Print Head Cartridge Handling Precautions
WARNING
Never throw a print head cartridge into a 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.
■When replacing the print head cartridge, work on a desk or other flat surface to avoid scratching 
the light-sensitive print head and transfer roll.
■Avoid removing the print head cartridge from the printer before it is time to replace it. Removing 
and replacing the print head cartridge can cause dirt to stick to the cartridge and deteriorate print 
quality.
■Avoid tilting or shaking the print head cartridge when removing it, as toner may spill inside the 
printer and cause damage.
■To ensure good print quality, keep the print head cartridge level when handling it.
■Only use print head cartridges recommended by Brother. Using a print head cartridge that is not 
recommended may result in lower print quality and unsatisfactory printer performance.
