Cleaning the Label Sensors
Three label sensors on the printer require regular cleaning:
•
Label taken sensor
•
Label mark sensor
•
Label gap sensor
To clean the label sensors
1. Turn the On/Off switch to the off position and remove the power cord.
2. Remove the media cover.
3. Rotate the head lift lever clockwise to release the printhead. Rotating the head lift
lever raises the printhead to allow access to the label mark sensor.
4. Remove the media and ribbon (if necessary).
5. Clean the label taken sensor with a cotton swab moistened with isopropyl alcohol.
6. Pull down on the lower media guide to expose the label gap sensor. Using a
cleaning brush or vacuum, remove all debris and dust from the label gap sensor.
7. Clean the label gap sensor with a cotton swab and alcohol.
8. Replace the media and ribbon.
9. Engage the printhead by rotating the head lift lever counterclockwise until it locks
in place.
10. Replace the media cover.
