Correct ink level status for HP 3420 ???

I have just refilled my HP 3420 black cartridge (27) and it is printing just
fine, however, upon inserting the refilled cartridge into the printer it is
still showing low ink level.
How can I get the right ink level status?
It is very important to me to have the exact information abot how much link
I have left !

Please, please help !

How could you possibly expect the printer to know how much ink you had put in
the cartridge? There are some kludgey workarounds, but there is no way you
will "have the exact information about how much ink" after refilling.
