Canon has manuals for most of their products on the product support page. For the MG3200 ink jet printer, go to http://www.usa.canon.com/cusa/consumer/products/printers_multifunction/photo_all_in_one_inkjet_printers/pixma_mg3220#BrochuresAndManuals
. In the section marked Recommended Downloads, click on the MG3200 Series User Manual that is appropriate for your computer (Windows OS or Mac OS). If your computer has OS X 10.5, scroll down through the Guides and Manuals section. Place a check in the box to agree to the Canon Disclaimer and then click on the Download button (above the Disclaimer notice). You will be asked if you want to Save or Run the program. If you save the file, you will need to run it to install the manual.
After the manual is installed, access it like any other program. (With Windows 8.1, the new program may not be added to the Desktop, click on the Start button to get the Start Screen and then click on the arrow below the icons. Scroll through the list to find the Canon User's Guide and then launch it. If you right click on the program here, you can add it to the taskbar or the Start Screen.) Browsing through the manual will be like reading a web page with links to the various chapters.
I hope this helps.
