This problem may occur if the RD Roll was not installed correctly.
Please follow the instructions below:

1. Press and hold the Power button to turn the printer off.

2. Open the media guides by lifting up the media guide adjustment lever (1) and pulling the media guides outwards.
   
3. Insert the RD Roll so that the labels feed with the side to be printed on facing up (1), as shown.
   
   • Use RD Rolls with an outer roll dimension of 5" (127 mm) or less.
     Use RD Rolls designed for TD series printers. Regardless of the size, some RD Rolls may not be usable.
   • Insert the RD Roll facing the correct direction. If the RD Roll is not inserted correctly, the printer will not print on the correct side of the paper or label.
