Troubleshooting Guide

Adjusting the Ribbon Sensor Sensitivity

The Ribbon Sensor system detects the presence of a ribbon in the system. The Media Type parameter value determines how the printer uses the sensor (see Media Settings section, Setting the Printing Method). In Direct Thermal mode, the printer uses the sensor to verify a ribbon is not installed. In Thermal Transfer mode the printer uses the sensor to detect the ribbon installation and the trailer when the ribbon supply is empty. Follow the procedure based on the type of problem reported by the printer.

Printer Displays “Remove Ribbon” Message in Direct Thermal Mode

The printer displays this message when Ribbon Sensor sensitivity level is less than required. The Ribbon Sensor is not receiving light reflecting from the back of the printhead bracket. Resolving this issue involves raising Ribbon Sensor Sensitivity to a level that will allow the sensor to detect the reflective material on the back of the printhead bracket. (Note: If current sensitivity value accommodated a ribbon in Thermal Transfer mode, note the Ribbon Sense parameter before the adjustment. This value will be required if using the printer in Thermal Transfer mode at a later time.)
