6. Cleaning Head

Printing quality might be degraded by dust, foreign substance, adhesive substance, or other
pollution materials stuck in the printer head or inside the printer.
When dirty, clean the print head as follows:
※ CAUTION
- Make sure to turn the printer power off prior to cleaning.
- As the print head gets very hot during printing, if intending to clean the print head,
turn the printer power off and wait approximately 2~3 minute before commencement.
- When cleaning the print head, take care not to touch the heated portion of the print
head.
→ Printer Head is susceptible to damage from static electricity, etc.
- Take care not to allow the print head to become scratched and/or damaged in any way.
- Be careful not to get your fingers pinched when opening or closing the paper cover. Also
be careful the paper cover does not slip off and drop.
- When loading roll paper, be careful not to get your fingers pinched between the paper
roll and the supply unit.
- Do not touch the cutter with your hands. Doing so could result in an injury.
