MAINTENANCE AND TROUBLESHOOTING

4.1 Periodic Cleaning

A dirty print head or platen may reduce printing quality or cause malfunctions.
Also, if paper dust collects on the sensor's protective sheet, paper cannot be
detected correctly. We recommend cleaning the printer periodically (every 2 to
3 months) as shown below.
1. Turn off the power.
2. Press up on the cover open button to open the paper cover.
3. Wait a few minutes until the print head cools.
4. Use a cotton swab dampened with ethyl alcohol to wipe off any dirt and dust that is
on the print head and platen.
5. Use a cotton swab dampened with a little water to wipe off the sensor's protective
sheet.
Make sure there are no water drops on the cotton swab before wiping.
Print head
CAUTION
 The print head is hot immediately after printing. Do not touch it.
 Do not touch the print head with bare hands or metal objects.
 Do not use alcohol or cleansers to clean the surface of the sensor's protective sheet.
Doing so may fog the sensor's protective sheet.
 Paper scraps may stick to the platen when adhesive labels are full cut depending on
the printer's environment, the diameter of the paper roll, and the quality of the label
backing.
