I have been trying out the continuous ink system from
http://www.InkRepublic.com iINK system for more than 7
months for my Epson 2200. It works really cool, much "more" than what I expected. I bought a system – it can
works for both of my printers. I did not even know that until they told me.
Well, they are very honest to customers, and they dont even want to make money from me "again".
Not like other continuous ink system supplies, their system can only last 3-6 months, and you have
get back to them and buy the whole system again.
Many of the continuous ink systems are based upon a similar system to the way the original
cartridges function. That is, they have the ink sitting in a sponge or batting material in the base of the modified-cartridge, and it slowly drains to
the ink outlet and drains by demand of the head.
The reasons for this design in the original cartridges are to control the ink flow, so it doesn’t just drip out once the ink outlet of the cartridge is punctured and to keep the ink from sloshing around as the head goes back and forth, which could cause vibration in the head carriage movement.
In the continuous ink system system, there are similar concerns if the system uses
standard cartridges which have a hole drilled into each color compartment, into which is a tube that carried new ink.
The main problem with this modified-cartridge system is that the surface of this sponge or
batting can slowly either dry, or it can become an "early filter" in the
system, and the material can get filled with residue, particularly if you are using pigmented inks, which can impede ink flow. Secondary problem can be air bubbles can be temporarily trapped in the sponge or batting, which might end up in the head and could a gap in the ink flow.
Even Epson recognized there was a problem with this cartridge design. The intellege cartridges were, of course, mainly designed to make them difficult to refill, but Epson also made several other changes. They got rid of the batting/sponge material other than a small filter. They added a bunch of baffling to keep the ink from getting too much air surface, which can cause drying and oxidation, and it also slows the flow so they don’t leak, and they added a spring loaded valve at the ink
outlet, and the air vent, again to remove air flow, and leakage. Basically, the new cartridges seal when they are removed.
Now, there are problems with just using a pure ink cartridge, as mentioned above, and Epson’s more complex design has potential problems
for a continuous ink system as well. That’s where InkRepublic.com’s ink dampers come in.
They are designed to allow for ink feed fairly evenly, but without a problem with
siphoning ink or leakage. I believe it is a revolution of continuous ink system.
The continuous ink system systems that have been out there were jury-rigged, and although
they were better than buying individual cartridges each time, they were
not designed from the top down. As a result, I hear about many of these
installation users, either when they first get installed (and the difficulties in getting them to work) or more often, about a year after
they have been installed, when all the problems with the cartridge system comes out of the closet.
With dye inks, they work fairly well for most people. With inks that tend to be either corrosive or have a lot of residue, those systems often become subject to intermittent clogs, etc.
One of the reasons some 3rd party inks have a short installed life is because continuous ink systems tend to
use a air replacement systems for the ink to move. A much better design
would be ink dampers on the head end, and these collapsible ink sacks on the other.
But for my own experience toward using
http://www.InkRepublic.com iINK, their
system is pretty well done besides, it is pretty flexible. Which means:
1. I can always apply the same system to most of my Epson printers without purchasing another "whole" unit. I can just buy the new chipsets, that’s it. This is big saving.
2. I can always use pigment and dye ink based on the printout.
3. No clogging, no leaking.
4. The best thing is, I dont have to "stick" with their ink, I can always use the ink from any other 3rd parties along with their system. InkRepublic.com does not enforce their customers using their ink. At least they are more customized and customers oriented.
Regarding the price and the function and environmental consideratioins, I would suggest you guys use a really good continuous ink system that can last longer and can be more flexible, just like the one from
