Thank you Zohaib, i really appreciate it!
I will include a post for each picture i have taken. As you will see, there are two small tabs within the interior scanning area. What may be very difficult to see is that the tallest of two blue tabs, it has a small black arm handing down that seems to hook into it. Now im not sure if this is what is causing the lock, but im sure an expert such as yourself would understand better.
It seems like such a simple issue, but we cannot figure it out! The tab/switch on the output tray roof just wont move into the unlock position.
