Hi, William! I don't know if you've found the answer to your question, but I've been wondering the same thing! On the few occasions I've needed to print on legal-size paper, I've just pulled out the lower papertray, put a sheet or two of legal in on top of the letter-size sheets and closed the tray with a "paper tail" sticking out. It seems ridiculous but it works. However, after seeing your post I pulled the paper tray out, removed the paper and inspected the tray more closely. Lo and behold! - with the paper out, if you look inside the tray to the left, you'll see a "depressable" plastic button adjacent to an arrow with an "LGL" label. It takes a little slight-of-hand, but if you press down on that button and pull at the front of the tray, it slides out into a new locked position -- expanding the extra 3" needed for legal paper and revealing a new "LGL" detent for the paper length adjuster! I'm sure the Canon engineers thought this would be totally obvious to the user but I've owned several Canon printers now and this is the first time, like you, I've been stumped to figure out how to use legal-size. Thanks for posting on the forum so I'd see your question, get motivated by it and finally find the answer to what's been bugging me, too! By the way, Canon, the MX922 is a really great printer! I get wonderful results whether printing photos, web pages or work docs. Really affordable to boot!
To load paper larger than A4 size in the cassette (lower), press down the lock (F) on thecassette (lower), then extend the cassette (lower).
