Filling and Priming the EPSON R3000 Refillable Carts for the 1st time

I decided to do the initial fill and prime on one of my R3000 refillable push button to reset carts.
As you will all see, it is extremely easy to do this and should hopefully aliviate any misconceptions or fears about this process.
Please note that in the video I though I had filled the cart to full volume but in fact I had some trapped air which led me to believe that it was full as I did get ink coming out of the top fill hole. Later on I was able to dislodge the air pocket and fill it to the proper volume.
I plan to use nothing but OEM inks on this printer, assuming it will operate properly as it is thus far untested by me.
I am recieving a new OEM PK cart to replace the empty one that is in the printer now.
Assuming all is well I will proceed to produce many videos covering all sorts of processes with this R3000
Hope you all find these useful and are able to get some good information from them.
