Cleaning the Label and Ribbon Sensors
There are three label sensors and a ribbon sensor on the 3600 printer that
require cleaning: the label taken sensor, the label mark sensor, the label gap
sensor, and the ribbon motion sensor.
To clean the sensors
1. Remove the media cover.
2. Raise the printhead by rotating the head lift lever clockwise until the
printhead releases.
3. Remove the media from the paper path and the ribbon (if installed) from
the TTR hubs.
4. Clean the label taken sensor and the label mark sensor with a cotton swab
moistened with isopropyl alcohol.
