[barfl2]

Barfl2 pleased to advise now been sucessfull with the German method now I have some Octoinkjet squeeze bottles which have much smaller needles than my previous attempts with syringes. the needle slides nicely along the bottom of the cart. Thanks for all the good advice.

Happy refilling to those using the German Durchstich refill method in 2011 !!!

I bought an iP4700 a couple of months ago, just as it was disappearing from the shelves, and got the Image Specialists ink and resetter from OctoInkjet for the day when the OEM inks ran out. That day was today! All went quite smoothly, I had low warnings on cyan and magenta, but decided to refill all 5 cartridges and seemed to use about 6ml or so to top up all the cartridges. The cartridges are all back to their original weights (20gm & 35gm), so I'm sure I've got them properly refilled, and the reset tool was simplicity itself to use. Colours on a quick print and the nozzle check look fine.

The only problem I had was in getting the needles to find the gap in the inner wall to the ink chamber, they invariably went somewhere else out of sight and hit the wall so I had to withdraw and try again about 10 times before finding the gap. My needles are pretty flexible though, they're 2 3/4" 0.8mm ones I bought years ago for an HP. Are there any tips for avoiding this?

To get the needle in straight I just try and keep a little pressure on the needle so it stays flat across the bottom of the cartridge. This seems to work well for me.

Maybe it is a lame advice, but if you use beveled needles, take the bevel direction into account. The needle will bend slightly its path following this direction. So, if you introduce the needle into the cartridge (or twist it inside) with the tip facing down, it will tilt downwards.

I use aftermarket cartridges and play this trick to guide the needle.

hey... my ink arrived today and i think i'll start refilling in less than a week now, wainting to run out of ink... wish me good luck))

p.s. are there any problems with a 20g blunt needle when passing through the sponge?

None, just take your time and feel your way as you find the best path.

Why durchstich?

Why on earth do you puncture the cartridge on the other side and stick that long needle all the way through? Why not just puncture it on the near side, right where you inject the ink?

For that matter, has anyone tried the InkTec kit? The advantage of that is you don't puncture the cartridge (I guess the system is different for different printers, though). (I can't post a link, but you can see it at the inkjetcartridge Web site and click on HP564, then scroll to the bottom.) Wondering if people have tried it.

We puncture it on the sponge side so that we don't have to re-seal the hole or deal with leakage.

 

[ThrillaMozilla]

Amazing! But let me see if I understand this. You puncture it near the bottom, then fill the adjacent chamber full, ABOVE the level of the hole? And it still doesn't leak? Or dry out?

And why is it necessary to puncture it at all?
