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.
