Refill Epson OEM Carts

[jtoolman]

Here is the URL for Rjettek Epson Refill kit. Either Kit will provide you with the special tip. I do not think you can buy it individually.

And by the way this will ONLY work with the older carts that have two taped over holes on the underside next to the exit port. It will not work with ANY newer carts.
SO if you have an older SP2000 / 1800 or R24000, you can use this kit to refill the original OEM carts. And as you know, nothing outperforms OEM carts.

Here is my Video on how to use this Kit.

Hi Joe,

Thanks for the picture. The only problem is the resetter: some chips might not be able to be reset. I think technically refilling is not a problem. The greatest problem will be resetting all chips. Most likely one or two chips will be the culprit of this approach.

Joe: the rubber tip that you use tightly closes off the complete opening around the exit nozzle and enables using pressure to push ink in the Mylar bag.
Most likely it is also this pressure which pushes open the plunger?
The rubber tip can in my view not push open the plunger.

Summarizing: without the possibility to close off the complete vicinity around the exit nozzle, which the rubber tip does perfectly, no pressure can be exerted, the plunger does not open and ink will just flow out of the exit nozzle.

I also doubt that the Octopus metal refiller which The Hat pointed at, can be used?

When inserted in the valve it might close off the extremely small opening in the rubber seal that sits directly above the plunger.
I doubt whether the tip of the metal refiller will be fine enough to go though the small opening in the rubber seal to open the plunger.
But even if it is fine enough to open the plunger, one can still not exert pressure without have ink flowing out of the exit nozzle.

When using a syringe with a needle, the plunger can be pushed open, but when exerting some pressure to push ink in the Mylar bag, ink will flow out of the exit nozzle in all directions.
It seems to me that your rubber tip is absolutely key in the technique you developed.

It's not rubber. It is black styrene and quite stiff.

No I got it in the USA from Rjettek as part of a refilling kit for Older Epson Carts such as those used on the SP2200 R2400.
By the way, just about an hour ago I did a short video demonstrating how one can use a normal syringe to fill Modified OEM 3800/3880 carts.

I also just got a response by a user who seems to able to use this resetter.

I just ordered one and will report on it after it arrives next week Thursday.

OK I use both refillers that I posted in #2 and they work perfectly 100% 0f the time now you can buy the green type if you wish or make your own as I did, the 3880 carts are very much the same as Pro 1 cart are except for the plastic membrane.

I also doubt that the Octopus metal refiller which The Hat pointed at, can be used?

I only posted the HP refiller to show the side holes in it and I didn’t intend to suggest that it would actually work in your 3880 cart, sorry.

Take 5 minutes out and pull a part a 18 gauge syringe or smaller, trim the sides around the tip and then try it yourself, it will cost you nothing and you’ll learn more than you think because you’ll than have practical refilling experience rather than theory, just remember to pierce the plastic membrane before attempting the first refill.

Happy Refilling..

Thank you for your advise.
Esp. constructing a refiller from a needle could be a good idea!

OK Guys, I just got back from the person that used the resetter from ebay.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=181401461962#ht_2927wt_783

He has been able to reset ALL his chips. I will have one of that version by Thursday and will test it.

Harry, so if that solves that then all you need is to sort out the refilling with either the regular syringe like I show on the video https://www.youtube.com/watch?v=qpkEN2ER40A or with a modified 18 gauge needle ( without the needled ) or by simply filing away a little notch on the tip of a regular syringe. I think that option will be a lot sturdier for repetitious uses.

The Question is: can you refill Epson Pro 38x0 cartridges without the valve modifcation, BUT with this special refill tip, with side flow holes? I can't make this up. seeing the video. Joe, can you enlighten me ?

Hi Harry,
This refiller may work but we don’t know so you’ll be the first to try it out if you get one, here’s the address:- http://www.octopus-office.de/en/sho...gelventil-refill-hpR-932-950-970-aus-messing/

The Question is: can you refill Epson Pro 38x0 cartridges without the valve modifcation, BUT with this special refill tip, with side flow holes?

The modification will still have to be done to the inlet of the 3880 cart before any refilling is possible..

Though it's hard to see in the photo of the syringe, it is simply a tip that has been contoured to fit the exit holes/valves of older Epson carts. The only thing that is significant is that it has a groove across the circular edge of the tip so the un grooved sections push the poppet valve and you can still shoot ink through the side groove into the cart.

Now whether one can inject ink into the UNMODIFIED carts? I have not been able to do so regardless of what trickery I use. The little round mylar flapper valve defeats all attempts. Regardless of what tip you use.

You would have to pass a tip around the poppet valve and then the most difficult part would be to get it past the poppet spring without damaging it! Then even IF you could do that you are still presented with the Rear cap which is attached to the valve body by two snap dimples. There is not direct line between the you and the flapper. It is protected. The flapper valve lives inside, between the rear cap and the valve body and sits in a matching circular recess with about 3-4 thou clearance up or down.
It's trying to shoot a bullet where it would have to make several turns around two obstacles before hitting the target.

That little flapper seals a small orifice in the rear cap. Clearance between the rear cap and valve body has to be a few thou. The flapper lifts off the orifice leading to the ink bag's content, when outside negative pressure is present as in when the printer requires ink. Also remember that the carts are also pressurized. Why doesn't the cart simply empty out into the printer? Because there is still another one way valve per color built into the printer. Where? I have no clue and the service manual does not indicate where that might be located.

Now IF you attempt to inject ink into the cart, as soon as you exert ANY positive pressure through the exit port, the little flapper immediately seals the rear orifice leading to the bag. No GO

It is a very simple yet amazingly efficient bit of technology. When I dissected a cart to see how it was put together, I had to laugh.

I cut the ink bag away from the valve body and again tried to inject water into the valve, again it was a No GO.

I then carefully popped off the rear cap and put it back on and WOW, all of a sudden I could inject water through it!!!! WHAT HAPPENED!!!!

I had unknowingly let the little almost invisible flapper disk/valve fall on the floor. I had no clue that had taken place.
SO of course without the flapper valve's presence, the one way system was now eliminated.

So I performed another necropsy on yet another cart and this time took my time to see what was actually inside between the rear cap and the valve body and that's when I saw it. Tiny circle od clear plastic about 3mm diameter.

So when you either do my original method, you are physically drilling a little hole through the disk there fore creating a passage for ink to pass into the bag. That takes a bit of skill and time to do correctly. You could end up with the drilled ink bag!

With the EASY method, after removing the seal, poppet, and spring, you insert a BLUNT needle into the valve neck and dislodge one of the sides of the rear cap.
It is a bind operation so you must listen and feel for the small "POP" as on of the dimples is dislodged.

Now you have a un protected fill hole.

The flapper disk is floating inside the bag. It can not interfere as it is simply too big to even block the valve body opening.

I have been flawlessly printing now HUNDREDS of larger prints without a single ink flow or ink monitoring related problem! That is the proof of the pudding as they say.
