Chapter 5 Maintenance & Adjustment
Adhesives and coatings of the media can transfer to 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 inadvertent loss of labels, label jams and possible
damage to the printer.
Note:

Make sure to turn off the printer prior to cleaning.

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.

When cleaning the print head, take care not to touch the heated portion of the print head. Print Head is
susceptible to damage from static electricity, etc. So it is strongly recommended to wear hand gloves during
cleaning progress.

Take care not to allow the print head become scratched and/or damaged in any way.
5.1 Cleaning Media Sensor
Debris or dirt on the paper sensor can cause a miss-read or unstable detection of the label gap. Clean with a
cotton bud dampened with alcohol.
5.2 Cleaning Thermal Print Head
Thermal Paper stock on the print head, which degrades print quality. Clean the print head with methanol or
isopropyl alcohol and a cotton bud. Do not touch the heating elements with your fingers.
1) Open the Printer Cover and then use the cleaning pen to clean the head in the direction from the center of
the head to two sides.
2) After cleaning the head, do not use the printer until the alcohol used for cleaning evaporates completely
(1~2 min) and the printer has completely dried.
3) Perform the cleaning process each time the paper roll is replaced to prevent print quality deterioration.
