Chapter 5 Clean the Printer
Adhesives and coatings of the media can transfer onto the printer parts over time along the
media path including the thermal print head and media sensor. This build-up can accumulate
dust and debris. Failure to clean the print head, media path, and media sensor could result in
print quality, worst more of inadvertent loss off labels, label jams and possible damage to
the printer.
Caution:
1) Make sure to turn off the printer prior to cleaning.
2) As the print head gets hot during printing, if intending to clean the print head, turn the
printer off and wait approximately 2~3 minute before commencement.
3) When cleaning the print head, take care not to touch the heated portion of the print head,
prevent damage to print head due to static electricity, etc.
4) Take care not to allow the print head become scratched and/or damaged in any way.

completely (1~2 min) and the printer has completely dried.
5.2 Cleaning Roller or Paper Path
