Turning OFF the Power Press and hold the Power Button to turn off the power. CAUTION For your safety, disconnect the power plug from the power outlet if you are not using the printer for a long period of time. NOTE The printer will turn off automatically if 4 hours elapse without printing being performed. Loading the Paper Cautions Regarding Paper • Use roll paper having a φ15 inner diameter or greater (with no core) and a φ83 outer diameter or smaller. • Depending on the usage environment or paper conditions, even when using recommended paper, sticking (a phenomenon where paper sticks to the thermal printhead during printing) may occur. It may make some text unreadable or missing in print out, or result in a paper feed error. Sticking is likely to occur when coverage is high (horizontal lines, logo marks, etc.), in a low temperature environment, when printing at low speed, etc. Before printing, check the operation by using the paper that you use for actual printing, at the actual temperature and humidity levels, under the actual operating conditions. • Thermal paper does not like an environment where temperature or humidity is high. Especially when temperature reaches 60°C (140°F) or higher, discoloring begins. Take extra care when storing paper. If the temperature becomes high while paper is caught in the paper output section, the paper components may begin to melt and cause the paper to stick to the thermal printhead. • When using perforated paper, perforate it from the heat-sensitive side. Note, however, that the burr height or paper chips generated during perforating may lower the print quality or cause the printer to malfunction. Take extra care. • Do not pull paper or cover the paper output section during operation. • Use the type of roll paper whose heat-sensitive side is on the outside of the roll. 14
