Can I print onto 9 x 12 paper on a canon 3225? How do I set the paper tray?

The reason for that is the front is the paper output tray, the rear tray is where you load the paper. Anything you print, copy, or scanned (to print) will come out the output tray (in front) and will pull paper from the rear tray.

If you go to the printer properties before you send it to print you should be able to choose which tray to print from. Or you can set the default tray in the print driver and then apply it to set it in as default.

The printer will not print as long as the paper output tray is closed.

1. Open the Paper Output Tray (2).
   Put your finger in the rounded indent beside the Paper Output Tray and open it gently.
   
   
2. Open the Output Tray Extension (3).
   Open up and set the Output Tray Extension completely by pressing down the hollow on its front side.
   
   
3. Adjust the position of the Paper Thickness Lever (4).
   Set it to the right when printing on envelopes or T-shirt transfers, and left when printing on any other type of paper.

Is it ok when you just put the document on the glass? If so, the Document feeder needs a whole set of rollers.
Otherwise the document scanner may be bad. This needs to be changed out by a technician.

Check the paper in the cassette as the side brackets that hold it can shift and not allign the paper correctly.

>> It tells me to close the door so it can resume printing on paper normally A4.

It is trying to "ignore" the "bypass" try.

Tell the printer to *ACCEPT* the disk from the "bypass" tray,
rather than from the stack of paper in the A4 tray.

To tell the printer, click the OK button on the printer.

Hello
This can be due to a feeder wrong setting on the printer or on your PC: your printer tries to take paper from the back feeder, whereas your paper is on the front feeder....
try to check these settings in your PC and on your printer, and retry to print, hoping this helps

TRY TO GO ON PAPER TRAY AND LOOK THE PROGRAM IN PAPER TRAY...IF U SEE CHEK THE PAPER SIZE THAT U WANT TO USE...

Have you tried specifying the paper type and weight INSTEAD of the tray. Set the tray properties first, then print. If you leave it on auto tray it will use the tray that matches your paper type and weight.
