Cleaning the Sensors
Brush or vacuum any accumulated paper lint and dust away from the printer sensors.
Refer to Figure 23. The reflective sensor, transmissive sensor, and ribbon sensor
should be cleaned on a regular basis to ensure proper operation of the printer. For
printers with the value peel-off, power peel-off, and/or power rewind option(s)
installed, clean the take label sensor.
