Adjustments and Maintenance
2-1
2.0 Introduction
This section covers the necessary maintenance and alignment procedures for the printer.
2.1 Media Sensor Calibration
This printer can use many different media compositions, configurations and colors. In addition to
adjusting the Media Sensor and selecting the ‘
SENSOR TYPE
,’ to ensure that each label is detected
correctly and reliably, calibration is required. There are three different calibration methods.
2.1.1 Quick Calibration
This is the easiest calibration method and should work for most die-cut and reflective media types.

This procedure is not required for continuous media. If ‘Uncalibrated’ is displayed, follow the Standard
Calibration procedure in Section 2.1.2.
Perform a Quick Calibration as follows:
 Ensure that media is loaded, that the Media Sensor is adjusted, and that the printer is idle.
 Press and hold the Key.
The printer will begin advancing media; allow at least one label
gap or mark to pass through the sensor.
Upon successful completion, ‘
CALIBRATION COMPLETE
’ will be displayed, the printer will feed to the
next label TOF and ‘
READY
’ will be displayed. (A ‘
WARNING LOW BACKING
’ message may appear if
using notched media or media on a transparent liner; however, the calibration was successful).

Note: Die-cut media containing large gaps may require a change in the ‘PAPER OUT DISTANCE’ setting; see
the Operator’s Manual for details.
Calibration Hints:
In certain cases, the printer may have trouble differentiating between the label and
liner.
If ‘
CANNOT CALIBRATE
’ is displayed, or if the printer stops feeding mid-label then try the following:

Press and hold the Key to allow two gaps (or marks) to pass through under the sensor.
If ‘
CANNOT CALIBRATE
’ is displayed again, or if the printer stops feeding mid-label then try the
following:
 Press and hold the Key to allow three or more gaps (or marks) to pass through the sensor.
If this method fails, use the Standard Calibration method described in Section 2.1.2.
