4. Media Sensor Calibration

You need to calibrate the media sensor to print properly. WS printers
provide transmissive and reflective sensor calibration. Take the following
steps to use them.

1. Make sure the media is properly loaded, the print module is closed and
the printer’s power switch is set to the OFF position.

2. Press and hold the FEED button and turn on the printer.

3. Both status lights illuminate solid orange for a few seconds. Next, they
turn to green shortly and then turn to other colors. Do one of the
following to select the sensor:

- If you want to calibrate the transmissive sensor, when LED 1 turns to
green and LED 2 turns to red, release the FEED button immediately.
- If you want to calibrate the reflective sensor, when LED 1 turns to green
and LED 2 turns to orange, release the FEED button immediately.

4 Press the FEED button. The media calibration is complete after the
printer feeds 3-4 labels and stops.
