7. Periodic Cleaning
Print dropout might be caused by the presence of paper powder or dust. To avoid this problem, remove any black deposits of paper powder and dust from the paper holder, paper feed section, platen roller, and thermal head surfaces. This cleaning should be performed once a month, or as needed.
7-1. Cleaning the Thermal Head
Use ethyl alcohol to remove any black deposits of paper powder and dust from the thermal head surfaces.
Notes:
1.The thermal head is delicate and easily damaged. Carefully clean it with a soft cloth so that the head surfaces are not damaged.
2.Do not clean the thermal head immediately after printing because it will be very hot.
3.The discharge of static electricity during thermal head cleaning might destroy the thermal head. Carefully clean the thermal head so that it is not damaged by the discharge of static electricity.
4.Wait until the alcohol has completely evaporated before turning on the printer power.
Use ethyl alcohol to remove the paper powder that has accumulated on the surface of the platen roller.
