ADJUSTMENT PROCEDURES
This chapter covers all of the printer and printer accessory adjustments. These adjustments include mechanical
adjustments required following the replacement of components and assemblies, in addition to, the operational
adjustments required following a job change.
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.
2 Find label sensor adjustment handle (Figure 6-4) located between the upper and lower print assemblies.
3 Manually move the adjustment handle to the left or right as required to properly position the label sensor.
4 Test print a label to determine if the label sensor is properly aligned.
Figure 6-4, Label Sensor Positioning
NOTE: There are two markers on the front face of the media stabilizer. The marker
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.
