Product's an MX490 Pixma.
it used to work well until I download this program called Not Another PDF Scanner 2. After I did, I used it and connected the laptop to the printer using a cable (was using wireless connection before). After using it, I figured out I can't use the automatic feeder for it so I decided I'd stick with the program that came with it. Now it won't connect to my laptop. Would really love some help. Thanks.
Edit: after saying on the printer: Connected [OK], it says this on my laptop: Failed to perform cableless setup. Suspend the process and select other setup method by following the instructions on the screens.
