Advanced Mode
Advanced Mode is used to access several manual adjustment modes in the printer. Each manual
adjustment mode is described in detail in the following sections.
To activate Advanced Mode, complete these steps:
1. Ensure media is loaded and printer power is ON.
2. Press PAUSE for two seconds, all indicators will flash yellow.
3. The STATUS indicator ( ) will show solid yellow, indicating the currently selected mode is:
Manual Media Calibration.
4. Pressing FEED will sequentially cycle through all available modes.
5. Pressing PAUSE will activate the selected mode.
6. Pressing CANCEL will exit Advanced Mode.
Manual Media Calibration
While in Advanced Mode, pressing PAUSE while the Status indicator ( ) is illuminated yellow
will start Manual Media Calibration.
1. The MEDIA indicator () will flash yellow then the Pause indicator () will flash. Open the
printer and verify the media sensor is in the center position for label gap (transmissive)
sensing. Remove 3 inches or 80mm of labels from the liner. Place the label-less area of the
liner over the platen (drive) roller with the leading edge of the first label under the media
guides.
2. Close the printer and press PAUSE once. The MEDIA indicator () will flash as the media
liner is measured. When complete, the Pause indicator
() will begin flashing.
3. Open the printer and reposition the media so that a label is located directly above the
movable sensor. Close the printer.
4. Press PAUSE once. The printer will feed and measure several labels. If the printer is able to
determine the correct media type (gap, black mark or notch) and measure the media length,
the printer will return to the READY state.
This advanced mode is typically used to calibrate the printer to media that is not correctly
recognized during Smart Calibration. If your media uses black mark or notch sensing, ensure the
media sensor is in to the proper location to “see” the mark or notch. If your media is pre-printed,
either on the front of the label or on the back of the liner, position the sensor so that it is in a
position with minimal printing. You may need to perform Manual Media Calibration several times,
moving the media sensor, until the printer completes the calibration process and returns to the
READY state.
