Cautions in Handling of Roll Paper
• If chemicals or oil touch the paper, it could become discolored and the printed data
could fade away.
• Do not scrape the paper with fingernails or with hard metal objects, etc. This could
cause the paper to become discolored.
• Discoloration begins from a temperature of approximately 70°C. (158°F) Be careful
of the effects of heat, moisture and light, etc. on the roll paper.
