Handling the BJ cartridge_______________________

• Leave the BJ cartridge in its packaging until you are ready to use it to prevent it from

drying out.

• Store BJ cartridges out of the reach of children; the ink contains isopropyl alcohol

67-63-0.

• Replace the BJ cartridge after one year of use or if the print is not clear or is missing,

even after trying five successive head cleanings.

• Never remove the BJ cartridge unless you are going to replace it. When left ex-

posed, the cartridge print head dries out, making it unusable.

• Do not touch the print head area on the

BJ cartridge. Ink may leak out and cause
stains.

• Never shake the BJ cartridge, especially

after removing the protective tape from
the print head.

If spilled, the ink is very difficult to clean. Therefore, always follow the above precau-
tions and carefully handle the BJ cartridge.
