Cleaning the Thermal Print Head
Attention
You must wait a minimum of 5 minutes before cleaning the thermal head to avoid severe burn injuries. Never use
water to clean the thermal head. You should only clean the print head if you are instructed to do so by technical
support.
Clean the thermal head if print quality has decreased and/ or you see hard lines in the middle of prints. Always clean the
platen roller first.

Release the open lever and open the front cover.
2.
Remove the ribbon tray and set it aside.
