7.4 Care/Handling of Media and Ribbon

Be sure to carefully review and understand the Supply Manual. Use only media and ribbons that meet
specified requirements. Use of non-specified media and ribbons may shorten the head life and result
in problems with bar code readability or print quality. All media and ribbons should be handled with
care to avoid any damage to the media, ribbons or printer. Read the guidelines in this section
carefully.
• Do not store the media or ribbon for longer than the manufacturer's recommended shelf life.
• Store media rolls on the flat end. Do not store them on the curved sides as this might flatten that side
causing erratic media advance and poor print quality.
• Store the media in plastic bags and always reseal after opening. Unprotected media can get dirty and the
extra abrasion from the dust and dirt particles will shorten the print head life.
• Store the media and ribbon in a cool, dry place. Avoid areas where they would be exposed to direct
sunlight, high temperature, high humidity, dust or gas.
• The thermal paper used for direct thermal printing must not have specifications which exceed Na
