when you see voids or streaking in the print
as shown.
When you are using higher speeds (with 203
or 300 dpi), and/or increased print contrast,
we recommend cleaning the printhead after
each ribbon with isopropyl alcohol. If you still
notice build-up on the printhead or black
streaks on your supply, use the enclosed
printhead CLEAN-STRIP.
You may have to clean the supply sensor more
often if you frequently receive supply error codes.
1. Turn off the printer and open the cover and
printhead assembly.
2. Remove the label roll and ribbon (when cleaning the
printhead).
3. Press down on the exit cover tabs to open the exit cover on
the front of the printer.
4. Clean the platen roller with a dry cloth or small brush.
However, if there is adhesive gum build-up on the platen
roller, moisten a cotton swab with isopropyl alcohol. Turn the
platen roller with your finger and run the cotton swab or dry
cloth across it. Make sure the platen roller is clean all the
way around.
