3Choose a default paper size for the multipurpose tray from the pop-up menu.

The Print dialog box provides the Auto Select option, which allows the printer to draw paper from any paper source that holds the correct size paper. Similarly, the automatic tray switching feature allows the printer to select another paper source that holds the correct size paper when a paper source runs out. However, the printer is not able to detect the size of paper you may have placed in the multipurpose tray, so you must tell it. If the paper size for the multipurpose tray is the same as the paper in the standard paper cassette (and automatic tray switching is turned on), the printer automatically uses the multipurpose tray as a paper source.

4Choose a default envelope size for the envelope tray from the pop-up menu, if the envelope cassette option is installed.

5Choose printing on one side or both sides of the paper from the pop-up menu.

If you want the binding orientation along the side of the paper (like in a book or magazine), choose “two-sided, no tumbling.” If you want the binding orientation along the bottom side of the paper (like in a calendar), choose “two-sided, with tumbling.”

Note: You must have the optional duplex printing unit to print on both sides of the paper.
