The dirt on the tape feed roller may cause slipping of the paper.
Clean the roller with a cleaning sheet following the steps below:

1. Turn off the printer.


2. Hold the DK Roll compartment cover at the front of the printer and firmly lift it up.
   


3. Remove the DK Roll.
   


4. Remove the backing paper (2) and insert the edge (1) of the cleaning sheet into the printing unit until the area pointed with the arrow in the diagram below.
   
   • Insert the sheet without removing the part (1).
   • Check that the printing surface of the cleaning sheet is upward.

    

5. Close the DK Roll compartment cover and press the ON/OFF button to turn the printer on.
    
6. Press the Feed button for more than one second. The roller spins by 4" (10 cm). The adhesive face of cleaning sheet removes the stain or dust on the roller.
   
   • If not pressing the Feed button for more than one second, the roller spins only 1/3" (8 mm).
   • Dispose the cleaning sheet after use.


7. Open the DK cover.

   • Make sure that the spool arms are inserted firmly in the spool guides on the left and right.
   • Insert the spool with the DK Roll located on the right side of the printer.
