- Notes on thermal paper storage   

Since color development begins at 70°C (158°F), thermal paper should be protected   

from high temperature, humidity, and light, both before and after printing.   

1) Store paper away from high temperature and humidity.   

Do not store thermal paper near a heater or in enclosed places exposed to direct sunlight.   

2) Avoid direct light Extended exposure to direct light may cause discoloration or faded   

printing.  

Because this printer uses plated steel, the manual cutting edge may be subject to rust.   

However, this does not affect the printer performance.
