The R3000 chips are designed to reset when the two reset points are touched with a piece of metal, so I am curious if the points touched the chip sensor while removing/reinserting, and that caused the chips to reset (?). I will do some testing with our R3000 tomorrow, and am working with the cartridge manufacturer to determine why the chips seemed to automatically reset themselves when the carts were removed to check the ink levels. I have a few questions to better understand what happened, in order to help me figure out how what happened.
- Did you remove and agitate all nine carts, or just these two?
- What was the ink level showing for the LK and LLK cartridge ink levels before removing them from the printer?
- Was the printer on or off when the carts were removed and reinstalled?
Since the LK and LLK cartridges now read full, I recommend you refill them with ink so the physical ink level matches what the chip reads. Also, as per our instructions, after the printer sat unused with ink for a month- you should remove and agitate all the cartridges before doing more cleaning cycles, etc… then do several cleaning cycles or an initial fill to purge settled ink from the internal ink lines, and get correct density in-suspension ink from the shaken carts to the print head. All pigment inks settle when left sitting, which is why all Epson carts say to shake before use, and use (or replace) within 6 months. We say to shake before use, then regularly agitate to maintain suspension for consistent output results. It’s also to prevent thicker settled ink from getting drawn into the ink lines, as this could cause dampers to get filled up with particles at a faster rate, and need to be replaced sooner than normal.
How do your test prints look? Is your problem that the two carts reset automatically/prematurely, or are you having other issues with the cartridges/chips or print output?
Please let me know so I can help you sort this out.

I think I agitated both when the machine was on. I don’t remember the exact ink levels, but they were more than half empty, & no warnings had appeared about low ink levels. The LLK cart problem appeared first because it was the only one I’d taken out at that stage. The LK one was much later when I read about the need to agitate and then did it to all the carts. The other carts are fine.
I printed several A3 plus photos after the LLK issue and they appear fine, unless I’m not noticing a subtle deficiency. I haven’t done any more since the LK started reading full a bit later on in the day.
The nozzle check pattern print out seem fine, though the LLK is quite faint compared to the others, but maybe that’s just how it is.
Could it be a battery issue?
