LABEL SENSOR POSITIONING
The label sensor assembly provides a mounting apparatus for the eye-mark, gap, and paper-end sensors. Position
adjustment of the label sensor is not required when using standard label media.
When non-standard media is used, place a section of the media on the media ramp oriented as if loaded for
printing. Manually grasp the sensor assembly and move it laterally so that the sensor indicators embossed in its
side are aligned with the reference marks on the media.
1 Open the right housing cover to access print assembly (1, Figure 6-7).
2 Find label sensor adjustment knob (2) located behind lower print assembly (1).
3 Manually move knob (2) to the left or right as required to properly position label sensor (3).
4 Test print a label to determine if label sensor (3) is properly aligned.
Figure 6-7, Label Sensor Positioning
NOTE: The label sensor adjustment knob is green colored ABS plastic.
NOTE: There are two lines on the front face of the label sensor. The line closes to the
printer’s center frame references the location of the eye-mark sensor, the one furthest
out references the gap sensor Adjust according to the type of media to be used.
NOTE: Sensor positioning may also be achieved by measuring from the printer’s
center frame outward to the specified distance for sensor/reference mark alignment.
Refer to Figure 9-3 in the Appendix unit of this manual for applicable dimensions.
