Troubleshooting Guide

Adjusting the Black Bar Sensor Sensitivity

The printer uses the Black Bar Sensor system to detect black bar on the back of label stock. Setting the Label Gap parameter value to Black Bar (0.01 inches) causes the printer to use this method. Verify that the Label Gap is set to this value prior to continuing with this procedure (see Media Settings section, Programming the Label Dimensions). Follow the procedure based on the type of problem reported by the printer.

Printer is Displaying “Media Out” Message

The printer displays this message when the Black Bar Sensor sensitivity level is less than required. The Black Bar Sensor is not receiving light reflecting from the back of the label stock, indicating a label with inferior reflective qualities. Resolving this issue involves raising the Black Bar Sensor Sensitivity to a level that will allow the sensor to detect back of the label stock.
