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. 

 

7-2. Cleaning the Paper Holder and Paper Feed Section 

Remove any paper powder and dust from the paper holder and 
paper feed section with a dry or slightly damp cloth. 
 

7-3. Cleaning the Platen Roller 

Use ethyl alcohol to remove the paper powder that has accumulated 
on the surface of the platen roller.
