You are quite right that you can only refill them so many times, but I
understand that the problem is less deterioration than dried ink eventually
making the sponge material unable to take up ink or the exit port filter
less able to release ink on demand from the printer. I have the original
OEM set, nearly a year old, still working with as many as 8 or 9 refills in
some of the carts. Recently one of them started to do some banding. The
fix was really simple. First blow gently into the air vent to see if ink
drips out of the exit port. If it is not coming out easily you can turn it
upside down, put 8 to 10 drops of alcohol in the exit port, seal the exit
port with the cap that came with the OEM cart (hold on with rubber band),
turn it back upright, open the fill hole, put it into the microwave (covered
in case something unexpected happens!), together with a glass of water to
absorb most of the microwave energy, and zap it at ten second intervals
until the reservoir part of the cart reaches about 150 - 160 degrees. Then
refill and let the little bit of alchohol-diluted ink drip out of the exit
port. Apparently, heating the cart with ink in it redesolves that tiny
amount of dried ink in the sponge/filter. This is about a ten minute
project. For someone who doesn't want to bother, you can instead buy a new
OEM cart and start the process of refilling over. Some people have had
great success buying Alotofthings carts and refilling them, and your initial
investment in the cart is much less.
Yes, Measekite, I have always been a tinkerer and that is why I had a
successful career as a rocket scientist. (just kidding!) Actually, my career
involved precision work in the range of fractions of millimeters with very
small tolerances using very precise instruments. Photography, woodworking,
car repair, gardening, ceramics, wood block printing, and fishing - these
are all things I enjoy as a rest from the more cerebral and demanding
efforts that my work of 40 years involved. Dealing with inks/carts
absolutely isn't rocket science. I'm not intimidated by a $150 printer and
the simplest of tasks, refilling ink carts. It is just a no-thought-process
quick task that I can do when necessary between prints.
