When you load a new roll of paper or when voids in the printout are
apparent, clean the printhead and platen roller as described next.
To clean the printhead and platen roller
1 Remove the paper from the printer. For help, see “Loading
Paper” on page 8.
PB3 Paper Compartment: Paper has been removed.
2 Clean the printhead with the included cleaning pen or with a
cotton swab moistened with isopropyl alcohol.
3 Remove buildup from the black mark sensor and tear bar with a
cotton swab moistened with isopropyl alcohol.
4 Turn the platen roller with your finger and run a dry cloth, small
brush, or cotton swab moistened with isopropyl alcohol across the
roller. Ensure that the roller is clean all the way around.
Do not use sharp objects to clean the printhead. This may
