Cleaning the Thermal Printhead
During printing, the printhead will accumulate dirt such as paper dust or
particles of ink or back coating from the ribbon. This accumulation can cause a
deterioration of the print quality. To correct or avoid this problem, the prinhead
should be cleaned at regular intervals.
Frequency of cleaning:
Direct Thermal printing:
-
at every label roll change
Thermal Transfer printing:
-
at every ribbon change
Do not use sharp objects for cleaning the printhead.
Do not touch the protective layer of the printhead with your hands.
To clean the printhead:
1. Turn the printer power off, and disconnect the power cord.
2. Raise the printhead as far as possible.
3. Remove the labels and the ribbon from the printer.
4. Clean the surface of the printhead with a cleaning pen, or use a cotton
swab dipped in isopropyl alcohol.
5. Let the printhead dry approximately 2-3 minutes before powering on and
restarting the printer.
