Jon,

Is it possible to reuse the K7 carts from Inkjetmall by refilling from the bottom, then using a 
chip resetter?

Harry

All K7 cartridges are designed for refilling. The usual method is to
use a syringe and the vacuum method through the small silicon plug on
the top of the cartridge through which we initially fill the cart.

Temporarily tape over the vent hole. Fill a clean syringe with about
15ml of ink, insert it into the cart, draw out a vacuum, replace the
vacuum with the contents of the syringe. It may take more than one
attempt due to the introduction of foamy ink. But, if you draw your
vacuum slowly through the ink in the syringe, or invert the cart so it
does not draw through the ink, you should be able to replace the
vacuum without introducing foam.  Any foam will go away with an hour
anyway. Then reset the chip, remove the tape and away you go.

Most of our carts hold 21ml ink, but EPSON chip readers in their
printers will not allow more than the use of about 14ml. So you should
be refilling a cartridge which still has some ink contents. This
unfortunately is normal.

Jon,

Would your empty 220ml carts be useful as cleaning/flusing carts to 
use with your cleaning fluids?

The procedure to refill those is a bit different than the smaller 
carts, but still the same basicn principle.  I have some adapters to 
use with a syringe to first fill them with water to clean them out, 
then to refill them.

There would probably be a little bit of remaining ink, but mostly 
flush fluid.  Any limitations to using the carts to flush with any 
specific pre-existing ink sets - Ultrachrome, dyes, etc?  

I think you are 100% on the right track with your focus on the 
ecological impact of the use of pre-filled carts from Epson, etc.  

I have 2 sets of 220ml refillable carts for my 2 Epson 7600's.  I am 
planning to migrate one of the 7600's to the Cone Color inks. I will 
probably substitute the neutral K7 blacks as mentioned in another 
thread (instead of the greenish Epson match ones), as I have to 
create new profiles anyway.  I do have an i1 spectrophotometer.

Guess I'll have to wait a bit for a Vivid Magenta match for my 
7880? ;>)

Thanks!

Best,
Michael

Michael,

I would think that you should flush them first with distilled rather
than tap so you do not introduce material that ends up clogging your
dampers. My country water for example, could never be used. It has way
too much mineral content in it.

But it sounds like your plan will work well.

Thank you Jon!

I am glad I asked. Sometimes the questions seem obvious, but I would 
not have used distilled water.  Good point!  We are on a well, lots of 
iron, etc.

Thank you for sharing here.

Best,
Michael

Thanks, Jon.
