Adjustments can be made for letter, A4 and legal sized paper. Make sure paper is flat in the tray with all four corners below the tabs on the guides. To avoid paper jams do not load paper into this tray while printer is printing. The rear output bin is located at the rear of the printer. The printer always prints to the rear output bin if it is open.
Paper comes out of the printer face-up, with the last page on top.
To open the rear output bin, grasp the handle at the top of the bin. Pull the bin down, and slide out the extension. However, settings in the software you use will override any control panel settings. Two pages will print out. If you have sent a print job from Word or some other application and you see that it isn't coming out of the printer, printing a test page will allow you to see if the printer can output a test page independent of a print command from a computer.
