Epson TM-U220 goes offline in random time

I have Epson TM-U220 with UB-E03 ethernet interface. It is connected to a router with ip address 192.168.1.100.

Recently, the printer goes offline in random time. It didnt happen frequently the first few months of using it. But now it happens everyday.

From my computer i try to ping its ip address and this is the result.

As you can see, without intervention, the printer went completely offline.

Sometimes, it goes back up again by it self, but it is quite rare, im still ping it and learn its behaviour. But if anyone can offer a solution, it would be so much appreciated. Tyvm.
