4. MAINTENANCE AND TROUBLESHOOTING
4.1 Periodic Cleaning
Printing may not be performed normally if the thermal head, paper feed roller (platen
roller), or sensor protection sheet are dirty, so cleaning should be performed regularly
(every two or three months).
1. Turn off the power.
2. Flip up the cover open lever 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.
CAUTION
 When opening the paper cover, be careful not to touch the entrance of the blade of the auto
cutter.
 The print head is very hot immediately after printing. Be careful not to touch it with your
hands.
 Do not touch the print head with bare hands or metal objects.
