Cleaning the Product Cleaning the Exterior After turning of the product, use a slightly damp cloth to wipe it off. Before doing so, be sure to unplug the AC cable from the power outlet. Do not use alcohol, benzine, thinner, trichloroethylene, or ketone based solvent to clean the exte- rior of the printer. Doing so may deform or damage the plastic and rubber parts. CAUTION Cleaning the Thermal Head and Platen Roller To maintain receipt printing quality, periodic (once every three months) cleaning of the thermal print head is recommended. Depending on the type of paper being used, paper dust can adhere to the platen roller and cause paper feed problems.
If this happens, clean the platen roller. Turn off the product and open the roll paper cover. Clean the thermal head and/or platen roller by wiping with a cotton swab moistened with alcohol (ethanol or isopropyl alcohol). • The thermal head may be very hot after printing. Do not touch the thermal head or components around it for cleaning immediately after printing. Wait for some time to allow the thermal print head to cool down before cleaning it. • Take care to avoid scratching the thermal print head with your fingers or hard objects.
