I had same thing happen after a fresh Windows install. It was hard to figure out since it had been working fine until then, but luckily it is simple to fix. Open the Start Menu > Settings > Printers and Faxes folder. Then right-click on the Canon MF4100 Series printer and choose Printing Preferences. In there, change the Paper Size to Letter (instead of A4). You may also have to do this in the Print setup for whatever program you're using to print.

I had the same cr@p of the problem yesterday. The problem was not in the paper. You have to do 2 simple things, from which one will solve the problem.
first, download the latest drivers and install them.
And the more important thing, the problem occurred due to incorrect paper format. Solution is very simple. Open MS word or something similar, file->print.. and before you print open Properties menu. There for the Output Size will be selected "Match Page Size". you don't want that (i don't know why it doesn't work), but the solution is manually select A4, or whatever your page size is.

Chances are the paper size in the cassette doesn't match the paper size (or alignment) that you've tried to print. Verify the paper and alignment of the paper match what you're trying to print, and that the paper guides in the cassette are locked into position for the size and alignment you're working with.

You have the settinigs on the printer wrong. There are two things you need to do:
1. Open the tray and check that the paper guides are set to 8.5 x 11 (letter). There are both length and width guides in the paper tray, and EXEC size is quite a bit off from letter-it is more than 0.5 inch narrower than letter. It is also shorter than letter.
2. On the printer, use the settings button to navigate to the paper size. (The exact wording may vary; it's been a while since I worked on a 4050. It may be under print settings.) Once you find the paper size menu, configure tray 2-yes, I'm sure-to use letter size, any type. By the way, on HP lasers, tray 1 is the fold down tray on the front, tray 2 is the tray that will hold 500 sheets of paper and is the "drawer" that you load. Don't ask me why they use that numbering system.
