An even easier way to Defeat The EPSON One Way Ink Valve!

Thats what i like to hear a negative into a positive, and if that way of thinking does not work you can always train them to answer phones and email while you relax

That's great in theory... I find the practical implementations tend to disagree with theory around 99.9% of the time

LOL you mean no child labour shed in the websnail house, i am disappointed

Joe, thank you for you new methode to simplyfying the modification of the one-way valve.
* Can you please convert for me the "fifty thousands diameter" in to metric?
* I also would like to know what the length is of the needle from the bend down to the blunt point.

I have two complete sets of Epson carts. One I did already modify and fill.
But later I had a problem of several carts with leaking valves.
I took these apart again and noticed that some very small matter which I could not identify, got stuck in the valve keeping it from closing.
I cleaned the valves and put them together again and the leaking was stopped.
It can be that some very small plastic parts came lose because of the action to push open the return valve and then gradually moved with the ink into the valve and then got stuck?

fifty thousandths of an inch is less than a half a millimetre, its basically needle size gauge wise.
length obviously the longer the better and id guess at least the length or height (depending how you equate things) of the cart.

The rest ill leave to joes expert hands.

No, one inch is 25.4 mm. Then fifty thousandths of an inch is 0.050 x 25.4 mm = 1.27 mm.

Here is an on-line converter for thousandths of an inch ("Thou") to millimetres.

I did it in my head and obviously did not move the decimal point opps!

@CakeHole where exactly in your head is your Decimal point located…

You wouldn't want to know , dunno how i forgot to move it in my calculations, mind you it was near 1am. The misses said good job this isn't some other forum with a different bunch of blokes measuring something else, that would had been vastly over estimating figures

The needle of whatever you choose to use has to be about 050" or about 0.5mm diameter and at least a minimum of 1 inch in length. But this is a blind process it has to be blunt tipped to prevent accidental puncturing the ink bag.
