a soft bristle brush or vacuum.

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.

5 Clean the label taken sensor with a cotton swab moistened with
isopropyl alcohol.
