Precautions on Paper Handling
CAUTION:
❏
Thermal paper containing Na, K, or CL ions, etc., can adversely affect the heating
elements of the thermal head. Be sure to use thermal paper that meets the paper
specifications described in Appendix A, “General Specifications.”
❏
Thermal paper starts to color at around 70
°
C {158
°
F}. Take care to protect unused
and printed thermal paper against the effects of heat, light, and humidity, which
can cause the paper to color and characters on the paper to fade.
❏
Take the roll paper out of the printer when you will not use the printer for a long time
in an environment of high temperatures and humidity.
❏ When the printer is not used for one week or more, it is recomended not to leave the thermal
paper between the platen and the print head.
