Actually you don't need tubing - it cost me nothing. - What I did was open the trap door after unscrewing the screw at the bottom - It can be tricky, and BE ADVISED that I tried this on an R200 and I cannot garantee this will work with other printers DO NOT attempt this if you are not comfortable. You have to be extremely careful not to pull out too hard the inner tube, as it is fitted to a pump on the other end and is not held tightly, so it is very easy to pull it out of its place, result, ink will be pumped all over the insides of your printer and its electrical components so unless you want a major mess and possible fire hazards be careful When you remove that door on your R200 use a flashlight and look down, you will see a path going from the pump downwards towards you and going to the right (assuming you are facing the back of the printer) The tube is inside that tunnel and is held in place by a foam like thing at the end of the path, the foam is placed ONTOP of the end of the tube to keep it in place and the waste pads are further to the right- they are series of pads - the first one gets wet first, then when it "leaks" to other pads. What I did was remove that small piece of foam holding the tube down and using a hanger or modified paper clip GENTLY lifting the tube - Prior to that you can drill a hole on the door and pass the tube outside - DO NOT pull it - The tube WILL extend maybe 2 to 2.5 inch out. I use a small empty pill bottle (you can get those at the drug store), I made a hole on the lid (LARGER than the tube to allow air to escape, and gently inserted the tube so it curves down inside the pill bottle - I then hold the bottle in place with those tiny velcro stickers to the base of the printer - so the tube barely comes out and curves in the bottle, whenever bottle gets full I gently remove tube and velcro and empty the bottle. Now the reason I use a tiny bottle is because I don't use that many clean cycles, and when the printer goes into a self cleaning cycle every few days of idle activity, it uses only a small amount of ink. That small bottle will take easily 2 to 3 medium cleaning cycles and maybe 1 to 2 large cleaning cycles and about a dozen so small cycles. A lot of people screw up and pull on the tube - keep in mind you are VOIDING your waranty. You will need a program to reset the waste ink pad counter. I use EPSON's service utility (it is available only to technicians) So you will have to use the SSC utility (FREE) j ust google EPSON SERVICE.
If you are not comfortable with the tube as stated above you can use a coupler and a tube extension but make sure that the container your tube goes into has an air vent, you can either drill the hole larger where the tube goes in OR another tiny hole for te air vent.
