Printing error condition

First clean the sensor tag and sensor head open and tape. Then perform a calibration label pressing the PAUSE and FEED buttons and turn on the printer, release the keys until it starts to move the label. Wait until you are finished and ready to print.

Solution from Noel O'Kell fixed my issue. the two sensors below (ribbon and printhead)it should be clean, dont touch them, spray them with canned air. Also these couple of sensors should be as close as possible and in the best angle to be able to sense the reflection from the chromed metal piece sitting above them when the head is closed.
