B.3 Notes On Paper Handling
B.3.1 Notes on Thermal Paper Handling
Substances such as chemicals on thermal paper may cause color development or faded printing; therefore, pay attention to the following:
❏Use water paste, starch paste, polyvinyl paste, or CMC paste when gluing thermal paper.
❏Volatile organic solvents such as alcohol, ester, and ketone can cause discoloration.
❏Some discoloration may occur, depending on adhesive materials. Printing may be faded, depending on materials of tapes.
❏If thermal paper touches anything that includes phthalic acid ester plasticizer for a long time, it can reduce the
❏If thermal paper touches diazo copy paper immediately after copying, the printed surface may be discolored.
❏Thermal paper must not be stored with the printed surfaces against each other because the printing may be transferred between surfaces.
❏If the surface of thermal paper is scratched with a nail or hard metal object, the paper may become discolored.
B.3.2 Notes on Storage
Since discoloration begins at 70 °C {158 °F}, thermal paper should be protected from high temperatures, humidity, and light, both before and after printing.
❏Store paper away from high temperatures and humidity.
Do not store thermal paper near a heater or in enclosed places exposed to direct sunlight.
❏Avoid direct light.
❏Extended exposure to direct light (as with placement of the printer near windows) may cause discoloration or faded printing.
❏When the printer is not used for one week or more, it is recommended not to leave the thermal paper between the platen and the print head.
