Looking for video (or photos) depicting how to remove ASR 33 printer from keyboard

[Bill Degnan]

I am looking for a video or photos that show how one removes the printer
from the keyboard safely on an ASR 33.  I need to get to the underside of
the printer levers so I can re-align them.  I am getting incorrect
characters when I type over half of the keys.  I can see that a few levers
are out of whack or not seated correctly but I believe to get to them
properly I need to put the printer on its side or under a lift to get to
the underside.  I am nervous about detaching the "H" shaped gizmo that
connects the keyboard to the printer.
Thanks
Bill
