4. Clean the platen roller when you see significant adhesive
build-up or a label is wrapped around the platen roller.
Use a dry, soft-bristle brush, such as a toothbrush, to clean
the platen roller.
If the brush does not remove all the adhesive, use isopropyl
alcohol on the platen roller. Moisten a cotton swab with
isopropyl alcohol and run the cotton swab across the platen
roller. Turn the platen roller with your finger to make sure the
platen roller is clean all the way around. After cleaning, feed
several inches of supply through without printing to remove
any remaining isopropyl alcohol.
5. Moisten a cotton swab with isopropyl alcohol. Rub the cotton
swab across the peel bar and remove any build-up.
6. Moisten another cotton swab with isopropyl alcohol. Rub the
cotton swab across the printhead and remove any build-up.
You may need to use a printhead CLEAN-STRIP if the
printhead is extremely dirty or you see streaks on the supply.
