B.4.2 Manual Media Sensor Calibration

The Manual Media Sensor Calibration procedure should be used in cases where the printer continues to suffer

from media sensing problems after performing or attempting to perform the Auto Media Sensor Calibration.



Before calibrating, be sure the media sensor is set for the appropriate media type; also, ensure that the

Printhead Carrier Assembly is latched down and the cover is closed.

To manually calibrate the media sensor, proceed as follows:

1. Hold the

Button and power-up the printer. Continue to hold the button until the Paused Light turns

OFF; then release the button. Next, press and hold the

Button until the Paused Light illuminates; then

release the button.

2. Place the media with the backing attached (if any) over the media sensor (see Section 2.3 for the

location), close the Printhead Carrier Assembly, and then press the

Button. The Fault Light will flash as

the material is analyzed.

3. Position the backing material or the black (reflective) mark over the media sensor, close the Printhead

Carrier Assembly, and then press the

Button. The Fault Light will flash as the mark is analyzed.

4. Remove all the material from the media sensor, close the Printhead Carrier Assembly, and then press the

Button. The Fault Light will flash as the condition is analyzed.

5. Simultaneously and briefly press the

Buttons to accept the calibration for test and exit the Media

Sensor Calibration. One of the following indicators will flash five times to denote the result of the manual

calibration attempt:

Paused Light = Successful calibration. Proceed to Step 6.

Fault Light = Unsuccessful calibration. Retry the procedure beginning at Step 1.

6. Use the

Button to feed a label and the

Button to print a test label, in order to verify the current

calibration.



If you wish to discard the changes and revert back to the previous calibration simply turn OFF the printer

before Step 7.

7. Now save the changes and resume Normal Mode by pressing the

Buttons simultaneously and

briefly. Wait until the Paused Light goes OFF.
