4.1 Cleaning the Print Head
If the following cases occur, the print head should be cleaned:
• Printout is not clear.
• Paper feeds and retracts with excessive noise.
• Debris on the print head.
The following steps are for print head cleaning:
1. Turn off the power and open the top cover.
2. Wait for the print head to cool down completely.
3. Wipe off dust or particles on the surface of the print head with a soft cotton cloth
dampened with 70% isopropyl alcohol. (It should not be dripping.)
4. Wait for 5 to 10 minutes until the alcohol evaporates completely. Press down the
print head module and close the top cover.
Caution:
Do not touch the print head during printing and just after operation. It is a thermal element
and can reach a high temperature. Contact with the print head can cause a minor burn.
Important:
Do not touch the print head. It is an ESD-sensitive device. Contact with the print head
may cause damage.
