Chapter 5 Printer Cleaning
Dust, foreign objects, viscous material, or other contaminants stuck in the printhead or printer may reduce
print quality. Please clean the dirty printhead as follows:
Note:
1) Be sure to turn off the printer before cleaning.
2) When printing, the printhead will become very hot. Therefore, if you want to clean the
printhead, please turn off the printer and wait 2~3 minutes before you start cleaning.
3) When cleaning the printhead, be careful not to touch its heating part to avoid damage to the
printhead due to static electricity.
4) Be careful not to scratch or damage the printhead.
5.1 Cleaning the printhead
1) Please open the top cover of the printer, and clean the printhead with a cleaning pen or a cotton
swab dipped in diluted alcohol (alcohol or isopropyl alcohol)) from its center to both sides.
2) After cleaning the printhead, do not use the printer immediately. Only use the printer until the
cleaning alcohol evaporates completely (1~2 minutes) and the printhead is completely dry.
5.2 Cleaning the sensor, rubber roller and paper path
1) Please open the top cover of the printer and remove the paper roll.
2) Wipe off dust or foreign objects with dry cotton cloth or cotton swab.
3) Soak the cotton cloth or cotton swab in medical alcohol and use it to wipe off sticky foreign objects
or other contaminants.
4) After cleaning the parts, do not use the printer immediately. Only use the printer until the alcohol
evaporates completely (1~2 minutes) and the printer is completely dry.
Note: Clean the parts when the print quality or paper checking performance degrades.
