CLEANING THE SENSOR
The I-Mark and gap sensors are used to control the positioning of the label. The gap sensor is a
transmissive see-thru sensor that detects the edge of the label by sensing through the backing paper
which is translucent and detecting the presence of the opaque label. The I-Mark sensor detects the black
I-Mark found on I-Mark labels.
So when dust, dirt or other foreign matter interferes with the light path of the any sensor, erratic label
positioning occurs. The sensors, both housed in the same area, should thus be cleaned regularly, after
every two rolls of labels.
1. Turn the printer OFF and remove the power cable.
2. Open the Top Cover.
3. Locate the sensor located next to the yellow screwdriver, near
the left-hand side label guide so that it moves whenever the
Label Guide are adjusted for different media widths.
4. Apply Thermal Print Head Cleaner to a cotton swab.
5. Use the cotton swab to clean any foreign matter from the
exposed surface of the sensor by inserting the cotton tip in the
paper slot and briskly cleaning it with a back and forth motion.
