Printing problem of my printer

I was doing my case study and when I was about to print it, I got frustrated that I could only print a single copy at a time and I had to turn it off and on to print another one. I am using the Canon Images Class mf4270 s/cp/f. The trouble with this, is that the default setting is stuck to 2-sided printing. The field of Copy Setting default reads ''OFF'' for 2 – sided printing while the shortcut button constantly reads ''ON'', which means 2-sided printing is to be done.
I hope someone can help me out with this.
