∙Do not set any liquid or drinks such as coffee on the printer case.
∙Do not touch any metal part to avoid possible electrostatic damage.
∙Do not touch the areas around the print head and motor during or right after printing. It can be very hot.
∙Do not allow the cut receipt to slide back into the cutter during the operation. As this would lead to multiple cutting at the lower edge of a receipt and the multiple cut thin slips tend to cause mechanical malfunction.
∙Use a grounded AC power outlet with only the power cord and power adaptor furnished with the printer.
∙Do not use a power outlet of a circuit shared with any equipment that uses a lot of power or causes great electrical noises, such as a copier, electric motors or a coffee maker.
∙Do not use thermal paper containing Sodium (Na+), Potassium (K+) and Chlorine
∙If the surface of thermal paper is scratched with a hard object such as a nail, the paper may become discolored.
∙If thermal paper touches diazzo copy paper immediately after copying, the printed surface may be discolored.
∙Use only water paste, starch paste, polyvinyl paste or CMC paste when gluing thermal paper.
∙If thermal paper touches anything containing phthalic acid ester plasticizer for a long time, the image formation ability may be reduced or the printed image may fade.
∙Use of volatile organic solvents such as alcohol, ester and ketone or some adhesive tapes on thermal paper can cause discoloration.
∙Thermal paper must not be stored with the printed surfaces against each other as the printing may be transferred between the surfaces.
∙Since the paper roll is highly thermal sensitive, please keep them in a dark place that is 20º and 65% RH when not installed in the printer. Avoid extended exposure to direct light. Use only products made from polyethylene, polypropylene or polyester for storage of thermal paper.
