All inkjet printers have these "waste ink pads", but Epson is the most aggressive in terms of stopping the printer when the counter is maxed out. This is made worse since they waste more ink then any other manufacturer during cleaning cycles. The printers die a lot sooner when you use such aggressive cleaning cycles which go directly into the waste ink pad. However while it is annoying, the waste ink can make a mess or damage the entire printer if you don't hard stop it when they are full. Epson printers have an internal power supply, so things can get dangerous very quickly if the waste ink overflows and it comes it contact with the power supply.
It seems like a lot of modern Epson printers (made within the past ~8-10 years) have reduced capacity waste ink pads when you compare them to older modes like the C88/+ and RXXX models, and old wide format machines. The counter limit has also been reduced to match. I have yet to find an older Epson printer (one worth using) that has a waste ink problem (LCD code, direct language or ink+paper light consistently blinking) with moderate use that ever has a waste ink issue, even after 10+ years of service and potentially plenty of printed pages. Yet these new ones with the reduced pads are known to crap out due to waste ink in 3-5 years. The days of the C88+ and machines like the R200 series (which only died due to waste ink with lots of use) went away with the wetness sensor printers (88/69/68) and were further reduced when they went to the newer chassis designs in 2010. The loss of the wetness sensor on the black cart printers hasn’t brought back the classic long life ones.
The issue is Epson is going to know you used a CIS because these printers log "non genuine" cartridge use for this exact reason. If they check, they will void the warranty even though they should be on the hook for proving it, they can get away with it by checking for that flag and charge you to replace it under warranty. These 3rd party CIS systems are not sanctioned by Epson - it’s only sanctioned in the ET series (which effectively have an internal CIS). That wouldn’t be an issue, but the repairs costs are about as much as another identical refurb. In addition, it can be quite difficult in the wide format (11x17 and larger) Epsons, as you need to partially tear the printer down to access the pads. It’s a labor and marketing scam problem.
Since the odds of Epson voiding the warranty are not in your favor, I'd suggest installing an external waste ink tank and resetting the counter. You can use a program like WIC reset utility to check the waste ink pad levels and if it's full, purchase a key to reset it but you really should bypass the internal waste ink pad first. The saturated pad should be distrusted and treated as consumed to avoid a spill. Don't attempt this if you're worried about the warranty, since Epson will see it was reset and check if you replaced the waste ink pads or bypassed them.
If you can take apart the printer and find a set of used OEM ink that you can supply with the printer if they ask, they will likely replace the printer since they won't have an easy way to void your warranty since it’s a visual passing unit. You'll also want to remove the CIS mounting clips, as these will be used against you as an easy way to prove the printer was modified in an unapproved way.
Just to show you how bad the new ones (~2010+) are, I took my old NX230 apart that I'm throwing out because of electronic burning smell problems. This is how bad some of them are now:
