... but there's still plenty of room for money-making racket unless you get one with a user-emptyable waste ink tank. (end of advice)
My ET-14000 apparently has 11 ink-absorbent pads in the base which are fed ink used when cleaning the jets. The printer kept track of how much ink was pumped away and then refused to do anything until it was emptied. I found the service manual and to reach the pads I would have had to disassemble the entire printer, including all sorts of tape and instructions as to how many Newtons tight each screw should be. Oh, and if I got Epson to do it, that wouldn't be done under warranty because I had used all sorts of non-Epson inks. Day-glo and invisible UV ink is cool!
Anyways, I got a 'printer potty' which is an external waste ink tank, and a fairly reasonable product: of course I could have made my own, but they had done all my homework for me (including telling me which way the ink flows, which is not obvious, and would have been very messy if I'd done it backwards).
Then here comes the racket: To reset the waste ink counter, which can only be done by special Epson software, I can instead pay €10 per reset per serial number to some clever Ukrainians who have reverse-engineered all that Epson software.
Fortunately I was able to pirate the Epson software and do it myself, but ... sheesh!
The fun part is I'm going to filter all of my waste ink back into the black tanks and then watercolor over wet prints, expecting some neat results there.
Still arguably better than the ink cartridge thing though, I guess.
Pretty cool what custom ink stuff you can do with it!
I really need to set up an auto job that just prints a test page once a week to save ink on cleaning. But I still haven't had to buy more ink after a purchase over a year ago, even with all that cleaning I've had it do.
As for fading, one sheet that's been outdoors for two years has faded about 75%, but nothing not exposed to bright sunlight has.
Runs OK on Linux over WiFi. Used to also work on USB, but that stopped working reliably at Ubuntu 20.04 LTS. Also, on WiFi it phones home and tries to download firmware updates.
So I ended up with lots of ink in the trash in the end.
