Cleaning the Label Sensors

There are two label sensors on the 3240 printer that require regular cleaning:
the label taken sensor and the 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. Disengage the printhead by rotating the head lift lever clockwise until the
printhead releases.
4. Remove the media and ribbon (if necessary).
5. Clean the label taken sensor with a cotton swab moistened with isopropyl
alcohol. Refer to the illustration.
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.
Note: You may want to slide the label gap sensor toward the outboard edge of the
printer for better access. Make sure you return the label gap sensor to its original
position when you finish cleaning.
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.
