How do you deep clean a Canon Pixma MP520?

Problems with my Canon PIXMA MP520?

• I have had this printer/scanner for 8months ish. Im going to be a mager pain in the behind, but im really sorry and greatful!! I haven't had any trouble or any problems with this untill now, sadly. For some unknown reason, it stopped working.. i think it may have had something to do with me installing a webcam. I therefore, uninstalled the webcam completely.. but it still wouldn't work. I decided to uninstall the printer/scanner and to start over and install it again. Only to find that it wouldnt install it :S i have no idea why it wont.. but here are some of the messages i have been getting up on the computer.. I go all the way through with the installation.. and when the installation thing tells me to plug in the usb.. i do so and a "found new hardware" screen comes up.. so i do as it says.. and then all of a sudden it says "Competing the new found hardware wizard Canon MP520 ser An error occured during the installation if the device The system cannot find the file specified So i just click finish.. (But on the other installation thingy, it says that the printer is detected etc..) Then another screen comes up saying.. "Digital Signature not found" "The microsoft digital signature affirms that software has been tested with windows and that the software has not been altered since it was tested. The software you are about to install does not contain a microsoft digital signature. Therefore, there is no guarantee that this software works correctly with Windows. Canon MP520 ser It just keeps coming up, so it wont install or nothing.. any ideas? pleaase.. if you need to know more just ask and ill add it underneath this posted question. thank you again for taking your time to help me!!
