To scan using a multi-function printer, you need to install the software on your computer. Do you still have the installation disk for your Epson stylus CX3650? You may download it from here: http://esupport.epson-europe.com/ProductHome.aspx?lng=en-GB&data=nKGrQtfEm6nFHFTrlaTOjFTqtAMM0p7d3pb4dtXdKsIU003D&tc=6


Hope it helps!

It appears that this is an overseas model (at least for those here in the US that is) as far as I can tell. This will use the same drivers as the CX3600 model though. Depending on how long you have had this and how often you use it, you may have a waste ink reset situation. While I have not had any personal experience with this model, there are several references on the internet on how to do a reset. There is even an "SSC Service Utility" you can search for that lists this printer as being supported. It cannot reset the ink counters but it may reset the waste.
Good luck, I hope this is of some help.
