Here are two of @jtoolman productions on refilling the PGI-9 cartsThis method is unknown to me. Could you please share more details about it?
If it works also on 22XX carts would be really nice. The only method I know is this one :
and it's very complicated
I red the whole thread from page one and I am very confused now on what to do.Prospective purchasers are now advised to stay away from these printers. I have ink and ICC profiles for these but yet I say stay away.
Epson has perfected the chip situation on these after 4-5 iterations. They have the upper hand, updated machines and new users are left to make sure that 2 things never occur on these machines. 1. That the optical sensor is always fooled into thinking that there is ink in the cartridge. ..blacked out optical sensor.
2. Having done 1. You must ensure that the cartridge never runs out of ink... getting ink back into the nozzles can be problematic. The only sane way to accomplish this is to use a standard capacity chip. If you use that, each reset will pull out approx 10% of the capacity of the chip by the head clean. So after changing 4 -5 cartridges or resetting them, you only get to use approx 1/2 of the capacity. ..half the ink in the cartridge ends up in the waste tank. Also explains why the waste tanks are filling fast on these machines.
If you understand the logic of how the blowout of the chips works, you'll see why its a nightmare. The only sane way to use this printer is to use Epson XL capacity OEM carts and then you're OK but you better have deep pockets. Otherwise, as far as refilling. it's now become a bad scene for the 600..810 users. I still have my XP600 with old firmware and chips but it is a different scene altogether compared to the new.
The thread started before the antics of Epson, as the thread progressed...things were changing. They have now perfected the game with this generation. Pay attention to this, I suspect this was a proving ground of how to deter after-market by Epson on future models.
