Getting Fingers Dirty

As U know this is the C67 yellow original cartridge
The ink was still there....it didn't flow of....
and it was not a magic....
Mmmhhh...how could it be...???
It's simple, rip off your c67,c87 cartridge cover on the side that
look it was able to pull of or at side which is stick to the bigger
part of cartridge ( the wide white part which doesn't contain any
sticker or text )...then you'll find a black film....rip it off also
slowly...remember slowly...( i started from upper left on my cartridge
here ) then you'll find the magic...
As u know the shorter blue was the filling hole, i cover it with bolt
then i hot glue it
The longer blue pointer was the air valve
The green pointer was the ink flow through several chamber
The red show us the vicious ink valve, well there must be an ink inside it,
or it won't work ( i got my black and magenta cartidge dead coz of this )
So this transparent cartridge was very easy to refill..
but watch out for the air bubble...when u refill it....
u can eliminate or remove or move the bubble by slowly massaging the
plastic transparent side so the bubble will move to the refilling chamber
i found that shaking the cartridge was decreasing the bubble size so it's
easier to move between chamber...
BTW : Sorry it's blurry
