    Identify the breather post and the refill port from the picture above.  The breather port should stay open before
    printing.  Plug this port if the cartridge is removed for storage.  Open the refill port only when refilling the
    cartridge.  Caution:  If this port is not sealed, ink will drain out of the cartridge.  It will take hours for the ink to
    leak out,  just seal this port after refilling the cartridge and don't worry if ink will drain while refilling the cartridge.  
    After installing the cartridge, print the solid color purge pattern for print test.  
    Limit the cleaning cycle to 2 times if you must clean the print head.  Notice the photo above there is no air
    bubbles at the bottom half.  Some air bubbles on the top is fine.  This cartridge holds about 20 ml ink, 60%
    more than the original cartridge.  The software ink monitor should not be depended on to determine how much
    ink is left in the cartridge.  But if the cartridge is refilled each time the chip reset, the cartridge should always
    have some ink in it.  Caution: It is important to fill the cartridge each time the ink monitor is showing the low ink
    warning because running the cartridge dry will introduce air bubbles into the internal passages in the cartridge
    that feeds ink into the print head.  It is difficult to remove the air bubbles unless you have experience working
    with these cartridges before.  

    Summary:
    Remove the breather plugs before printing.  The first print test should use the multi-color test pattern.
    Follow by the single color purge pattern for print test, limit the cleaning cycle to 2 times between print tests.
    Refill promptly when the low ink warning appears.  Do not run the cartridge dry.

    Chip reset:
    The auto reset chip will reset the chip after the low ink warning appears.  This reset will only take place after a
    print job is completed and the low ink warning is there.  The chip reset will be automatic if you ignorr/images/Index-1-inactive-61338.png'">
