costco refill ink cartridge service

Another clarification.

Almost all Epson printers currently on the market use separate ink
cartridges. None of these (at least OEM units) have "foam" inside. A
few of the ganged cartridges which have a series of color chambers in
one cartridge still have foam or batting in them, and many older Epson
models going back about 3 or 4 generations had foam or batting within
the cartridge.

The price of $7-9 for the 1.5 oz. of ink in the #45 is not too bad
when somebody else is doing the refill. Ink can cost up to $4/oz. I
buy cheaper bulk ink myself. I wish I had one of those ink fill
adapters. I have my own system. When I remove the fill ball at the
bottom, I tap the hole and taper the edge. Then I close it up with a
tapered machine screw. I have used hot melt glue, but this screw is
the surest leak free method for me. My method takes a little time, but
I use those carts for so many repeat fills that it still pays.
PS. 21ml is nowhere close to 45g.

Are you sure it would cost around $4 to refill ourselves. I don't count
but I paid around $20-25 (don't remember) for 6 bottles of ink for my Epson
RX680, and I have refilled somewhere around more/less 10 times and most of
them still have around 1/2 left, and the Yellow has around 1/3 left, the
Light M has around 2/5 left.

And I am using the clear refillable ink catridges without foam inside.

Ohhh.. I think you mean $4 per OZ of ink *not* $4 per refill. I think you
are right.

And *if* you use the refillable ink cartridge then it's much easier to
refill, and you don't need to take your time as the old needle method. Cuz.

- The refillable ink catridge is a special clear ink cartridge with no foam
inside. Or you can see think ink level inside.

- The catridge has 2 holes and comes with PLUG

- All you need to do is

a. getting ink in the syringe (no needle)

b. Push the end of syringe into one hole firmly

c. Instead of pumping ink into the cartridge you PULL the flunger to
create VACUMM, lets go of the flunger and the vacumm inside the
catridge will suck the ink in equal the air being sucked out. And you
can use the catridge right away without having to wait, and there should
be no bubble issue. Or no cleaning needed
The subject cartridge is the standard HP#45. It uses a foil bag and
there isn't any foam. When refilled with a snap and fill refilling
adapter no holes or needles are required. A syringe is attached to the
adapter which fits over the print head nozzles and is used to suck out
all of the air from the foil bag. Then the syringe is filled with ink
and then re-connected to the adapter to inject the ink thru the print
head nozzles. An extraction of a small amount of ink at the end of the
refill process is what creates the vacuum. It cost $0.67 per fluid ounce
which is $2.13 for a 42cc HP #45 cartridge.

It sounds like HP has different design than Epson which has foam inside,
and after 3-4 fills the ink probably dry out inside the cartridge so you
will get much fewer print. And most people replace the catridge with a
newer one after 2-3 refills.
