Periodic Maintenance
The printer does not require any routine maintenance. However, reasonable care of the printer will extend its
life. The following periodic measures are recommended:
• Cleaning the unit is the most important action the user can perform.
The frequency of cleaning is dependent upon the environment.
– Turn the power OFF.
– Clean the case and covers with a soft cloth. Use any mild commercial cleaner on the cloth, do not spray
directly on the printer.
– Remove the top and the smoked plastic covers. Vacuum or dust the inside area of the unit. Be very
careful not to damage the flex ribbon cable and the carriage drive belt.
– The platen should be cleaned with denatured alcohol only.
– The carriage guide bar can be lubricated with a very light oil. Contact your Authorized Panasonic
Service Center for advice on lubrication.
Ribbon Cassette
A single ribbon cassette permits the printing of about 3 million characters. When the printing starts to fade,
gently push the counter spring in the re-ink hole (A) with the tip of a ballpoint pen or other object. Once the
ribbon cassette is mounted onto the carriage and printing is performed for a short time, the characters will
become darker.
A
Note
• Do not re-ink the ribbon cassette before printing starts to fade. If the ribbon has too much ink, the
characters may smear when printed.
• Wear and tear of the printhead pins may cause serious damage to the ribbon cassette and cause the
printing to fade. In such cases the printer needs servicing.
