Great job,pharmacist!One caveat:if you are using empty catridges that are dried out,it would be advisable to purge(flush out all old remaining ink) before refilling.This requires drilling a hole on the reservoir's top(which can be sealed with a screw or hot glue,etc.).The the Durchstich method can be used for future refills as described above,without unsealing(no need to remove screw,hot glue,etc. from reservoir).
Hi Avolanche: actually I'm now combining both the german Durchstich method with the plugs I've got from Hobbicolors, just in case I need to flush the sponge. But on Druckerchannel.de they claim this method also works great when the sponge is already completey dried out: in this case one must take out the needle from the cart and put it upside so the ink compartment is facing upwards, then wait for 2 minutes or so and refill again until full.
The only cartridge which might have a problem sooner is the BCI-3eBk or the PGI-5Bk black pigmented ink cartridges, since those are more likely to get problems from precipitated pigment inside the sponge, especially when you let the ink dry out inside the sponge. I think you have to flush the cartridge after every 5-6 refills to get a flawless ink flow. The dye ink cartridges need a flush only sporadically.
I agree completely.I just flushed 4 PGI-5(pigment black) cartridges that had dried out-got 'em off Ebay.There were many small pieces(granules) of dried ink that I saw in the purged water.
I'd certainly test a dried,then refilled cartridge before I used it(to make absolutely sure that the new ink,in fact,dissolved these dried chunks).Otherwise,particles could clog the head.It's possible that the refill ink will dissolve these pieces(or that the foam traps them from getting into the head),but I'd want to be sure first!It's not worth a clogged head to me.
Thank you for this guide, do you have maybe an online link or anyone else to purchase the right size needle and syringe though (Like Amazon or Ebay, Ink refiller retailers)? My local pharmacy doesn't carry them. Thanks again.
Beetlenut shared that he used a pushpin to make the hole to inject the ink.
I have used his method and think it works great.
Just push the pushpin to make the hole, then as you withdraw it, rotate it in a circular motion to expand the size of the hole at the point of entry. This allows the innermost edge of the hole to fit snugly around the needle as it is inserted.
Beetlenut had posted 2 places to buy the right size needles
in his post at http://www.nifty-stuff.com/forum/viewtopic.php?pid=14666#p14666
I think I measured that the minimum length should be 2 inches (measuring just the metal shaft of the needle), which is equivalent to
approx 50 mm.
Of course it's ok to be longer (I used 3.5" approx = 90 mm needle).
But 2 inches (50 mm) seemed like an ideal length to just reach into the reservoir chamber.
On the issue of making a hole for purging (when needed), when one has been using the German Method,
I was wondering if it made more sense to make the purge hole over the sponge chamger,
instead of over the ink reservoir....
perhaps at the "Hole to nowhere?"
Any ideas whether this would be better than over the reservoir? or not?
Thank you for the links and information.
