Platen Rollers
Occasionally, you will need to replace the printhead platen rollers. After
prolonged use, one or more rollers may develop flat areas, which will affect
print quality.
TO REMOVE AND REPLACE THE PLATEN ROLLERS ON STANDARD
PRINTHEADS:
1. Turn the printer off and unplug it.
2. Flip the printhead cam up to open and lock them open.
3. Remove any label stock that may be positioned over the platen roller(s).
4. Release (unlock) the printhead cam(s) but do not lock. Press down the
silver clip holding the printhead cam(s) and pull the cam(s) completely out.
5. Lift and hold the printhead assembly or assemblies completely up to the
right. With the platen roller now easily accessible, lift it up and out.
6. Gently place the new roller in position. Do not force the roller. Difficult
removal or replacement can occur if the roller is held at an angle. To avoid
this, lift rollers straight out or drop straight in.
7. Lower the printhead assembly or assemblies.
8. Reinsert the printhead cam and lock closed.
9. Reinstall label media and thermal transfer ribbon as required.
10. Close the printhead and turn the printer On again.
