will begin flickering to signify that the

automatic sensor adjustment has been made.

The PRINTHEAD and PAPER/RIBBON LEDs.

The DARKEN and POSITION LEDs.

NOTE: If only one pair of LEDs is flickering, it indicates that the adjustment

was not successful. Go back to step 1 and start over.
