Refilling OEM EPSON carts. A newer method.

[jtoolman]

This method will not require any holes or other hardware to be installed and these are not external physical modifications required.

Already did about 12 empties of various model numbers.

This method is applicable for the following CARTS:
T0691, T0692, T0693, T0694
T0711, T0711H, T0712, T0713, T0714
T0731, T0732, T0733, T0734
T0771, T0772, T0773, T0774, T0775, T0776
T0781, T0782, T0783, T0784, T0785, T0786
T0791, T0792, T0793, T0794, T0795, T0796
T0891, T0892, T0893, T0894
T0801, T0802, T0803, T0804, T0805, T0806
T0811, T0812, T0813, T0814, T0815, T0816
T0821, T0822, T0823, T0824, T0825, T0826
T0870, T0871, T0872, T0873, T0874, T0875, T0876, T0877, T0878, T0879
T0881, T0882, T0883, T0884
T0961, T0962, T0963, T0964, T0965, T0966, T0967, T0968, T0969
T0971
T0981, T0982, T0983, T0984, T0985, T0986
T0991, T0992, T0993, T0994, T0995, T0996
T1001, T1002, T1003, T1004
T1241, T1242, T1243, T1244
T1251, T1252, T1253, T1254
T1261, T1262, T1263, T1264
T1271, T1272, T1273, T1274
T1281, T1282, T1283, T1284
T1291, T1292, T1293, T1294

I also believe that is will work on some older cart models as well.

The resetters for some of the aboe models are here:

I am also using a pair of EPSON resetters that can reset my R1900 R2400 R2880 1400 2200 R380 R340

Very instructive, thank you!

One thing I didn't understand yet: On the first cartridge you "ruptured" the membrane chamber with air. On the second cart you are using a syringe filled with water.
So do you have to
- FIRST rupture the membrane only with air and
- SECONDLY fill it up with ink?

And is there no damage of ink flow of the refilled cart because of the ruptured membrane chamber?

An old cartridge that I messed around with a few years ago.

Behind the cutaway used to be a very fine filter material like cloth that basically filters the air that comes through the bottom of the cartridge. This is the hole that the ink leaks out from when you refill the cartridge.

What happens when the ink wets this filter material? will it dry out and clog the filter and lock up the cartridge or will it remain moist?. With pigment ink, the resin I imagine will cake up and harden the filter and then act the same as if the filter breathers on CISS tanks are wetted with ink. They stop breathing.

Have you tested for this aspect to confirm that it does not matter?

If you look hard enough you'll see the outline of the filter box on the other side.

Just like the previous generation, there are a series of lateral passages that go from side to side. On the prior generation, Epson realized that there was a weakness in their baffle design that allow easy refilling. They subsequently changed the interior baffle angles to fix this. On the exterior all was the same. It would be truly interesting to see if Epson has been beat considering the intricate angles and baffle designs they've put in.

OK. Look carefully at the above cartridge. You'll see four colors.

Black Area. On the standard capacity cartridges this area is blocked off and sealed. It is dead volume. On the extra capacity it is opened up for more volume.

Yellow and Orange area is where the ink normally resides.

Red area is where there is not supposed to be ink. There can be traces there but only very little and minute amounts. This chamber goes up, heads into the other side with a tiny hole and then enters a labyrinth on the other side that eventually leads into the filter box. From the filter box, it exits, hits the plastic label and is diverted with another lateral hole into the exit/air entry port. Those grooves on the other side are there like the grooves in labyrinth on the Canon cartridge. If they get blocked up they can possibly lock up the cartridge.

I make a distinction in the orange area because I will ask if this area is empty or filled with ink. Here's why. Based on what I see, the red area can hold ink but is not supposed to. The orange area is a dead corner that holds ink. If air is trapped in there, the red area volume will have ink and still achieve the total weight, but there should be no ink entering the filter box. How do you get ink into this area where there is only one tiny hole leading up to it? A similar trick was in the prior generation cartridges where the bottom half of the cartridge emptied first before the top half.

I have not been able to check but when I investigated these cartridges I only saw problems for the average user and killed the idea. Maybe, you've made a breakthrough.

The place where Epson originally fills these cartridges appear to be a matrix about 1/2" x3/8" cutout behind the exit nozzle on the skinny underside. That appears to provide access to all compartments.

Now these carts that jtoolman have shown are very very different from these.

It is as if Epson has reversed course on these printers and decided to allow refilling the OEM carts. Like the older Canons.
