2.2 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. Depending upon the printer
type, there are different calibration methods.

2.2.1 Calibrating Non-Display Models

In Calibration Mode, button functions adjust the Media Sensor to the media being used.
Calibration can be performed either automatically or manually, as detailed below.
Notes: Printer faults remain disabled during calibration, but can still occur while printing

Test Labels. Also, if needed, factory defaults can be restored.
