The goal is to slide the film down so that it can be pushed, along with the pressure plate, until
the front section of the film back. Don't do this until the film is flush with the top of that
section. Then push the entire pressure plate forward until it “locks” into place in the forward
section, pushing the film into position. It can sometimes happen that the bottom of the
pressure plate, which can't be reached with your fingers, doesn't snap as easily in place as the
top. In this case you can insert a long, flat object such as a small screwdriver or table knife to
press the bottom into position. You can also depending on the Foam Plate (Step 5) to press
the bottom into place, but we recommend doing this before moving on to the next step.
