On the control panel find Network Settings. It will tell you there.

Maybe you should read the user's manual? I've reas cutomer's review at Amazon and looks users have no problem with the scanning feature of this printer. If you don't have the manual, get it from here:

When you installed the machine on your computer, assuming you did a standardinstallation the scanner driver and software should also have been installed. Assuming you are using a Microsoft environment ie Windoze something, you can check your scanners and cameras folder. The MG2520 should be listed in that folder. If not - re-install it. Then go to this page:

Hmm. That model doesn't have the best reputation. Even if you just got it, try running a cleaning cycle; lines across a print usually mean either a clogged jet or debris on the print head. Less often, if it's there no matter what you do, it's a defect in the print head. Canon's Service and Support Page for the MG2520: Canon Support Drivers PIXMA MG2520
