Just a word of advice being that you're a new 3800 owner. While it's a fantastic printer, I love mine, you should be aware that you should only ever use the manual front loader for really think paper. I made the mistake of using paper like Hahnemuhle Fine Art Pearl in the front tray, which resulted in the paper getting caught as it was coming out and jamming. Not only ruined a few sheets of paper learning the hard way, but ran the risk of damaging the print head as I tried to remove the paper while it continued to try and print. The correct way to remove paper which has jammed or is in the process of jamming, is to press the power switch to turn the printer off. The print head will park, allowing you to safely remove the paper. I can't imagine ever having to use the front tray, as the paper would be more like a board (stiff and flat). I mainly use the manual rear tray with single sheets, but you have to gently push the top edge of the paper down into the printer and hold it lightly until the printer grabs it. Then it's ready to print. Hope this helps.
