Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
When you tried copying a page from the printers scanner glass, was it also blank? If so, then you need to do a printhead cleaning on the canon machine.

If after 2 cleanings, you still cannot get the machine to put any ink on paper when you trying to copy from the scanner glass, you will need to remove and replace the printhead. You can get a new printhead here. http://amzn.to/1MIOz5R As you can see, its an expensive part.. So It may be worth removing and cleaning manually by hand. If thats needed, we can discuss how.
If however, it will print from the scanner glass, but still prints blank pages from the computer, let me know so we can discuss other options.
I strive to provide great service, and greatly appreciate a rating of excellent ( 5 stars ) selected and submitted below this answer or at the top right of the screen. I always answer follow up questions.
