TCT: Have you ever gone to the website
www.sewingmastery.com. The website reviews extensively Pfaff, Bernina, Singer and Husqvarna Viking machines. She does complete videos walking you through every detail on every page in your manual and more. I use it all the time when I have a question about my Performance 5.0. I checked and she does have the QE 4.2 on the site, she probably has your answer. Happy quilting.
