Thermal head is hot right after printing. Wait until the head cools before 

cleaning the thermal head.

  The thermal head may be damaged if you touch it while static electricity builds 

up on your body.

to the peeling roller on the bottom of the thermal head. When the excessive 

force is applied to the roller, the roller may be deformed, resulting in 

deterioration of the printing quality.
