This worked for me. In essence, a paper jam has gotten the scanner bulb unit stuck out of place and not resetting to it's default position.
The hardest part was identifying the clips holding the scanner bed and glass into place. They are directly behind the control panel and we pried them apart with a pocket knife. The screws we used allen wrenchs for... metric and the screws are magnetic if one won't come out of it's hole. Also make sure you find the two screws back by the lid hinge. We missed those the first go around.
Good Luck!

Had this problem and feared the worst. Scrap it and buy new. However, read your post, found the spindle in question, gave it a few twists both ways between finger and thumb, PROBLEM GONE!! No tools needed. Can't thank you enough (at least £50-60 saved).
