Why doesn't my printer work

The first thing I always check on these Epsons is for waste ink errors, just to make sure it isn't that issue. Since the pad is internal on this one and isn't considered "user serviceable," it throws a similar error when saturated but usually flashes the ink and paper lights rather than the power button+ink and paper lights on US/CAN models (unsure if the error is different in emerging markets). ALL of these non-LCD Epsons use this error pattern, even today. However, it usually throws an error about the pads on the computer ("Printer ink pad is at the end of its service life"); it varies a bit, but most of the newer Epsons call the part in question out now -- others not so much, but mainly old, old ones like the R200 ("Parts inside your printer require replacement").

If you want to open it to check for sure, this video shows how to take this model apart. You can also check this here. I mention this first because, sadly, these newer Epsons (wetness sensor 88/69/68-present) don't have the endurance of the old ones on the waste ink pad; when they moved it, the pad capacity shrunk.
This generation isn't as miserable or waste ink error-prone as the later 2010+ models (especially the AIOs) because it was based on the Artisan 50, which is an update to the R280 and was the last model with a decently sized waste ink pad that didn't get saturated in 2-3 years, guaranteed by the amount of ink Epsons wastes. The Artisan 50 IS still compromised, so make no mistake. However, it's not as compromised as later models, but what saved it was it's based on the R280, which wasn't totally compromised yet, so it still had good waste ink capacity. They all share the same color set (CMYK+LC+LM), which Epson still uses on proper Photo models for consumers.
The fix is to dump the ink outside the printer unless you can find the pad, replace it, and then reset the WIC counter. You can bypass the internal pad; but not the WIC counter.

HOWEVER, the current problem is the new ones with the black carts are tracked by the chip ID and firmware bombed to block 3rd party ink and actively updated under the guise of "security updates".

If the pad is in good shape, check for platen disruptions and ensure the service station cap isn't broken; the R280/Artisan 50 shared that issue from the R200/R220. When the cap is damaged, it can lock up the head and crash the printer as it did to yours. If that's the case, sometimes it can be pushed back down if the clips are intact, and you can move the printhead enough, but if it doesn't push down, you'll need to replace the service cap on the maintenance station.

If neither works, it's the motherboard or a firmware issue. I know the "black cart" machines with the chip tracking and 3rd party ink firmware bombs disguised as "security updates" have a recovery mode, but these are a bit unknown. Look around and see, but I think Epson only recently decided to add a safety mode like firmware recovery.
