I am still under warranty and they said to bring it to a service center. i am going to install everything back to normal. The only thing I don't know how to fix is the CIS had a bottle to collect ink from cleanings in the back of the printer. I had to unscrew and pull out a tube to connect. I need to put the tube back in and don't know where that goes. Also a sponge or foam was there. Can anyone tell me where that goes?
