Never throw a print head cartridge into an flame. It can explode, causing injuries.
Handling Precautions
• Make sure that nothing touches or scratches the light-sensitive print head
surface (blue colored part) or transfer roll (black colored part). Scratches, dirt, or
oil from your hands onto the print head or transfer roll will deteriorate print
quality.
• Do not expose the print head cartridge to direct sunlight and avoid exposing the
print head cartridge to fluorescent indoor light, as this may result in dropouts or
dirty printing.
