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. While pressing the cover release buttons on both sides, open the top cover.
3. If immediately after printing, leave the printer for several minutes until the thermal
head cools down.
4. Use a cotton swab dipped in ethyl alcohol to wipe the heating surfaces and paper feed
rollers of the thermal heads clean of paper dust, etc.
CAUTION
 The thermal head is hot immediately after printing. Be careful not to touch it with your hands.
 Do not touch the heating surfaces of the thermal head with bare hands or allow metals to
come into contact with it.
